Dwarf-system satellite

Hiʻiaka

Haumea’s larger outer moon in a fast-spinning, elongated system.

Hiʻiaka orbits beyond Namaka and contributes to one of the most dynamically unusual dwarf-planet systems. Its brighter icy surface stands apart from the dark background of the Kuiper belt.

System portrait

The outer member of a complex family

Hiʻiaka’s period, separation and inclination are shown in the parent-equatorial context used by the scene, without inventing missing angular elements.

System geometry

Hiʻiaka around Haumea

Hiʻiaka orbits at a mean distance of 49,880 km with a period of 49.462 days. Its catalogued eccentricity is 0.051, and the catalogued inclination is 2° relative to Haumea equatorial plane. Missing angular orientation stays explicitly representative.

Representation notes

What Explore is showing

Published mean system scale and the 2° inclination to Haumea's equator are used. Missing node/periapsis orientation remains representative.
