 Eris is one of the most important known dwarf planets in our system. It's about an equivalent size as Pluto but is 3 times farther from the Sun.

Eris first seemed to be larger than Pluto. This triggered a debate within the scientific community which led the International Astronomical Union to change the decision in 2006 to clarify the definition of a planet. Pluto, Eris, and other similar objects are now classified as dwarf planets.

This Dwarf planet is named after a Greek goddess of discord and strife.
