Planets - Paperback

by Rebecca Woodbury (Author)

A planet is an object in space that orbits a star, is spherical, and is big enough to have its own gravity. Earth is one of 8 planets that orbit the Sun. There are two different types of planets. Terrestrial planets are Earth-like and made of rock. Mercury, Venus, Earth, and Mars are terrestrial planets and are closest to the Sun. Jovian planets are Jupiter-like and made of gas. Jupiter, Saturn, Uranus, and Neptune are Jovian planets and are farthest from the Sun. A moon is a natural object that orbits a planet. Earth has one moon, Mercury and Venus have no moons, and all the other planets have two or more moons. Each planet moves in its own orbit around the Sun. As far as we know, Earth is the only planet that supports life. Earth is the right distance from the Sun to have liquid water and the right temperatures and has air for living things to use.
