Pluto
About
Considered a dwarf planet, it is named after the god of the underworld. The name of the planet inspired the name of the Disney cartoon dog Pluto, who was first introduced to audiences in the same year of Pluto's discovery.
Trivia
In the early 1990s, after several similarly-sized objects were discovered in the same belt as Pluto, the Kuiper belt, there was much debate as to whether Pluto should be classified as a planet or not. The public gained some clarity in 2006 when the International Astronomical Union released an official definition of the term "planet" and classified Pluto as a "dwarf planet."
