136199 Eris is a dwarf planet in the Kuiper Belt. Eris was found in 2003 and given the temporary names "2003 UB313" and "Xena". It was later changed to Eris and it is the farthest known Dwarf Planet.

Eris has an even more tilted orbit than those of Ceres, (10 degrees), Pluto (17 degrees) and Makemake (28 degrees). Its orbit is inclined at a whooping 44 degrees similar to that of Tyche (which also has 44 degree orbit) and is so tilted that it crosses the orbits of Makemake and Pluto.


It was named after the goddess of strife and discord, because of the debate it caused about whether or not Pluto should be considered a planet. Before it was formally named, it was nicknamed Xena.
