136108 Haumea           Discovered 2003 Mar. 7 at the Sierra Nevada Observatory.
Haumea is the goddess of childbirth and fertility in Hawaiian mythology. Her many children sprang from different parts of her body. She takes many different forms and has experienced many different rebirths. As the goddess of the earth, she represents the element of stone. The satellites (136108) Haumea I and II were discovered by M. E. Brown, A. H. Bouchez and the Keck Observatory Adaptive Optics teams. Haumea I, discovered 2005 Jan. 26, is named Hi'iaka, who was born from the mouth of Haumea and carried by her sister Pele in egg form from their distant home to Hawaii. Hi'iaka danced the first Hula on the shores of Puna and is the patron goddess of the island of Hawaii and of hula dancers. Haumea II, discovered 2005 Nov. 7, is named Namaka, for a water spirit in Hawaiian mythology. Namaka was born from the body of Haumea and is the sister of Pele. When Pele sends her burning lava into the sea, Namaka cools the lava to become new land.
