As per our knowledge, there are approximately 500 solar systems in the universe. The solar system consists of the sun, the eight planets and the satellites. Other than these, there are asteroids, comets, dust, minor planets, and gas. The Sun, Mercury, Venus, Earth and Mars constitute the inner solar system, and the asteroid belt lies between the orbit of Mars and Jupiter. Jupiter, Saturn, Uranus, and Neptune are the outer solar system planets. The rotation of the planets causes the day and night, and the revolution of planets around the sun causes the change of seasons. Our solar system is present in the Milkyway galaxy. As per astronomers and scientists, the earth is the only planetary body that supports life.
The sun, eight planets, and satellites make up the solar system. Asteroids, comets, dust, small planets, and gas are among the other objects found in space. The Sun, Mercury, Venus, Earth, and Mars make up the inner solar system, whereas the asteroid belt is between Mars and Jupiter’s orbit. According to our knowledge, there are around 500 solar systems in the universe. The outer solar system planets are Jupiter, Saturn, Uranus, and Neptune. The sun is at the centre of the solar system, and the planets revolve around it in their own orbits. The rotation of the planets causes the days and nights, and the changing of seasons is caused by the revolution of the planets around the sun. Our solar system exists in the Milkyway galaxy. According to scientists and astronomers, the earth is the only planetary body where life can exist. But this can be proven wrong after more discoveries about the universe.
The solar system comprises the sun, eight planets (Pluto is considered as a dwarf planet), and satellites. Other than these, there are also asteroids, comets, dust, small planets, and gases found in space.

The planets rotate on their own axis and revolve around the sun in their own orbits. The rotation causes days and nights, whereas the revolution causes the change of seasons in the planets. The research on our universe is still going on, but there are around 500 solar systems present in our universe, as per the little information we have gathered. Our solar system lies in the Milkyway Galaxy, which appears like a white band in the night sky and is therefore named as Milkyway Galaxy. According to scientists and astronomers, the earth is the only planetary body where life can exist. But this can be proven wrong after other discoveries about the universe.
The sun, eight planets (including Pluto, which is a dwarf planet), and satellites make up the solar system. The inner solar system is made up of the sun, Mercury, Venus, Earth, and Mars, whereas the outer solar system is made up of Jupiter, Saturn, Uranus, and Neptune. Between Mars and Jupiter’s orbits is where the asteroid belt lies. Asteroids, comets, dust, tiny planets, and gases are among the other objects that can be found in space. The sun is the largest star in the solar system, located at the centre of the system, around which all the eight planets revolve. Planets rotate in their own axes and follow their own orbits around the sun. The rotation of the planets in their own axes causes the change of day and night, and the revolution causes the change of seasons throughout the year. Research about the universe is still a vast ongoing process, but different scientists and researchers have come to various conclusions about the solar system. It has been found that the solar system lies in the Milkyway Galaxy. The Milkyway galaxy got its name from the Romans, who thought the earth’s nighttime skyline looked like a band and a patch of milk. As per our little knowledge, we know that there are about 500 solar systems in the universe, but later, there might be some additions. As per scientists and astronomers, the earth is the only planetary body where life can exist, but this can be proven wrong after more research and discoveries about the universe.
What are the components of the solar system?
The solar system consists of the sun, eight planets, satellites, asteroids, gases, comets, and dust particles.
How are days and nights caused?
Days and nights are caused due to the rotation of the planets in their own axes. It will be a day on the sun-facing side of the planet and a night on the other side.

Introduction to Essay Writing on Solar System on Vedantu
An essay is a piece of writing where an author expresses in detail all the information on a particular topic. An essay differs from other writing because it is more structured and it provides the author with their own perspective. In this particular essay, we shall know in detail about the solar system. Use this essay as a reference essay and try writing an essay on the solar system.
Let us begin our learning!
Essay on Solar System
The solar system consists of the sun, eight planets, and sixty-seven satellites of the planets, and a large number of small bodies (comets and asteroids). Earlier, Pluto was considered the smallest planet but now Pluto is not recognized anymore as a planet. The inner solar system comprises Sun, Mercury, Venus, Earth, and Mars. Jupiter, Saturn, Uranus, and Neptune form the outer solar system. These four planets are massive in size; hence they are called Giant Planets. Each planet revolves around the sun in its own orbits at its own speed.
Let us explore all the celestial bodies present in the Solar system.
The Sun was born 4.6 billions of years ago and it was formed from a giant rotating cloud of gasses and dust known as solar Nebula. The sun is the biggest star present at the center of the solar system. It is a self-luminous sphere of gasses. Its gravitational force holds the entire solar system. It has a radius of 695,508 kilometers and is 150 million kilometers away from Earth.
Mercury is the smallest and closest planet to the sun. It is also called Swift planet because it completes its revolution in 88 earth days. Its diameter is only one third of Earth but its density is about the same. The temperature of this planet is as high as 450 degrees Celsius in the mornings and nights are freezing cold. The surface of this planet is filled with craters, mountains and valleys.
Venus is the second closest planet to the sun and the hottest. Venus is the brightest planet and hence called the morning star. Venus is named after the Roman Goddess of love and beauty. Venus completes one revolution around the sun in 255 earth days. Venus spins clockwise on its orbits unlike other planets. Its surface is covered with clouds, craters, mountains and lava plains.
The third planet in the solar system is Earth. This is the only planet that sustains life. It is called the Blue planet because 70% of the earth's surface is covered with water. Earth takes 365 days to complete one revolution around the sun. This planet has only one natural satellite, the Moon.
The fourth planet from the sun in the solar system is Mars. It appears as a red-orange ball because of the presence of iron oxide and so it is called the Red planet. It is the second smallest planet after Mercury. Mars is named after the Roman God of war. Its surface is covered with volcanoes, craters all over.
Jupiter is the largest planet in the solar system. Jupiter is rich in hydrogen and helium gas and so it is also called a Gas Giant planet. Jupiter takes 4333 earth days to complete one revolution around the sun. This planet has 79 satellites. Jupiter has four rings.
Saturn is the least dense planet in the solar system. It is the second-largest planet. Saturn can float in water because it is made up of gasses like helium. The beautiful rings around the planet are made up of bits of ice, rock, and dust. Saturn revolves very slowly around the sun. This planet is named after the Roman God of agriculture and wealth.
Uranus is the coldest planet in the solar system. It takes 84 earth years to complete one revolution around the sun. Uranus is called an ice giant planet because its layer is made of ice and hydrogen, helium and methane. Uranus looks blue in color because of the presence of methane. Uranus has 27 satellites.
Neptune is the eighth and the farthest planet from the sun in the solar system. Neptune is named after the Roman God of the sea. Its atmosphere is made up of hydrogen, helium and methane and the presence of methane gives the color blue to the planet. It takes 165 earth years to complete one revolution. Neptune has 6 rings.
Comets and Asteroids:
Comets and Asteroids are the small celestial bodies that rotate around the sun. Asteroids are made up of rocks, metals and water. Comets are made up of frozen ammonia, methane and small amounts of rocky material.

What Is the Solar System?
The solar system comprises various celestial bodies held together by the sun’s gravitational pull, which sits at its centre. This dynamic system is located in the Milky Way galaxy and spans a distance of billions of miles. The major constituents of the solar system are the sun, eight planets, their moons, and a range of smaller objects like asteroids, comets, and dwarf planets. It is an intricate dance of objects revolving around the sun, each following its unique path and exhibiting individual characteristics.
How Does the Solar System Work?
The sun is the heart of the solar system, a colossal ball of gas undergoing nuclear fusion. It emits immense heat and light, making life possible on Earth. The sun’s gravitational force is so strong that it keeps all the planets and celestial bodies in their orbits.
The planets orbit the sun in elliptical paths. Like Mercury and Venus, those closest to the sun complete their orbits quicker than those farther away, such as Neptune . The force of gravity also ensures that moons orbit planets. For example, our Earth has one moon, while Jupiter boasts 79 known moons!
The balance of gravity and the momentum of celestial objects keep everything in place. Without the sun’s gravitational pull, planets would drift away into the vastness of space.
Celestial Bodies Exist in the Solar System
![solar system essay for class 4 Celestial Bodies Exist in the Solar System](https://cdn.cdnparenting.com/articles/2023/10/12192514/Celestial-Bodies-Exist-in-the-Solar-System.jpg)
Our solar system’s central star provides energy and light that drive life on Earth.
There are eight in total. The inner planets (Mercury, Venus, Earth, and Mars) are rocky, while the outer planets (Jupiter, Saturn, Uranus, and Neptune) are gas giants or ice giants.
Natural satellites that orbit planets. Their number varies from planet to planet.
4. Asteroids
Rocky fragments remain from the formation of the solar system. Most are found in the asteroid belt between Mars and Jupiter.
Comets are icy bodies that come from the solar system’s outer regions. When they approach the sun, they develop glowing tails.
6. Dwarf Planets
These celestial bodies orbit the sun and have enough mass for their self-gravity to overcome rigid body forces (2) . However, they still need to clear their neighbouring region of other objects. Pluto is the most famous dwarf planet.
7. Kuiper Belt & Oort Cloud
These are regions beyond Neptune filled with millions of icy objects. The Kuiper Belt is closer than the Oort Cloud and is the birthplace of short-term comets (1) .
Our solar system is breathtakingly vast and dynamic, filled with various celestial bodies. Its complex mechanisms and operations provide invaluable insights into the universe’s workings.

Introduction.
![solar system essay for class 4 The solar system consists of the planets that orbit the Sun as well as such smaller bodies as dwarf planets, comets, and asteroids. The Oort Cloud is part of the solar system. It consists of countless small, icy objects.](https://cdn.britannica.com/92/95392-004-F8125E8B.jpg)
The solar system itself is only a small part of a huge system of stars and other objects called the Milky Way galaxy . The solar system orbits around the center of the galaxy about once every 225 million years. The Milky Way galaxy is just one of billions of galaxies that in turn make up the universe .
![solar system essay for class 4 U.S. astronauts took a photograph from space of a huge flare of energy on the Sun.](https://cdn.britannica.com/08/4508-004-B32FA282.jpg)
The Solar Wind
The gases that surround the Sun shoot out a stream of tiny particles called the solar wind. It flows outward through the whole solar system. The solar wind is what causes auroras, or displays of colored light in the night sky in parts of Earth. In the Northern Hemisphere these auroras are called the northern lights.
The Planets
![solar system essay for class 4 Use this interactive to explore the planets.](https://cdn.britannica.com/18/238518-049-AC2B446B.jpg)
Scientists used to call Pluto the ninth planet. But in 2006 scientists decided that several objects in the solar system, including Pluto, should be called dwarf planets.
Millions of small chunks of metal and rock called asteroids also orbit the Sun. Most asteroids are found in a ring between Mars and Jupiter. They are believed to be debris, or bits of material, left over from collisions between other bodies in the solar system. The largest asteroids are hundreds of miles in diameter, but most are much smaller. Small asteroids regularly fall to Earth or burn up in the sky as glowing meteors .
![solar system essay for class 4 Comet Hale-Bopp blazes across the sky in an image taken from Earth in 1997.](https://cdn.britannica.com/22/191122-004-0151E4B1.jpg)
Outer Regions
Beyond Neptune lies the Kuiper Belt, a flat ring of millions of small, icy objects. These objects orbit the Sun at a very great distance. They are mostly 30 to 50 times farther from the Sun than Earth is.
At the outer reaches of the solar system is the Oort Cloud. It is a huge cloud of countless small, icy objects. The Oort Cloud surrounds the rest of the solar system.
How the Solar System Was Formed
The solar system was formed about 4.7 billion years ago. It probably started as a loose cloud of gas and dust. Scientists think that a force called gravity pulled parts of the cloud together into clumps. The largest clump was squeezed together so tightly that it got very hot. This clump eventually became the Sun. Over millions of years the other clumps became the planets. The Sun’s strong gravity eventually pulled the planets into their orbits. Over time some of the leftover clumps became asteroids, comets, and other small, icy objects.
Exploring the Solar System
![solar system essay for class 4 A space probe named Voyager 2 traveled deep into the solar system. It took photos of Neptune and its Great Dark Spot.](https://cdn.britannica.com/48/113148-004-F2F40568.jpg)
Other Planetary Systems
The solar system is also known as a planetary system. Since the 1990s scientists have found many planetary systems beyond our solar system. In these systems, one or more planets orbit a star—just as the eight planets in our solar system orbit the Sun. These planets are called extrasolar planets. Finding other planetary systems is not easy, however, because extrasolar planets appear much dimmer than the stars they orbit. As space probes travel farther away from Earth, they are likely to discover more extrasolar planets.

The universe consists of more than 500 solar systems as of now or as of our limited knowledge on the universe. Our solar system is present inside the Milkyway galaxy. The Milkyway galaxy is called so because the Romans named it as they found the earth’s skyline at night to resemble that of a band and a patch of milk. The solar system is the most important part of our Milkyway galaxy. According to experts and astronomers, the solar system is the only planetary body in the universe that supports life. And earth, a part of the solar system, is the only planet that supports life in the universe. But this can easily be false since man has not discovered all the aspects of our universe.
Solar systems consist of eight planets, which are Mercury, Venus, Mars, Earth, Jupiter, Saturn, Uranus and Neptune. Pluto was also a planet but it was derecognized a few years ago because of its size. The main criteria for being a planet are it should orbit around the sun, it should have sufficient mass to assume hydrostatic equilibrium and it should have a clearly defined neighborhood around its orbit. Pluto failed in the second criterion. But Pluto is known as a dwarf planet. All these decisions of naming, recognizing and derecognizing of planetary objects are taken by the International Astronomical Union (IAU). Basically, IAU is an international body that consists of astronomers and scientists all across the world with the main objective and goal of promoting and safeguarding the astronomical sciences in every sphere, through collective international cooperation.
Each planet present in the solar systems revolves around the sun inside their own orbits at their own speed. This is an essential criterion to be declared as a planet in the solar system.
Each of the planets that we mentioned has its own characteristics, which is given below
Characteristics of the Planets in the Solar System

Essay on Solar System: Our solar system consists of one Sun and eight (formerly nine) planets. These eight planets are gravitationally bound by the Sun on their orbits. Apart from these eight planets, there are more than 210 known planetary satellites, asteroids, comets, and other icy bodies that are assembled in the Solar system.
The first four planets are called terrestrial planets (Mercury, Venus, Earth, and Mars) the two gas planets (Jupiter and Saturn), and the other remaining ones are ice giants (Neptune and Uranus.)

Learn about the smallest planet in our solar system
The Sun is the primary source of light and energy and is about 93 million miles from the Earth. It is the only star in our solar system and one of the more than 100 billion stars in the Milky Way. The surface of the Sun is about 5,500 degrees Celsius (10,000 degrees Fahrenheit) hot and the temperature reaches 15 million Celsius (27 million Fahrenheit).
In terms of age and size, the Sun is 4.5 billion years old, composed of hydrogen and helium with a diameter of about 865,000 miles which is approximately 1.4 million kilometres.
Inner Planets (Terrestrial Planets):
The planets that are made of rocks and metals are known as Inner Planets or Terrestrial Planets. These planets are comparatively small in size compared to the other outer planets. The description of these four planets is as follows:
1. Mercury—The Swift Planet
Mercury is the swiftest planet in our solar system which completes an orbit around the Sun in just 88 Earth days. Its proximity to the Sun contributes to extreme temperature variations, from scorching highs to freezing lows.
With minimal atmosphere, Mercury lacks the protective blanket found on the Earth, exposing its surface to harsh solar radiation.
2. Venus—The Evening Star or Morning Star
Venus, which is often referred to as the evening star or morning star, depends on its position relative to the Sun. When Venus is trailing the Sun, it is the evening star, visible after the sunset. Conversely, when ahead of the Sun, it is the morning star, appearing before sunrise.
This dual identity arises from Venus´s orbit, positioning it closer to the Sun than Earth and causing varied visibility during different parts of the orbital journey.
3. Earth—Blue Planet
The home planet to all living things is Earth. It is the only planet that is known for the existence of life.
The surface of the Earth is made up of the crust, the core, and the mantle. It is a giant rocky planet with a circumference of about 40,075 kilometers; 71 percent or ¾ th of the Earth is covered with oceans and seas. A large area covered with water makes this planet a Blue Planet.
4. Mars—Red Planet
The fourth planet of the solar system, Mars, is the most explored planet by the National Aeronautics and Space Administration (NASA.) The reason behind so many missions or research for Mars is to hope for the existence of extraterrestrial life on the planet.
Apart from the possibility of life on Mars, the planet is also known for its presence of iron oxide that turns the planet reddish in appearance.

Outer Planets (Gas Giants)
5. Jupiter—King of Planets
Jupiter is the first planet of our solar system in the category of outer planets, also known as gas giants. According to NASA, the U.S. government agency, the planet’s size is more than twice that of all other planets combined.
Except for Jupiter’s size, the solar system’s first outer planet is made up of leftover gases from the formation of the Sun.
6. Saturn—Ringed Planet
The sixth planet from the Sun is Saturn. It is also known as the ringed planet and the second-largest solar system planet.
The three distinctive features that make Saturn different from other planets are its huge 145 moons, visibility from the Earth with the naked eye, and the seven main rings named D, C, B, A, F, G, and E from the outward side of the planet.
7. Uranus—Ice Giant
The seventh planet from the Sun, Uranus, is one of the two ice giants in the list of the outer solar system. The planet is featured with the third largest diameter which makes the planet the third largest in the solar system.
Other than massive size, Uranus is made up of three dense icy materials, methane, ammonia, and water – above all a small rocky core.
8. Neptune—Blue Giant
The third largest and eighth planet of the solar system is Neptune. According to NASA, the farthest planet from the Sun is more than 17 times Earth’s size and nearly 58 times the dimensions of Earth’s volume.
The cool blue planet, due to the absorption of infrared light by the planet’s Methane atmosphere, comprises a core with the capacity to pick up a lot of gas, making Neptune impossible for the existence of life.
Also Read: Essay on Space Exploration
Our Solar system is incomplete without the Moon, a planetary large natural object that travels around the Earth. However, the Moon does not make its light but it reflects the light of the sunlight.
The total number of moons in our Solar system is 290, out of which one Moon belongs to Earth, two to Mars, 27 to Uranus, 95 to Jupiter, 146 to Saturn, 5 to dwarf planet Pluto, and 14 to Neptune.
The solar system consists of the Sun, terrestrial planets, gas giants, Earth’s Moon, celestial bodies , and various other objects. The unique formation and dynamics continue to amaze scientists offering a glimpse into the vastness and beauty of our cosmic neighbourhood.

The Solar System is made up of the Sun and all of the smaller objects that move around it. Apart from the Sun, the largest members of the Solar System are the eight major planets. Nearest the Sun are four fairly small, rocky planets - Mercury, Venus, Earth and Mars.
Beyond Mars is the asteroid belt – a region populated by millions of rocky objects. These are left-overs from the formation of the planets, 4.5 billion years ago.
On the far side of the asteroid belt are the four gas giants - Jupiter, Saturn, Uranus and Neptune. These planets are much bigger than Earth, but very lightweight for their size. They are mostly made of hydrogen and helium.
Until recently, the furthest known planet was an icy world called Pluto. However, Pluto is dwarfed by Earth’s Moon and many astronomers think it is too small to be called a true planet.
An object named Eris, which is at least as big as Pluto, was discovered very far from the Sun in 2005. More than 1,000 icy worlds such as Eris have been discovered beyond Pluto in recent years. These are called Kuiper Belt Objects. In 2006, the International Astronomical Union decided that Pluto and Eris must be classed as “dwarf planets”.
Even further out are the comets of the Oort Cloud. These are so far away that they are invisible in even the largest telescopes. Every so often one of these comets is disturbed and heads towards the Sun. It then becomes visible in the night sky.

QUICK CONCEPT REVIEW UNIVERSE
Solar System: The sun, its planets and all the objects moving around them collectively are called solar system. The solar system is in a galaxy known as "the milky way". About 99.86 percent of the mass of the solar system is made up of the sun. There are 8 planets in the solar system.
- Sun is a ball of hot, burning gases. It is made of gases called hydrogen and helium.
- Sun is the nearest star to the earth.
- Sun is the source of all energy for life on earth.
- The outside of the sun is 11,000 degrees Fahrenheit.
- On the sun's surface, there are dark patches known? as sunspots. These are patches of gas that looks, dark since they are cooler than their surroundings.
- Planets are heavenly bodies, which revolve around the sun in elliptical orbits.
- All planets fall in 2 groups Inner Planets: Mercury,: Venus, Mars and Earth are called inner planets. Outer Planets: These are Jupiter, Saturn, Uranus and Neptune,
- Between Inner &. Outer planets, there is a ring of small bodies, which are made of rock & metal, these are called Asteroids. They also keep moving around the sun. This ring is also called Asteroids belt.
- The inner planets are also called the rocky planets, because they are made of rocks.
Amazing Facts
- A person of 60 kg weight barely will weigh 10 kg on moon. That means, you would weigh 1/6 th of your weight on moon. This happens due to gravitational pull at different places.
- It takes about 1.25 seconds for moonlight to reach the earth whereas sunlight reaches earth in 8 minutes 19 seconds, so you can judge how close moon is to us & how far sun is from earth.
- In space, astronauts cannot cry, because there is no gravity, so the tears can’t flow.
- Saturn has such a low density that it would float if put in water.
- Mercury has large variations in temperatures during day and night.
- Mercury does not have any satellite.
- There is no water or atmosphere on Mercury.
- Mercury can be seen with naked eyes.
- A year at Mercury is of 88 days as it takes Mercury 88 days to orbit the sun, so Mercury has shortest year among all planets.
- There are no seasons on Mercury's surface.
- Venus orbits the sun once in about 225 earth days.
- Venus has no oceans. Its atmosphere is made mostly of carbon dioxide. There is almost no water vapour in its air. Venus is totally covered by clouds, this is why it is also called Veiled planet.
- There are also many volcanoes on Venus. The volcanoes are not active anymore, which means they do not erupt.
- Venus is covered by thick clouds, so it reflects lot of sunlight making it brightest planet. Also it is the hottest planet of solar system.
- Venus reaches its maximum brightness shortly before sunrise or shortly after sunset, so it is also known as the Morning star or Evening star.
- It has the slowest rotation in the solar system.
Historical preview
- For many thousands of years, humanity, with a few notable exceptions, did not recognize the existence of the solar system. The invention of telescope has led to the discovery of further planets and moons. In more recent times, improvements in the telescope and the use of unmanned spacecraft have enabled spacecraft have enabled the investigation of various geological phenomena.
- Origin of some celestial words: planet word comes from Greek word planasthai; which means to wander, satellite word comes from Latin word stateless, which means attendant, solar also comes from a Latin word solar also comes from a Latin word solaris meaning sun.
- There were nine planets, until Pluto was downgraded to dwarf planet status in 2006.
- It is the largest of the four inner planets.
- Earth is often called the "Water Planet" because it is the only planet in our solar system which has liquid water on its surface. About 71% of the surface of earth is covered by water. The other part of earth is made up of continents and islands which have different landforms on them.
- It reflects about 1/3 rd of sunlight it receives.
- Earth is called the blue planet. From space the oceans combined with the atmosphere makes the planet look blue.
- Due to gravity, the layer of gases remains attached to it (which is known as atmosphere), it prevents too much heat or UV rays from sun reaching the earth.

- It's diameter is l/4th of the earth.
- It looks bigger to us as it is very close to us.
METEORS, METEORITES AND METEROIDS
- A meteoroid is a small rock or particle of debris in our solar system. They range in size from dust to around 10 metres in diameter.
- A meteoroid that burns up as it passes through the earth's atmosphere is known as a meteor. If you've ever looked up at the sky at night and seen a streak of light or 'shooting star' what you are actually seeing is a meteor.
- A meteoroid that survives falling through the earth's atmosphere and colliding with the earth's surface is known as a meteorite.
STARS, GALAXIES AND CONSTGELLATIONS
A star is a gigantic, glowing ball of plasma.
Stars are first formed as clouds of dust and gas.
Stars give off a tremendous amount of energy in the form of light and heat.
The star that is closest to the earth is the sun.
Galaxy is a collection of stars, gas, and dust bound together by gravity. The smallest galaxies may contain only a few hundred thousand stars, while the largest galaxies have thousands of billions of stars. The Milky Way galaxy contains our solar system.
CONSTELLATION
A constellation is a group of stars, which seem to be forming different figures, letters, etc. at night.
This term has come from the latin words con, which means together and Stella, which means star.
Example: Ursa Minor, Ursa Major etc.
- An asteroid is a large rock in outer space. Some, like ceres, can be very large, while others are as small as a grain of sand.
- 26 very large asteroids have been discovered, which are mostly the big ones. But there are still millions of smaller ones that we are yet to see because they are too tiny,
A celestial body moving about the sun, consisting of a central mass surrounded by an envelope of dust and gas that may form a tail that streams away from the sun. When close enough to the sun they display a visible coma (a fuzzy outline or atmosphere due to solar radiation) and sometimes a tail.

500 words essay on sun.
The sun is the largest star in our solar system. It is present in the centre of the earth and the planets orbit around the sun. The sun is spherical in shape and scientists state that it contains a mass of hot plasma. It is essential for our planet earth as it gives us the energy which we require for the existence of life. Through the essay on sun, we will go through the details and their importance.
![solar system essay for class 4 essay on sun](https://d1whtlypfis84e.cloudfront.net/guides/wp-content/uploads/2021/02/23085114/Sample-25-1024x724.png)
All about the Sun
The sun is said to have the same age as the solar system. In other words, scientists believe it is four and a half billion years old. We derived this age from studying rocks from the moon which is also believed to have existed at the same age as the sun.
The sun is basically a large sphere that glows because it contains hot gases. The major gases which make up the sun are hydrogen and helium. In other words, it has 70% hydrogen and 28% helium .
It also contains other hot gases like carbon, oxygen, and nitrogen. Further, there are other elements like silicon, neon, sulfur and magnesium. The sun is a very bright star which is four hundred thousand times brighter than the full moon.
We can measure the brightness of the stars in the solar system by using magnitudes. Thus, the magnitude of the sun is 26.74 which are very bright. It is also the reason why we can easily look at the moon with our bare eyes but not so easily at the sun.

Importance of Sun
Sun is an essential part of our lives and the solar system . On earth, it offers us solar energy. Solar energy acts as an alternative source of energy from electricity which can offer electricity through solar cells.
The energy of the sun helps in the growing of crops. Moreover, the crops depend on the sun to grow and to make their own food. Further, the energy of the sun also warms up our planet earth.
If there was no sun, our earth would have been a cold planet that wouldn’t have been able to support life. The energy of the sun also enables the water cycle. In other words, when the rainwater on the surface evaporates, it forms clouds to make it rain.
Finally, we can also use the energy of the sun at home for serving functions like drying our food and clothes. Thus, the sun provides us with numerous benefits which makes life easier on earth.
Conclusion of the Essay on Sun
The sun is an essential component of the solar system. It is what has made it possible for life to exist on earth. Thus, it provides us with many benefits which we must be thankful for. However, it is also important to remember to not indulge excessively in the sun as it may have some ill-effects as well.
FAQ of Essay on Sun
Question 1: What is the importance of the sun?
Answer 1: Sun radiates light and heat which is responsible for the existence of life on Earth. It is because plants require sunlight for growing and animals as well as humans need plants because of their production of oxygen. If the earth does not receive heat from the sun, it will freeze.
Question 2: What vitamin does the sun give us?
Answer 2: The sun gives us Vitamin D. Our body creates this vitamin when we get direct sunlight on our skin when we are outdoors. From late March to the end of September, most regions of the world receive vitamin D in abundance from the sunlight.

Short Essay on Solar System and Planets (200 words)
The universe is massive. It is much bigger than we can imagine and our solar system is just a small part of it. Our solar system houses a big, bright star called the Sun. The Sun is a rich source of electromagnetic energy that it exudes in the form of light and heat. There are eight planets in our solar system namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These planets revolve around the sun in a fixed path referred to as the orbit. Several other smaller objects also move around the sun.
Many planets in our solar system have natural satellites called the moon. While Earth has one moon, Mars has two, Neptune has 14 moons, Uranus has 27 moons, Saturn has 62 moons and Jupiter has as many as 79 moons. Even the dwarf planet Pluto has 5 moons. Mercury and Venus, on the other hand, do not have any moon. Just as the planets move around the Sun in a fixed path, moons orbit around their respective planets.
In addition to the Sun, planets and moons, our solar system consists of several other celestial bodies called the comets, asteroids and meteoroids. While our solar system has only one star, many other solar systems are known to have at least two stars.
Essay on Solar System and Planets (300 words)
Introduction
Our solar system was formed billions of years ago. It consists of numerous celestial bodies including planets, satellites, asteroids, comets, meteorites and a massive star. Our solar system forms a part of the Milky Way Galaxy. Various celestial bodies in our solar system revolve around the Sun directly or indirectly.
The Formation of the Solar System
It is believed that around 4.6 billion years ago, the gravitational collapse of a giant interstellar molecular cloud gave shape to our solar system. Major part of the collapsing mass collated at the centre, that formed the Sun. The remaining mass flattened into a proto planetary disk and formed the planets, satellites and other objects in the solar system. Planet Jupiter, the biggest planet in our solar system, contains major chunk of the remaining mass.
Our solar system is believed to have evolved substantially since its inception. Many new moons have come into shape from the gases and dust around the planets. Several collisions among the celestial bodies have also occurred and still continue to occur thereby contributing to the evolution of the solar system.
The Discovery of Planets
For thousands of years astronomers believed that Earth was stationary and formed the centre of the universe. It was in the 18 th century that the astronomers accepted that Earth orbits around the Sun.
In 2 nd millennium BC, Mercury, Venus, Mars, Jupiter and Saturn were identified by ancient Babylonian astronomers. Later, Nicolaus Copernicus also identified them. Uranus was discovered by famous astronomer, Sir William Herschel in 1781. Neptune was discovered by English astronomer and mathematician, John Couch Adams in the year 1846. It was in the year 1930 that the ninth planet, Pluto was discovered. Astronomer Clyde Tombaugh discovered Pluto which is now identified as a dwarf planet.
The study of the universe and heavenly bodies is one of the most fascinating studies. Through continuous research, astronomers have found out several surprising facts about the universe and our solar system. Our solar system is ever evolving and newer facts are being discovered and studied by researchers year after year.
Essay on Solar System and Planets (400 words)

There are eight planets in the solar system. These are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The planets have been divided into two groups – Terrestrial Planets and Giant Planets. Planets vary based on their size, geological features, mass, number of satellites and various other factors. No traces of life have been found on any planet apart from Earth.
The Dwarf Planets
There are five dwarf planets in our solar system. These are Pluto, Ceres, Haumea, Eris and Makemake. While Ceres is situated in the asteroid belt others are located in the outer solar system. Dwarf planets are quite like the full size planets. The only difference is that the full size planets have cleared the objects in the area of their orbit whereas the dwarf planets have not.
Astronomers claim that there are six other objects in our solar system that are akin to the dwarf planets. These may be officially recognized as dwarf planets in the times to come.
There are a total of 193 moons in our solar system as per a research conducted in the year 2008. Out of these, 185 moons orbit around the full size planets and 8 moons revolve around the dwarf planets. Moons come in various sizes and shapes. They differ from each other in various ways. Most of the moons are airless. However, there are some that have atmosphere. Some even have hidden oceans. Each planet has different number of moons. Earth has just one moon while Jupiter has the highest number of moons. It has a total of 79 moons. Moons orbit around their respective planets.
In addition to the aforementioned, there are many other celestial bodies in our solar system. These include the Interplanetary Medium, Kuiper Belt, Oort Cloud, asteroids and meteoroids. The Kuiper Belt and Oort Cloud comprise of billions of icy objects. Each celestial body in our solar system is unique with its own set of features.

Our Solar System – A Small Part of the Universe
Our solar system is huge but nothing compared to the size of the universe. The universe is humongous and is believed to encompass numerous solar systems consisting of several planets, stars and other heavenly bodies. The universe is all space and time and it is not possible to calculate its spatial size. The size of the observable universe is estimated to be 93 billion light years.
The Galaxies and Solar Systems
Research shows that just like our solar system there are numerous other solar systems in the universe. The universe consists of billions of galaxies. Each of these galaxies has uncountable stars and many of these stars are said to have solar systems of their own. The size of the stars, the number of planets, the geological features of the planets, the number and size of the natural satellites vary from solar system to solar system.
Our solar system is a part of the Milky Way Galaxy. The Milky Way Galaxy is huge. It has more than 100 billion stars. More than 2500 stars with planets orbiting around them have been discovered in the Milky Way Galaxy. The study in this field is going on constantly. There are numerous planetary systems that the scientists and astronomers are yet to discover.
Our Solar System
Our solar system encompasses Sun which is a big ball of fire. Sun is stationary and forms the centre of our solar system. Eight planets namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune revolve around the Sun. Each of these planets move in a fixed path in its own set speed. The geological features of each of these planets are different. While Neptune is freezing cold, Venus is scorching hot. Similarly, while Jupiter is massively big, Mercury is comparatively very small in size. The planet is even smaller than some of the moons in our solar system. The atmosphere of each of the planets is different. Planets have been divided into two groups and the features of the planets within each group also vary vastly.
Earth is the only planet in our solar system which is known to have life. It is filled with vast oceans and gases such as oxygen and nitrogen that render life. Mars is said to share some similarities with Earth. Evidences of ice have been found on the planet. The planet is extremely cold and thus life there seems impossible. However, it is believed that the planet was once wet and warm and life existed here. Astronomers are studying this planet closely and have found many interesting facts about the same. These planets have different numbers of natural satellites.
Apart from this, there are five dwarf planets in our solar system. These are Ceres, Haumea, Makemake, Eris and Pluto. Earlier there were nine planets in our solar system and Pluto was one among them. However, it has now been termed as a dwarf planet.
The Universe is vast and there is a lot to study and discover. Scientists have studied our solar system deeply for centuries and are now moving beyond to study other solar systems and galaxies. A lot of interesting facts about this enchanting universe are likely to surface in the times to come.
Long Essay on Solar System and Planets (600 words)
Our solar system consists of eight planets that revolve around the Sun, which is central to our solar system. These planets have broadly been classified into two categories – inner planets and outer planets. There are four inner planets, Mercury, Venus, Earth and Mars. The inner planets are closer to the Sun and smaller in size as compared to the outer planets. These are also referred to as the Terrestrial planets. Jupiter, Saturn, Uranus and Neptune are termed as the outer planets. These are massive in size and are often referred to as Giant planets.
Here is brief information about each of these planets:
The smallest planet in our solar system, Mercury is also the closest to the Sun. Its geological features consist of lobed ridges and impact craters. Being closest to the Sun, Mercury’s temperature sores extremely high during the day time. It can go as high as 450 degree Celsius. Surprisingly, the nights here are freezing cold.
Mercury has a diameter of 4,878 km. It does not have any natural satellite.
Venus is said to be the hottest planet of our solar system. It has a toxic atmosphere that traps heat. It is also the brightest planet and is visible to the naked eye. It has a thick silicate layer around an iron core which is similar to that of Earth. Astronomers have seen traces of internal geological activity on this planet.
Venus has a diameter of 12,104 km. Just like Mars, Venus also does not have any natural satellite.
Earth is the largest inner planet. Two-third of this planet is covered with water. It is the only planet in our solar system where life is known to exist. Earth’s atmosphere, which is rich in nitrogen and oxygen, makes it fit for the survival of various species of flora and fauna. However, human activities are having negative impact on its atmosphere.
Earth has a diameter of 12,760 km. It has one natural satellite, the moon.
Mars, the fourth planet from Sun, is often referred to as the Red Planet. The iron oxide present on this planet gives it a reddish appeal. The planet is cold and has geological features similar to that of Earth. This is the reason why it has captured the interest of astronomers like no other planet. Traces of frozen ice caps have been found on the planet.
Mars has a diameter of 6,787 km and two natural satellites.
Jupiter is the largest planet in our solar system. It has a strong magnetic field. It largely consists of helium and hydrogen. It has a Great Red Spot and cloud bands. A giant storm is believed to have raged here for hundreds of years.
Jupiter has a diameter of 139,822 km and has as many as 79 natural satellites.
Saturn is known for its ring system. These rings are made of tiny particles of ice and rock. Its atmosphere is quite like that of Jupiter as it is also largely composed of hydrogen and helium.
Saturn has a diameter of 120,500 km. It has 62 natural satellites that are mainly composed of ice.
Uranus, the seventh planet from Sun, is the lightest of all the giant, outer planets. It has a blue tint which is because of the presence of Methane in the atmosphere. Its core is colder than the other giant planets. The planet orbits on its side.
Uranus has a diameter of 51,120 km and 27 natural satellites.
The last planet in our solar system, Neptune is also the coldest of all. It is around the same size as the Uranus but is much more massive and dense. Neptune’s atmosphere is composed of helium, hydrogen, methane and ammonia. It experiences extremely strong winds. It is the only planet in our solar system which is found by mathematical prediction.
Neptune has a diameter of 49,530 km. It has 14 natural satellites.
Scientists and astronomers have been studying our solar system for centuries and the findings are quite interesting. Various planets that form a part of our solar system have their own unique geological features and are different from each other in several ways.

Short Essay on Solar System and Planets (200 words)
The universe is massive. It is much bigger than we can imagine and our solar system is just a small part of it. Our solar system houses a big, bright star called the Sun. The Sun is a rich source of electromagnetic energy that it exudes in the form of light and heat. There are eight planets in our solar system namely, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. These planets revolve around the sun in a fixed path referred to as the orbit. Several other smaller objects also move around the sun.
Many planets in our solar system have natural satellites called the moon. While Earth has one moon, Mars has two, Neptune has 14 moons, Uranus has 27 moons, Saturn has 62 moons and Jupiter has as many as 79 moons. Even the dwarf planet Pluto has 5 moons. Mercury and Venus, on the other hand, do not have any moon. Just as the planets move around the Sun in a fixed path, moons orbit around their respective planets.
In addition to the Sun, planets and moons, our solar system consists of several other celestial bodies called the comets, asteroids and meteoroids. While our solar system has only one star, many other solar systems are known to have at least two stars.

Essay on Solar System and Planets (300 words)
Introduction
Our solar system was formed billions of years ago. It consists of numerous celestial bodies including planets, satellites, asteroids, comets, meteorites and a massive star. Our solar system forms a part of the Milky Way Galaxy. Various celestial bodies in our solar system revolve around the Sun directly or indirectly.
The Formation of the Solar System
It is believed that around 4.6 billion years ago, the gravitational collapse of a giant interstellar molecular cloud gave shape to our solar system. Major part of the collapsing mass collated at the centre, that formed the Sun. The remaining mass flattened into a proto planetary disk and formed the planets, satellites and other objects in the solar system. Planet Jupiter, the biggest planet in our solar system, contains major chunk of the remaining mass.
Our solar system is believed to have evolved substantially since its inception. Many new moons have come into shape from the gases and dust around the planets. Several collisions among the celestial bodies have also occurred and still continue to occur thereby contributing to the evolution of the solar system.
The Discovery of Planets
For thousands of years astronomers believed that Earth was stationary and formed the centre of the universe. It was in the 18 th century that the astronomers accepted that Earth orbits around the Sun.
In 2 nd millennium BC, Mercury, Venus, Mars, Jupiter and Saturn were identified by ancient Babylonian astronomers. Later, Nicolaus Copernicus also identified them. Uranus was discovered by famous astronomer, Sir William Herschel in 1781. Neptune was discovered by English astronomer and mathematician, John Couch Adams in the year 1846. It was in the year 1930 that the ninth planet, Pluto was discovered. Astronomer Clyde Tombaugh discovered Pluto which is now identified as a dwarf planet.
The study of the universe and heavenly bodies is one of the most fascinating studies. Through continuous research, astronomers have found out several surprising facts about the universe and our solar system. Our solar system is ever evolving and newer facts are being discovered and studied by researchers year after year.

a) Rotation is like when you spin a top and it goes round and round while staying in one spot. The Earth also revolves around an imaginary line that goes through its centre. We can't see this line, so we call it imaginary. b) It is also known as Earth’s axis of rotation. c) It takes the Earth 24 hours, or one day, to complete a rotation. d) As the Earth rotates, different parts of it face the Sun, which gives us daylight. When your side of the Earth is facing away from the Sun, it's nighttime because it's dark.

Some key points about the rotation:
Axis: The axis is an imaginary straight line that goes through the centre of the Earth.
Poles: The North Pole and the South Pole are the two points on the Earth's surface where the axis comes out.
Solar Day: It takes Earth 24 hours to complete one full rotation, which we call a solar day.
How are Days and Nights Formed?
a) Day and night are formed because of the Earth’s rotation. b) As the Earth spins, one side of it faces the sun, and that's when it's day there. The sun shines on that side, and it's bright and sunny. c) But on the other side of the Earth, the part that's facing away from the sun, it's night there. It's dark because the sun is not shining on that side.

a) The Earth not only spins but also moves around the Sun in a fixed path called an orbit. This movement is called revolution. b) It takes the Earth 365 days, which we call a year, to complete one revolution around the Sun. This journey around the Sun is what gives us different seasons throughout the year. c) The Earth's tilt, about 23.5 degrees, also plays a role. It makes the different parts of the Earth face the Sun at different angles, which affects the seasons. That's why sometimes it's warmer and sunny, and other times it's cooler and darker.

There are two groups of planets in our solar system: the Terrestrial Planets and the Gas Giants.
![solar system essay for class 4 Diagram of the Solar System](https://www.crestolympiads.com/assets/images/science/solar-system4.png)
Terrestrial Planets
a) The Terrestrial Planets are also called the inner planets. They include Mercury, Venus, Earth, and Mars. b) These planets are the ones closest to the Sun. They are made up of lots of rocks and soil. Earth is one of these planets.
a) Gas Giants are also known as the outer planets of our solar system. They are Jupiter, Saturn, Uranus, and Neptune. b) They are really big and have a lot of gas in their atmosphere. It's like they are made up of fluffy clouds. Some of these planets, like Saturn, even have beautiful rings around them.
a) It's the smallest and closest planet to the Sun. b) It doesn't have any moons. c) It takes 88 days for Mercury to go around the Sun once.

a) It's the fifth planet from the Sun and the largest planet in the solar system. It is so big that it can fit all the other planets inside it. b) It rotates really fast, completing one rotation in 10 hours. c) Jupiter has a special feature called the Great Red Spot. It's like a gigantic storm that's been going on for a very long time. d) It's made mostly of gases. e) Jupiter has 95 moons.
a) It's the sixth planet from the Sun and the second largest planet. b) Saturn has beautiful rings made of rocks and ice. c) It has 146 moons.
a) It's the seventh planet from the Sun. b) It is very cold and windy. c) It's known as the sideways planet because of its unique feature of orbiting on its side. d) Uranus has 27 moons.
a) It's the eighth and farthest planet from the Sun. b) Neptune is icy, cold, and windy. c) It has the slowest revolution speed in the solar system. d) Neptune has 14 moons.
Why do Planets appear Bright?
a) The planets in our solar system appear bright because they are closer to us compared to the stars. b) Even though the planets are smaller than the stars, they look almost the same size as the stars because they are closer to us. c) Planets don't make their own light as stars do. Instead, they reflect the light from the Sun, just like how Moon reflects sunlight. This is why planets seem steady and don't twinkle as stars do.
