Namaka
Namaka is the smaller, inner moon of the dwarf planet Haumea. It is named after Nāmaka, the goddess of the sea in Hawaiian mythology and one of the daughters of Haumea. Namaka is only 1.5% as bright as its parent dwarf planet Haumea and is about 0.05% its mass. If it turns out to have a similar albedo, it would be about 170 km in diameter. Photometric observations indicate that its surface is made of water ice. Namaka (moon) - Wikipedia, the free encyclopedia
