(136199) Eris Trans-Neptunian Object

Discovered on 21 October 2003 by Brown, M. E., Trujillo, C. A., Rabinowitz, D. L. at Palomar.

Eris is the Greek goddess of discord and strife. She stirs up jealousy and envy to cause fighting and anger among men. At the wedding of Peleus and Thetis all the gods were invited with the exception of Eris, and, enraged at her exclusion, she spitefully caused a quarrel among the goddesses that led to the Trojan war.Naming citation (20061009/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
