Pluto is a planet, named in honor of the Roman god.
Pluto is Mickey Mouse's pet dog. Unlike most of Walt Disney's animated animal characters, Pluto does not talk, being "really" a dog. His face, however, is extraordinarily expressive.
PLUTO (Pipe-Lines Under The Oceans) was a major project undertaken during WW2 by the British scientists and armed forces to carry and deliver gasoline.
