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.
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 ...
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 ...
Michael E. Brown Precovery images of Haumea were recorded as early as 1955 at the Palomar Observatory. On December 28, 2004, Mike Brown and his team discovered Haumea on images they had taken with the 1.3 m SMARTS Telescope from the Cerro Tololo Inter-American Observatory in Chile at the Palomar Observatory in the United States on May 6, 2004, while looking for what he hoped would be the tenth ...
One set is said to intersect another set if . Sets that do not intersect are said to be disjoint . The power set of X {\displaystyle X} is the set of all subsets of X {\displaystyle X} and will be denoted by ℘ ( X ) = def { L : L ⊆ X } . {\displaystyle \wp (X)~{\stackrel {\scriptscriptstyle {\text{def}}}{=}}~\{~L~:~L\subseteq X~\}.}
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 power set of the set of natural numbers can be put in a one-to-one correspondence with the set of real numbers (see Cardinality of the continuum). The power set of a set S, together with the operations of union, intersection and complement, is a Σ-algebra over S and can be viewed as the prototypical example of a Boolean algebra.
