Eris is the most distant dwarf planet, located beyond the orbit of Neptune. It was discovered in 2005 and was originally classified as a planet. It is the second-largest dwarf planet discovered and it led to both it and Pluto’s demotion from planets to dwarf planets.

How cold is the dwarf planet Eris?

It has a highly eccentric orbit around the Sun, which causes its surface temperature to vary from -217 degrees Celsius to -243 degrees Celsius. Observations of Eris have led scientists to believe that it has frozen methane on its surface. At 2400 kilometers in diameter, Eris is slightly larger than Pluto.

Why is Eris so bright?

The bright surface of Eris is most likely composed of a nitrogen-rich ice mixed with frozen methane — as indicated by the object’s spectrum — coating the dwarf planet’s surface in a thin and very reflective icy layer less than one millimetre thick.
