Is é Hiʻiaka uimhir 98 de réadanna an Grianchórais in ord a méid. Tá trastomhas de níos lú ná 420 km aige. S'é an ceann is mó dé'n dhá shatailít a bhfuil i bhfithis thart ar an abhacphláinéad Haumea. S'é Namaka an t-ainm atá ar an ghealach níos lú eile.

- ↑ Quotation: The Hiʻiaka density of 0.685±0.134 g/cm3 reported by Vara Lubiano in 2023 uses the outdated Hiʻiaka mass of (1.8±0.1)×1019 kg from 2009. Proudfoot et al. (2024) measured a lower mass for Hiʻiaka, which means the density of Hiʻiaka is must also be lower, if one uses Vara Lubiano's diameter measurement. Dividing the Proudfoot et al.'s (2024) mass by the volume calculated from Vara Lubiano's mean sphere-equivalent diameter gives a density of 461 ± 149 kg/m3 (0.461 ± 0.149 g/cm3) (uncertainties calculated via propagation of error)..
