Haumea is a dwarf planet and Trans-Neptunian object (orbits the sun after Neptune) in Sol. It was discovered in 2005 by astronomers Michael E. Brown, Chad Trujillo and David Rabinowitz of the United States, and J. L. Ortiz of Spain. What's special about Haumea is it has a very short day (rotates every 4 hours on its axis), and this shaped it like an ellipsoid.
Haumea is named after the Hawaiian goddess of fertility and childbirth. It has two moons Hi'iaka and Namaka.
