A dwarf planet that until 2006 was classified as the ninth planet in the Solar System. Pluto was not discovered until 1930, when Clyde Tombaugh noticed it while searching for an unknown planet thought to influence Uranus's orbit. Pluto's surface is covered with frozen methane and other ices, and its extremely thin atmosphere consists primarily of methane and nitrogen. Between 1979 and 1999 Pluto crossed inside Neptune's orbit. Pluto has three moons: Charon (discovered in 1978) and Hydra and Nix (both discovered in 2005).
(Greek mythology) the god of the underworld in ancient mythology; brother of Zeus and husband of Persephone
