CERGA
The CERGA Observatory (french: Centre de recherches en géodynamique et astrométrie; obs. code: 010) was a scientific department and astronomical station of the Côte d'Azur Observatory in southern France, where several asteroids were discovered during 1984–1993. Description CERGA included 28 researchers and as many engineers and technicians located on the Observatory sites of Nice, Grasse and Calern (Caussols). The scientific activities covered fields as diverse as fundamental astronomy, celestial mechanics, and space geodesy. CERGA was in charge of several observing facilities of the Lunar Laser Ranging experiment, for example, the lunar-laser ranging telescope and the two satellite laser stations. By nature the scientific activity involved the acquisition of data and their processing, a dedicated instrumental development and a close relationship with the more theoretical aspects in dynamics and observation modelling. CERGA was dissolved in 2004 when the parent Côt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Côte D'Azur Observatory
The Côte d'Azur Observatory (french: Observatoire de la Côte d'Azur, OCA) is a network of astronomical observatories throughout southern France. It originated in 1988 with the merger of two observatories: # Nice Observatory # Centre de recherches en géodynamique et astrométrie (CERGA) Cote d'Azure Observatory tested beam combining technology at CHARA array. Astronomers developed a theory about M-Type asteroids, that may be tested by the planned spacecraft ''Psyche''.

Year Of Establishment Missing
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the mean y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid Surveys
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Astronomy Institutes And Departments
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

OCA–DLR Asteroid Survey
The OCA–DLR Asteroid Survey (ODAS) was an astronomical survey to search for small Solar System bodies focusing on near-Earth objects in the late 1990s. This European scientific project was a collaboration between the French Observatoire de la Côte d'Azur (OCA) and the German Aerospace Center (DLR). The survey is credited for the discovery of one comet and more than 1000 minor planets during 1996–1999. Description ODAS operated in cooperation with a global effort regarding near-Earth objects that was begun by the "Working Group on Near-Earth Objects", a component of the International Astronomical Union. The project began October 1996 and ceased observations in April 1999 for a refurbishing. However the telescope has not been reopened since that time. Survey observations were made during the 15 days each month when moon light was at a minimum, during the first and last quarters of the lunar month. The operation used a 90 cm Schmidt telescope of the OCA at Calern, near ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 MPC collect ...

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 reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.
