Eris was discovered by the Palomar Observatory-based team of Mike Brown, Chad Trujillo, and David Rabinowitz on January 5, 2005 (YOLD 3171), from images taken on October 21, 2003 (YOLD 3169). The discovery was announced on July 29, 2005 (YOLD 3171). She is a trans-Neptunian object (TNO) native to a region of space beyond the Kuiper belt known as the scattered disc. Eris has one moon, Dysnomia; recent observations have found no evidence of further satellites. The current distance from the Sun is 96.7 AU, roughly three times that of Pluto. With the exception of some comets the pair are the most distant known natural objects in the Solar System.

With the exception of some comets the pair are the most distant known natural objects in the Solar System. The dwarf planet was first called Planet X (a long-used name for a then unknown 10th planet), then nicknamed Xena after the character in the television show of the same name. The moon was nicknamed Gabriella after Xena's close companion. The show frequently featured the character of Discord (goddess Discordia).
