how did pluto the dog get his name
Pluto (Disney) Several months had passed between the naming of what was believed to be the ninth planet, Pluto, on March 24, 1930, and the attachment of that name to the dog character. Venetia Burney (later Venetia Phair), who as an eleven-year-old British schoolgirl had suggested the name Pluto for the planet, remarked in 2006: "The name had nothing to do with the Disney cartoon. Mickey Mouse's dog was named after the planet, not the other way around."[12] Although it has been claimed that Disney named the dog after the planet, rather than after the mythical god of the underworld, this has not been verified. Disney animator Ben Sharpsteen said "We thought the name [Rover] was too common, so we had to look for something else. ... We changed it to Pluto the Pup ... but I don't honestly remember why."[13] Disney says they have no documents to support or refute the connection.[14][not in citation given] Unofficially, even Disney's animators believed that Walt Disney chose the name to capitalize on the sensation of the newly named planet.[15]
Moons of Pluto The dwarf planet Pluto has five moons down to a detection limit of about 1 km in diameter. In order of distance from Pluto, they are Charon, Styx, Nix, Kerberos, and Hydra.[1] Charon, the largest of the five moons, is mutually tidally locked with Pluto, and is massive enough that Pluto–Charon is sometimes considered a double dwarf planet.
