Some astronomers called Eris our Solar System's tenth planet when it was first discovered. After a lot of discussion, astronomers decided to make up a new category for objects like Eris. That is where the idea of dwarf planets came from.
Eris (dwarf planet) Eris (IPA: [ËÉª.É¹Éªs] or [ËÉ.É¹Éªs] ), also designated (136199) Eris or 136199 Eris (See Minor planet names), is the largest known dwarf planet in the solar system and the ninth largest body orbiting the Sun.
