Earth (aka Terra) is the third planet orbiting the Sun, an average yellow-dwarf star near the outer rim of the Milky Way galaxy, and is the only known planet that supports life. It has a single, very large natural satellite referred to as "the Moon".
Earth figures prominently as the homeworld of the human species in a great number of science-fiction stories, shows, movies, and books.
