Hiiaka was the first satellite to be discovered around Haumea. It is named after on of the daughters of Haumea, Hiiaka, the patron goddess of the big island of Hawaii, or goddess of dance, though at first it had gone by the nickname 'Ruldolph' by its discovery team.
Namaka was nicknamed 'Blitzen' by the discovery team, before receiving an official name.
