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.
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 ...
Haumea: The bodies included in this table are: (1) planemos; (2) major planets, dwarf planets, or moons of major or dwarf planets, or stars; (3) hydrostatically round so as to be able to provide a geodetic datum line.
The dwarf planet Haumea appears to be almost entirely made of rock, with only a superficial layer of ice; most of the original icy mantle is thought to have been blasted off by the impact that spun Haumea into its current high speed of rotation, where the material formed into the small Kuiper belt objects in Haumea's collisional family. There ...
Russian President Vladimir Putin and North Korean leader Kim Jong Un signed an agreement Wednesday that pledges mutual aid if either country faces “aggression,” a strategic pact that comes as ...
In 2023, Emery et al. wrote that near-infrared spectroscopy by the James Webb Space Telescope (JWST) in 2022 suggests that Sedna, Gonggong, and Quaoar underwent internal melting, differentiation, and chemical evolution, like the larger dwarf planets Pluto, Eris, Haumea, and Makemake, but unlike "all smaller KBOs".
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.
1995 SM 55 is a member of the Haumea family. [3] It has the highest collisional velocity, a δv of 123.3 m/s, of all confirmed members. [19] Based on their common pattern of IR water-ice absorptions, neutral visible spectrum [20] and the clustering of their orbital elements, the other KBOs 1996 TO 66, 2002 TX 300, 2003 OP 32 and 2005 RR 43 all appear to be collisional fragments broken off of ...
