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.
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. They are thought to be part of its extended collisional ...
Haumea (mythology) 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. Haumea is one of the most important Hawaiian gods, and her worship is among the oldest on the Hawaiian ...
Namaka (moon) In this photo taken by the Hubble Space Telescope, Namaka is the faint spot near the bottom, directly below Haumea (center). 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.
Apparent magnitude. 20.3 (3.0 difference from primary's 17.3) [3] 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 ...
Haumea family. The collisional family of Haumea (in green), other classical KBO (blue), Plutinos and other resonant objects (red) and SDO (grey). Radius is semi-major axis, angle orbital inclination. The Haumea or Haumean family is the only identified trans-Neptunian collisional family; that is, the only group of trans-Neptunian objects (TNOs ...
Michael E. Brown (born June 5, 1965) is an American astronomer, who has been professor of planetary astronomy at the California Institute of Technology (Caltech) since 2003. [1] His team has discovered many trans-Neptunian objects (TNOs), including the dwarf planet Eris, which was originally thought to be bigger than Pluto, triggering a debate ...
Haumea possesses a ring system, two known moons named Hiʻiaka and Namaka, and rotates so quickly (once every 3.9 hours) that it is stretched into an ellipsoid. It is part of a collisional family of Kuiper belt objects that share similar orbits, which suggests a giant impact on Haumea ejected fragments into space billions of years ago. [211]
