Eris (dwarf planet)
Eris, formal designation 136199 Eris, is the largest known dwarf planet in the Solar System and the ninth-largest body known to orbit the Sun directly. It is approximately 2,500 kilometres in diameter and 27% more massive than Pluto.[9][12]
Eris w as first identified in January 2005 by a Palomar Observatory-based team led by Mike Brown, and its identity verified later that year. It 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,[10] 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.[2]
Because Eris is larger than Pluto, its discoverers and NASA called it the Solar System�s tenth planet. More
