Huamea

Huamea
Humea is a dwarf planet located in the Sol System and is the 10th object from its host star with its neighboring dwarf planets being Pluto and Make-Make. Huamea is an interesting dwarf planet with its being in a strange oval shape instead of a being rounded like all the other trans-Neptunian objects. Huamea also has a visible ring system along with two small moons. Huamea's orbit is only slightly longer than Pluto's but is way colder with temperatures going as low as -400f.

Native Life
Just can't happen, way too cold.

Colonization
By the time of That One Reality not even a probe has been sent to Huamea and they still don't have a close up picture of it, plus the FOP has deemed Huamea too small for efficient colonization.
