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.
Spheroidal bodies typically have some polar flattening due to the centrifugal force from their rotation, and can sometimes even have quite different equatorial diameters (scalene ellipsoids such as Haumea). Unlike bodies such as Haumea, the irregular bodies have a significantly non-ellipsoidal profile, often with sharp edges.
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. These small moons were discovered in 2005, from observations of Haumea made at the large telescopes of the W. M. Keck Observatory in Hawaii. Haumea's moons are unusual in a number of ways.
5.5 TK, highest man-made temperature in thermal equilibrium as of 2015 (quark–gluon plasma from LHC collisions) [18] 10 TK, 100 microseconds after the Big Bang; 45–67 TK at collapsar of a gamma-ray burst; 300–900 TK at proton–nickel conversions in the Tevatron's Main Injector [clarification needed]
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 ...
This list consists of all types of TNO subgroups: classical Kuiper belt objects, also known as "cubewanos", the resonant trans-Neptunian objects with their main and higher-order resonant subgroups, the scattered disc objects (SDOs), and the extreme trans-Neptunian objects including the ESDOs, EDDOs, and sednoids, which have a semi-major axis of ...
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.
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.
