Haumea (pronounced how-MAY-uh) is a dwarf planet in the Kuiper belt, making it a plutoid. It is one-third as massive as Pluto. It is very probably shaped as an ellipsoid despite having collapsed under its own gravity into an equilibrium shape (a requirement for a dwarf planet); the non-spherical shape is due to the unknown but extremely rapid rate of rotation. An estimate of its dimensions is 1960 × 1518 × 996 kilometers.
