Eris is the largest dwarf planet[1]. Discovered in 2003 by astronomers at the California Institute of Technology, it is the most distant object ever seen in orbit around the Sun. Little is known about Eris.
Eris has a highly elliptical orbit and takes 560 E-y to go around the Sun—more than twice the time it takes Pluto. Its inclination is steep, tilted at 44° to the planetary plane. It also has an extremely eccentric orbit. It will be at its closest, actually coming inside par of Pluto’s orbit, in about 280 E-y.
As of yet, nothing is known about Eris’s atmosphere, however, it may be similar to Pluto’s.
Eris, with a surface covered in frozen methane, may be similar to Pluto and the Neptunian moon Triton. Observations made by the Hubble Space Telescope show Eris’s surface is almost white and uniform, reflecting 86 percent of the light that hits it. This makes it the most reflective body in the Solar System. The dwarf planet’s interior is likely a mixture of rock and ice.
Eris has one moon. It is officially called S/2005 (2003 UB313) 1. Unofficially, it is referred to as Gabrielle. Little is known about this object.
These are some comparison pictures.
This is so you can keep everything in perspective.
