A Terrestrial Planet is a planet with a compact, rocky surface, like the Earth's, and a density greater than 3 grams per cubic cm.[1] By comparison, water has a density of 1 gram per cubic cm. They are composed primarily of rock and metal, have a slow rate of rotation, no rings and few satellites.[2]
Within our Solar System the four innermost planets, Mercury, Venus, Earth and Mars are all terrestrial planets.
