Dwarf Planet Eris
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 kilometers in diameter and 27% more larger than Pluto.
Eris was first spotted in 2003 but not identified until 2005. It is a Trans Neptunion Object (TNO) native to a region of space beyond the Kuiper belt. Eris has one moon, Dysmonia. The current distance from the Sun is 96.7 AU, roughly three times that of Pluto. (8.9 billion miles from Earth) With the exception of some comets the pair are the most distant known natural objects in the Solar System.
This is my first image of Eris. Although it is very low resolution
I've included it so that you
may see the movement of Eris through 3 successive images taken over a week's time.

A single 5-minute exposure was taken before cloud rolled in, so this is a very
"noisy" image
