Haumea – Dwarf Planet

 

Haumea is the third closest dwarf planet to the Sun with a distance of 43 astronomical units. It was originally designated as 2003 EL61. On September 17th, 2008, it was classified as a dwarf planet by the International Astronomical Union (IAU). It takes 285 Earth years to make one trip around the Sun.

The rotation of this dwarf planet is so fast and because of this it has turned into an ellipsoid. It spins on its axis once every 3.9 hours. It is one of the fastest rotating large objects in our solar system.
