Bisei Spaceguard Center
The Bisei Spaceguard Center (BSGC) is an astronomical observatory located at Bisei-chō, Okayama, Japan. The facility was constructed during 1999–2000, where it since conducts the Bisei Asteroid Tracking Telescope for Rapid Survey or , an astronomical survey that solely tracks asteroids and space debris. BATTeRS has discovered numerous minor planets and the periodic, Halley-type comet and near-Earth object C/2001 W2 (BATTERS). Space debris, along with defunct spaceships, satellites as well as other small objects can present a hazard to operating spacecraft. Built by the Japan Space Forum (JSF) with contributions by the Japanese Ministry of Education, Culture, Sports, Science and Technology, all expenses of the center are covered by the Japan Aerospace Exploration Agency (JAXA). The telescopes which keep track of any space debris are manned by members of the Japan Spaceguard Association. Besides the spaceguard center, the facility also includes the Bisei Astro ...

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.

Cassegrain Reflector
The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical path folds back onto itself, relative to the optical system's primary mirror entrance aperture. This design puts the focal point at a convenient location behind the primary mirror and the convex secondary adds a telephoto effect creating a much longer focal length in a mechanically short system. In a symmetrical Cassegrain both mirrors are aligned about the optical axis, and the primary mirror usually contains a hole in the center, thus permitting the light to reach an eyepiece, a camera, or an image sensor. Alternatively, as in many radio telescopes, the final focus may be in front of the primary. In an asymmetrical Cassegrain, the mirror(s) may be tilted to avoid obscuration of the primary or to avoid the need for a hole in the primary mirror (or both). The classic Cassegrain ...

Takeshi Urata
was a Japanese astronomer. He was a prolific discoverer of asteroids, observing at Nihondaira Observatory. In 1978 he became the first amateur to discover a minor planet (2090 Mizuho) in over fifty years, which he named after his daughter, Mizuho. His pioneering feat led to an upsurge in such discoveries. In the ten years that followed, amateurs from Japan discovered 160 minor planets. Urata shared his observation data with peer astronomers in Japan on a periodical called "Tenkai" (the Heavens), as well as contributed to academic journals such as ''Advances in Space Research'' and participated in poster presentations at astronomical conferences. Urata co-discovered the periodic comet 112P/Urata-Niijima in 1986. One of the most active amateur astronomers in Japan, he was also an editor of the Japanese ''Ephemerides of Minor Planets''. The 1927-discovered asteroid 3722 Urata is named after him. List of discovered minor planets References {{DEFAUL ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syuichi Nakano
is a Japanese astronomer. He specializes in the study of comets, in particular calculating their orbits and making predictions about when periodic comets will return for another perihelion approach. It is considerably more difficult to predict the orbits of comets than of other types of Solar System objects, since their orbits are susceptible not only to perturbations from the planets but also to non-gravitational forces due to the release of gaseous material in the form of a comet's coma and tail. He is affiliated with the Computing & Minor Planet Sections (Center for Astrodynamics) of the Oriental Astronomical Association in Sumoto, Japan. He publishes the ''Nakano Notes'' on comet observations and ephemerides. In 2001 he won the Amateur Achievement Award of the Astronomical Society of the Pacific. The asteroid 3431 Nakano is named after him, and asteroid 3983 Sakiko is named after his sister. 1026 Ingrid was reidentified in 1986 by Syuichi Nakano, ending its time as a l ...

David J
David John Haskins (born 24 April 1957, Northampton, Northamptonshire, England), better known as David J, is a British alternative rock musician, producer, and writer. He is the bassist for the gothic rock band Bauhaus and for Love and Rockets. He has composed the scores for a number of plays and films, and also wrote and directed his own plays, ''Silver for Gold (The Odyssey of Edie Sedgwick)'', in 2008, which was restaged at REDCAT in Los Angeles in 2011, and ''The Chanteuse and The Devil's Muse'' in 2011. His artwork has been shown in galleries internationally, and he has been a resident DJ at venues such as the Knitting Factory. David J has released a number of singles and solo albums, and in 1990 he released one of the first No. 1 hits on the then nascent Modern Rock Tracks charts, with "I'll Be Your Chauffeur".

Astrometric
Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy, the Milky Way. History The history of astrometry is linked to the history of star catalogues, which gave astronomers reference points for objects in the sky so they could track their movements. This can be dated back to Hipparchus, who around 190 BC used the catalogue of his predecessors Timocharis and Aristillus to discover Earth's precession. In doing so, he also developed the brightness scale still in use today. Hipparchus compiled a catalogue with at least 850 stars and their positions. Hipparchus's successor, Ptolemy, included a catalogue of 1,022 stars in his work the ''Almagest'', giving their location, coordinates, and brightness. In the 10th century, Abd al-Rahman al-Sufi carried out observations on the stars and described their positions, magnitu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
