Haumea's moons are unusual in a number of ways. They are thought to be part of its extended collisional family, which formed billions of years ago from icy debris after a large impact disrupted Haumea's ice mantle. Hiʻiaka, the larger, outermost moon, has large amounts of pure water ice on its surface, which is rare among Kuiper belt objects. [1]

Mar 12, 2025 · Haumea has two known moons: Namaka is the inner moon, and Hi'iaka is the outer moon. Both were discovered in 2005 and named for the mythological daughters of Haumea.

Because Haumea has moons, the mass of the system can be calculated from their orbits using Kepler's third law. The result is 4.2 × 1021 kg, 28% the mass of the Plutonian system and 6% that of the Moon.

Apr 4, 2025 · Haumea, unusual dwarf planet orbiting the Sun in the Kuiper belt beyond Pluto. It was discovered in 2003 by a team of American astronomers at Cerro Tololo Inter-American Observatory. Originally called 2003 EL61, Haumea is named for the Hawaiian goddess of …

Haumea has two known moons: Namaka is the inner moon, and Hi'iaka is the outer moon. Both are named for the mythological daughters of Haumea.

The two moons of Haumea were discovered in 2005 by Darin Ragozzine and Michael Brown. They discovered the natural satellites using the W. M. Keck Observatory when observing the dwarf planet.

Jun 2, 2024 · Haumea’s two known moons are named after the goddess’ daughters—Hi’iaka and Namaka. Haumea is a dwarf planet, a plutoid located beyond Neptune. Haumea is thought to have been large enough to have been rounded by its own gravity into an orbiting shape in hydrostatic equilibrium.
