Tatooine is a sandy planet controlled by the Hutts, a well renowned clan. Although it is ruled by this clan, it is well known for its trading, podracing, and poor standards. As stated by Qui Gon Jinn in Star Wars: Episode I: The Phantom Menace, it is a place where people do not want to be found.
Suprisingly, Tatooine is not always hot like in the day. At night, when its three moons come out, Tatooine itself becomes extremely cold.
