Uppsala–DLR Asteroid Survey
The Uppsala–DLR Asteroid Survey (UDAS, also known as ''UAO–DLR Asteroid Survey'') is an astronomical survey, dedicated for the search and follow–up characterization of asteroids and comets. UDAS puts a special emphasis on near-Earth objects (NEOs) in co-operation and support of global efforts in NEO-research, initiated by the ''Working Group on Near-Earth Objects'' of the International Astronomical Union (IAU), and the Spaceguard Foundation. UDAS began regular observations in September 1999, with some test runs during 1998. Discoveries of NEOs are reported to the Minor Planet Center (MPC). It is a kind of follow-on programme to OCA-DLR Asteroid Survey, ODAS, which had to close due to lack of further financial support. It should also not be confused with the Uppsala–DLR Trojan Survey (UDTS), which was conducted a few years before UDAS was launched. UAO stands for Uppsala Astronomical Observatory, Uppsala, Sweden. DLR stands for the Deutschen Zentrum für Luft- und Raumfah ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Uppsala
Uppsala ( ; ; archaically spelled ''Upsala'') is the capital of Uppsala County and the List of urban areas in Sweden by population, fourth-largest city in Sweden, after Stockholm, Gothenburg, and Malmö. It had 177,074 inhabitants in 2019. Located north of the capital Stockholm, it is also the seat of Uppsala Municipality. Since 1164, Uppsala has been the ecclesiology, ecclesiastical centre of Sweden, being the seat of the Archbishop of Uppsala, Archbishop of the Church of Sweden. Uppsala is home to Scandinavia's largest cathedral – Uppsala Cathedral, which was the frequent site of the coronation of the Swedish monarch until the late 19th century. Uppsala Castle, built by King Gustav I of Sweden, Gustav Vasa, served as one of the royal residences of the Swedish monarchs, and was expanded several times over its history, making Uppsala the secondary capital of Sweden during its Swedish Empire, greatest extent. Today, it serves as the residence of the Governor of Uppsala County ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid Surveys
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type (carbonaceous), M-type (metallic), or S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. 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 a region known as the main asteroid belt. The total mass of all the asteroids combined is only 3% that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Surveys
An astronomical survey is a general map or image of a region of the sky (or of the whole sky) that lacks a specific observational target. Alternatively, an astronomical survey may comprise a set of images, spectra, or other observations of objects that share a common type or feature. Surveys are often restricted to one band of the electromagnetic spectrum due to instrumental limitations, although multiwavelength surveys can be made by using multiple detectors, each sensitive to a different bandwidth. Surveys have generally been performed as part of the production of an astronomical catalog. They may also search for transient astronomical events. They often use wide-field astrographs. Scientific value Sky surveys, unlike targeted observation of a specific object, allow astronomers to catalog celestial objects and perform statistical analyses on them without complex corrections for selection effects. In some cases, an astronomer interested in a particular object will find t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uppsala–ESO Survey Of Asteroids And Comets
The Uppsala–ESO Survey of Asteroids and Comets (UESAC) took place in 1992–1993. A large number of asteroids were investigated. Over 15,000 positions were detected, and orbits were calculated for 2500. The observations were taken at European Southern Observatory, ESO's La Silla Observatory site in Chile, with a total of 74 obtained photographic plates, and at the Anglo-Australian Observatory (Siding Spring Observatory) in Australia. Details were published in 1996. List of discovered minor planets The Minor Planet Center credits UESAC with the discovery of 1123 numbered minor planets. The discoveries range from the lowest numbered discovery, 6102 Visby, to the currently highest numbered body, . The given total also including and , which were separately credited to "Comets UESAC", while all other discoveries were credited to "UESAC". More minor planets may yet to be numbered and added to this list as their orbits are confirmed. See also * List o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Asteroid-discovering Observatories
The list of asteroid-discovering observatories contains a section for each observatory which has discovered one or more asteroids, along with a list of those asteroids. For each numbered asteroid, the Minor Planet Center lists one or more discoverers who have been given credit for the discovery. Sometimes these are individuals (by modern rules there can be no more than three co-discoverers), and sometimes the credit is given to an organization (for instance, Purple Mountain Observatory). Observatories Andrushivka Astronomical Observatory The Andrushivka Astronomical Observatory is a private observatory near Andrushivka in Zhytomyr oblast, Ukraine. The observatory has IAU observatory code A50. It has discovered the following asteroids: Bohyunsan Optical Astronomy Observatory The Korean Bohyunsan Optical Astronomy Observatory (BOAO), located at Mount Bohyeon near the city of Yeongcheon, is a member of the East-Asian Planet Search Network, an international collabor ...

Uppsala Astronomical Observatory
The Uppsala Astronomical Observatory (UAO), Astronomiska observatoriet i Uppsala) is the oldest astronomical observatory in Sweden. It was founded in 1741, though there was a professorial chair of astronomy at the University of Uppsala from 1593 and the university archives include lecture notes in astronomy from the 1480s. In the 18th century, Anders Celsius performed his research there and built the first observatory proper in 1741. Celsius got the university wikt:consistory, consistory to buy a large stone house of medieval origin in central Uppsala, where he had an observatory constructed on the rooftop. Celsius both worked and had his personal living quarters in the house. This observatory remained in use until the new observatory, now known as the "old observatory", was built in 1853. The Celsius house itself remains as one of few older buildings on a modern shopping street, but the observatory on the roof was demolished in 1857. In the 19th century Anders Jonas Ångström w ...

Uppsala–DLR Trojan Survey
The Uppsala–DLR Trojan Survey (UDTS, also known as ''UAO–DLR Trojan Survey'') is an astronomical survey to study the movements and locations of asteroids near Jupiter, which includes Jupiter trojans and other asteroids, which line-of sight are frequently blocked by the giant planet. The survey was carried out at the Uppsala Astronomical Observatory in Sweden, in collaboration with the German Aerospace Center (DLR). Principal investigators were the astronomers Claes-Ingvar Lagerkvist, Gerhard Hahn, Stefano Mottola, Magnus Lundström and Uri Carsenty. The Uppsala–DLR Trojan Survey, UDTS, should not be confused with its successor, the Uppsala-DLR Asteroid Survey (UDAS), which started shortly after the UDTS concluded. During the course of the survey, two telescopes were used at European Southern Observatory, ESO's La Silla Observatory, La Silla site in northern Chile. In fall of 1996, the ESO Schmidt telescope surveyed approximately 900 Square degree, deg2 at Jupiter's Lagrang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
