136199 Eris (2003 UB313) is the second largest after 134340 Pluto and the most massive Dwarf planet in the solar system, and is a trans-Neptunian object in the scattered disc. Eris was discovered by Mike Brown at the Palomar Observatory in January 2005. There is a pre-discovery image from October 2003, but, it was not recognized due to its slow orbital motion.

Eris is named for Eris the Greek goddess of strife and discord.

Eris has one satellite, Dysnomia.
