José Luis Ortiz Moreno
José Luis Ortiz Moreno (born 1967) is a Spanish astronomer, and former vice director of Technology at the Instituto de Astrofísica de Andalucía (IAA), Spain. He leads a team working on minor planets at the Sierra Nevada Observatory in Granada, Spain. The main-belt asteroid 4436 Ortizmoreno was named in his honor. Discovery of Haumea On July 29, 2005, Ortiz announced the discovery of , provisional designation , one of the few officially recognized dwarf planets of the Solar System. This led to a controversy over who to credit for the discovery: Michael E. Brown and his team at Caltech had also been observing Haumea, and for a longer period of time than Ortiz, but had withheld publication pending securing its orbital parameters. Brown initially supported Ortiz and his team being given credit for the discovery, but withdrew that support when it turned out that Ortiz had accessed Brown's public observation logs and research just before announcing the discovery.

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting IAU definition of planet, reclassified minor planets and comets into dwarf planets and Small Solar System body, small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006. Accessed May 5, 2008. In contrast to the eight official planets of the Solar System, all minor planets fail to clearing the neighborhood, clear their orbital neighborhood.

Orbital Parameters
Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems using a Kepler orbit. There are many different ways to mathematically describe the same orbit, but certain schemes are commonly used in astronomy and orbital mechanics. A real orbit and its elements change over time due to gravitational Perturbation (astronomy), perturbations by other objects and the effects of general relativity. A Kepler orbit is an idealized, mathematical approximation of the orbit at a particular time. When viewed from an inertial frame, two orbiting bodies trace out distinct trajectories. Each of these trajectories has its Focus (geometry), focus at the common center of mass. When viewed from a non-inertial frame centered on one of the bodies, only the trajectory of the opposite body is apparent; Keplerian elements describe these non-inertial trajectories. An orbit has two sets of Keplerian elements depe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Haumea (dwarf Planet)
Haumea (minor-planet designation: 136108 Haumea) is a dwarf planet located trans-Neptunian object, beyond Neptune's orbit. It was discovered in 2004 by a team headed by Michael E. Brown, Mike Brown of California Institute of Technology, 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. From that announcement, it received the provisional designation 2003 EL61. On 17 September 2008, it was named after Haumea (mythology), Haumea, the Hawaiian goddess of childbirth and fertility, under the expectation by the International Astronomical Union (IAU) that it would prove to be a dwarf planet. Nominal estimates make it the List of Solar System objects by size, third-largest known trans-Neptunian object, after Eris (dwarf planet), Eris and Pluto, and approximately the size of Uranus's moon Titania (moon), Tita ...

Minor Planet Center
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the ...

How I Killed Pluto And Why It Had It Coming
''How I Killed Pluto and Why It Had It Coming'' is the 2010 memoir by Mike Brown, the American astronomer most responsible for the reclassification of Pluto from planet to dwarf planet. Summary The memoir is an account of the events surrounding the redefinition of the term ''planet'' that eventually changed the status of Pluto. It chronicles the discovery of Eris, a dwarf planet then mistakenly thought to be larger than Pluto, located within the scattered disc, beyond Neptune's orbit. The replaying of events includes the adversarial challenging of long-held scientific beliefs between some of the world's leading astronomers and the eventual 2006 International Astronomical Union's vote that removed Pluto from the list of Solar System planets. Reviews Reviews of the book have been generally positive, with James Kennedy of ''The Wall Street Journal'' calling the book a "brisk" and "enjoyable ... chronicle" of the tale of the search for new planets and the eventual demotion of ...

Ataecina
Ataegina (; ) was a goddess worshipped by the ancient Iberians, Lusitanians, and Celtiberians of the Iberian Peninsula. She is believed to have ruled the underworld. Names The deity's name is variously attested as ''Ataegina'', ''Ataecina'', ''Adaecina'' and ''Adaegina'', among other spellings. Her name appears in conjunction to a place named ''Turibriga'' or ''Turobriga'' (see below). Etymology Celtic hypothesis The name ''Ataegina'' is most commonly derived from a Celtic source: according to Cristina Maria Grilo Lopes and Juan Olivares Pedreño, French scholar D'Arbois de Jubainville and Portuguese scholar José Leite de Vasconcelos interpreted her name as a compound from ''*ate-'' 'repetition, re-' ''*-genos'' '(to be) born'. Thus, her name would mean 'The Reborn One' ("renascida", in the original).Lopes, Cristina Maria Grilo.Ataegina uma divindade Paleohispânica. In: ''Revista Santuários''. Lisboa, 2014.

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ...

Caltech
The California Institute of Technology (branded as Caltech) is a private university, private research university in Pasadena, California, United States. The university is responsible for many modern scientific advancements and is among a small group of Institute of Technology (United States), institutes of technology in the United States that are devoted to the instruction of pure and applied sciences. The institution was founded as a preparatory and vocational school by Amos G. Throop in 1891 and began attracting influential scientists such as George Ellery Hale, Arthur Amos Noyes, and Robert Andrews Millikan in the early 20th century. The vocational and preparatory schools were disbanded and spun off in 1910, and the college assumed its present name in 1920. In 1934, Caltech was elected to the Association of American Universities, and the antecedents of NASA's Jet Propulsion Laboratory, which Caltech continues to manage and operate, were established between 1936 and 1943 under ...
