Some astronomers called Eris our Solar System's tenth planet when it was first discovered. After a lot of discussion, astronomers decided to make up a new category for objects like Eris. That is where the idea of dwarf planets came from.
The planet, re-classified as a dwarf planet along with Pluto, was named Eris on September 13, 2006 by the International Astronomical Union. The moon, named Shamlicht by Erisians, was officially named Dysnomia after Eris' daughter, the daemon of lawlessness.he dwarf planet Eris was discovered by the Palomar Observatory-based team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005, from images taken on October 21, 2003. The discovery was announced on July 29, 2005.
