Our last dwarf planet, Eris is an icy world roughly the size of Pluto. It was classified as a dwarf planet in 2006.
Initially believed to be slightly larger than Pluto, Eris was thought by some to be the tenth planet of our solar system. A debate on the definition of a planet led to the new classification of dwarf planet.
Discovered in 2005, Eris is named after the Greek goddess of discord and strife.
Eris orbits the sun on a tilted, elliptical path. It travels from far outside the Kuiper Belt to inside of Pluto’s orbit in the Kuiper Belt.
Eris has one known moon. Dysnomia was named after the daughter of Eris in Greek mythology.
