Eris is the most massive and second-largest TNO known in the Solar System. Eris was found in 2003 in the Kuiper belt and was given the temporary names "2003UB-313" and "Xena". In 2005, it was changed to Eris.
==Tilted Orbit==
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.
