A number of names for the "tenth planet" were discussed; two popular ones were Xena, from the TV program, and Persephone, in Greek mythology the consort of Pluto. However, in 2006, the International Astronomical Union recategorized Pluto as a "dwarf planet", and the body tentatively named "Xena" was officially named Eris as another "dwarf planet". (There are three other named "dwarf planets" to go with Pluto and Eris.)
