This is Haumea, one of five dwarf planets identified in our solar system. She is too small to have a proper global atmosphere, so gravity has pulled her into an egg shape. She spins so fast that her day lasts just 3.9 hours. And to cap it all, something collided with her and now she has a big red bruise on one side and a ring of ice and rock she just can't seem to shake off.

A day on Haumea is about four Earth hours. It takes 285 Earth years for Haumea to orbit the Sun. Haumea's radius is about 385 miles or 620 kilometers. Haumea has two known moons: Namaka is the inner moon, and Hi'iaka.
