Eris - Dwarf Planet and Kuiper Belt Object | KidsLearningTube

Eris is a dwarf planet discovered in 2005 by a team led by Michael Brown at the Celtic Observatory. It is the most massive known dwarf planet, with a surface believed to be covered in nitrogen ice. Officially named by the IAU in 2006, Eris is 27% more massive than Pluto but slightly smaller in size. It has one natural satellite named Dysnomia, meaning lawlessness. Eris takes 557 Earth years to orbit the sun, occasionally leaving the Kuiper belt. The average surface temperature is -390 degrees Fahrenheit, making it extremely cold.
