when was pluto discovered and who discovered it
Pluto Pluto was discovered by Clyde Tombaugh in 1930 and was originally considered to be the ninth planet from the Sun. After 1992, its status as a planet was questioned following the discovery of several objects of similar size in the Kuiper belt. In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term "planet" formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
Pluto (Disney) Disney has dealt with a certain amount of confusion concerning the fact that Pluto (an ordinary dog) is treated as a household pet while the anthropomorphic Goofy is treated as a human despite being of the same species. On their web site, it stated that "Goofy was originally created as Dippy Dawg" and "was created as a human character, as opposed to Pluto who was a pet, so [Goofy] walked upright and had a speaking voice".
