After knowing the meaning of the solar system that has been described above, here is an explanation of the composition of the solar system. Here are the details:
1. Sun
The solar system consists of the sun and everything that orbits around it, including planets, moons, asteroids, comets, and meteoroids. The sun is 93 million miles from the earth. Light from the sun takes only 8 minutes to reach the earth. The earth revolves around the sun in a slightly oval-shaped circle. We call this the earth orbit. The sun is just one of hundreds of billions of stars in the Milky Way Galaxy. The entire universe has at least 100 billion galaxies in it.
2. Inner Planet
a. Mercury
Mercury is the closest planet to the Sun. The planet is so close to the Sun that it only takes 88 days to complete its orbit and is much hotter than Earth.
b. Venus
Venus is the next planet from the Sun after Mercury. Like Earth, Venus has an atmosphere (air) around it, but it is much thicker than Earth and Venus is permanently covered in clouds. Venus is the hottest planet and has an average temperature of 460 ° C. It takes 225 days to orbit the Sun.
c. Earth
Earth is where humans live. Earth is made of rock and is the only planet where water is liquid. Other planets are too hot or too cold. Earth takes 365 days to orbit the Sun.
d. March
Mars is slightly smaller than Earth, but much further away. It used to have an atmosphere like Earth and Venus, but not much anymore. Mars is reddish in color and is sometimes called the ‘Red Planet’. Mars takes 687 days to complete its orbit from the Sun and the average temperature is -63 °C.

3. The Outer Planets
a. Jupiter
Jupiter is the largest planet in the Solar System. Jupiter is even 1,321 times bigger than Earth. This planet is made of gas and is one of the four ‘gas giants’. Jupiter is five times farther from the Sun than Earth and takes nearly 12 years to orbit the Sun.
b. Saturn
Saturn is famous for its rings. Saturn is the second largest planet in the Solar System and is one of the ‘gas giants’ like Jupiter. It takes 29.5 years to go around the Sun.
vs. Uranus
Uranus is one of the ‘gas giants’. You can fit 63 Earth-sized planets inside Uranus. Uranus takes 84 years to orbit the Sun and is the coldest planet, with an average temperature of -220°C.
d. Neptune
Neptune is the planet farthest from the Sun. It is 30 times the distance from the Sun to the Earth and it takes 165 years to go around the Sun. Neptune is the last of the four ‘gas giants’ and measures 58 times the volume of Earth.
4. Comet
Comets are objects of ice, dust, and rock fragments that pass through space leaving a tail of ice and dust in their wake. A comet can reach a diameter of 25 miles. Comets are celestial bodies that revolve around the sun in oval, parabolic, or hyperbolic orbits.
5. Meteorid
Meteoroids are small rocky or metallic objects in outer space. Meteoroids are significantly smaller than asteroids, and range in size from tiny grains to objects up to one meter wide. Objects smaller than this are classified as micrometeoroids or space dust. A meteor is the appearance of the path of a meteoroid falling into the Earth’s atmosphere.
6. Asteroid
Asteroids in general are Solar System objects consisting of igneous rock and metal minerals. The main asteroid belt lies between the orbits of Mars and Jupiter, 2.3 and 3.3 AU from the sun, thought to be the remnants of the Solar System’s formation material that failed to agglomerate under the influence of Jupiter’s gravity.
7. Satellite
Not everything in the solar system orbits directly around the sun. Satellites orbit around certain planets. A satellite is a moon, planet or machine that orbits a planet or star. Satellites are divided into two types, namely natural satellites and artificial satellites. Natural satellites, for example, the moon that revolves around the earth. Meanwhile, the artificial satellite is the Palapa satellite which is owned by Indonesia.
