Eris

Eris
Eris is a dwarf planet located in the Sol System and is the 12th object from its host star and neighboring dwarf planets being Make-Make and Gong-Gong. Eris is the farthest out trans-Neptunian that has an official dwarf planet classification. Eris is believed to have a pure white surface, even whiter than snow. Eris also has the longest orbit out of any of the classified objects in the entire Solar System clocking in at about 558 Earth years. With all that at the time almost nothing is known about the tiny rock so far from the warmth of the sun.

Native Life
No.

Colonization
Unlike the other dwarf planets Humans have a interest for colonizing Eris as it can be used as a gateway to send probs and eventually Humans from the Kuiper belt into the Oort Cloud.
