Planets

Planets are the bodies which do not have their own light. As a result, they receive light from the sun and reflect that light. Moreover, with the help of this phenomena one can distinguish between planets and stars, that is planets do not twinkle, whereas, stars twinkle. Also, stars in the sky remains at same position whereas, planets change their positions.
In our solar system, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Among these, Mercury is the closest planet whereas, Neptune is farthest planet to the sun. Also, the planets like Mercury, Venus, Earth and Mars are much nearer to the sun. hence, they are called inner planets. These planets have few satellites. Planets like Jupiter, Saturn, Uranus and Neptune are at farther distance from inner planets hence, these are called outer planets. Moreover, these planets have one or more rings around them with large number of satellites.
