Ou. Solar System !

A solar system is simply a sun and all the bodies around it that it controls by gravity. Out solar system is made up of all the planets, moons, asteroids, and comets that our sun controls by gravity. Out earth is simply one of the planets.

The planets vary greatly in size and distance from the sun. Mercury is the smallest planet and the nearest to the sun. It goes around the sun in only 88 days. Venus is about 68 million miles from the sun, and goes around it 225 days. The earth is 93 million miles from the sun. Mars is about 142 million miles from the sun and goes around it in 687 days.

Jupiter, which is about 483 million miles away from the sun, takes 12 years to make one trip around it. Saturn, 886 million miles form the sun, takes 29 1/2 years to make one orbit. Neptune takes 165 years. so you see, while these planets are part of out solar system, each one is quite different and exist under very different conditions.
