Discovery of Namaka

30 June 2005

Namaka is the smaller of the two known moons of the dwarf planet Haumea, in the Kuiper belt, discovered on 30 June 2005 by the astronomers Michael Brown and colleagues using the Keck telescope in Hawaii. It is about 170 kilometers across and orbits Haumea in about eighteen days on an eccentric path, and its orbit is disturbed by the larger moon, Hiʻiaka. Like Haumea itself, it is mostly water ice, which suggests that the moons formed from debris after a giant collision. It is named after Namaka, a sea spirit and a daughter of Haumea in the mythology of Hawaii.
