Haumea (minor-planet designation: 136108 Haumea) is a dwarf planet located beyond Neptune's orbit. [25] It was discovered in 2004 by a team headed by Mike Brown of Caltech at the Palomar Observatory, and formally announced in 2005 by a team headed by José Luis Ortiz Moreno at the Sierra Nevada Observatory in Spain, who had discovered it that year in precovery images taken by the team in 2003.
Animation of Haumea and its moons, imaged by Hubble in 2008. Hiʻiaka is the brighter object around Haumea (center), and Namaka is the dimmer object below. Scale diagram of Haumea, the ring, and orbits of its two moons. The dwarf planet Haumea has two known moons, Hiʻiaka and Namaka, named after Hawaiian goddesses.
Hiʻiaka is the larger, outer moon of the trans-Neptunian dwarf planet Haumea. It is named after one of the daughters of Haumea , Hiʻiaka , the patron goddess of the Big Island of Hawaii . It orbits once every 49.12 ± 0.03 d at a distance of 49 880 ± 198 km , with an eccentricity of 0.0513 ± 0.0078 and an inclination of 126.356 ± 0.064° .
Haumea (Hawaiian: [həuˈmɛjə]) is the goddess of fertility and childbirth in Hawaiian mythology. She is the mother of many important deities, such as Pele, Kāne Milohai, Kāmohoaliʻi, Nāmaka, Kapo, and Hiʻiaka. She was killed by Kaulu. Haumea is one of the most important Hawaiian gods, and her worship is among the oldest on the Hawaiian ...
Namaka is the smaller, inner moon of the trans-Neptunian dwarf planet Haumea. Discovered in 2005, it is named after Nāmaka, the goddess of the sea in Hawaiian mythology and one of the daughters of Haumea. Namaka is notable for its unusual, highly-perturbed orbit that is heavily influenced by the larger, outer moon Hi'iaka.
The first known natural satellite was the Moon, but it was considered a "planet" until Copernicus' introduction of De revolutionibus orbium coelestium in 1543. Until the discovery of the Galilean satellites in 1610 there was no opportunity for referring to such objects as a class.
Orbits of Haumea family members, sharing semimajor axes around 43 AU, and inclinations around 27°.. The dwarf planet Haumea is the largest member of the family, and the core of the differentiated progenitor; other identified members are the moons of Haumea and the Kuiper belt objects (55636) 2002 TX 300, (24835) 1995 SM 55, (19308) 1996 TO 66, (120178) 2003 OP 32, (145453) 2005 RR 43, (86047 ...
(307261) 2002 MS 4 (provisional designation 2002 MS 4) is a large trans-Neptunian object in the Kuiper belt, which is a region of icy planetesimals beyond Neptune.It was discovered on 18 June 2002 by Chad Trujillo and Michael Brown during their search for bright, Pluto-sized Kuiper belt objects at Palomar Observatory.
