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.

Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday experiences. Some discoveries represent a radical breakthrough in knowledge or technology. Others are based on earlier discoveries, collaborations or ideas. In such cases, the process of discovery requires at least the awareness that an existing concept or method could be modified or transformed. New discoveries are made using various senses, and are usually added to pre-existing knowledge. Questioning plays a key role in discovery; discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. Science Within scientific discip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vincenzo Zappalà
Vincenzo Zappalà (born 1945) is an Italian astronomer and discoverer of several main-belt asteroids. He is credited by the Minor Planet Center with the discovered of 9 minor planets. All of his discoveries he made at ESO's Chilean La Silla Observatory in 1984, with the exception of 17357 Lucataliano, which he discovered at Mount Stromlo Observatory in 1978. He has also been a long-term astronomer at the Observatory of Turin in Pino Torinese. Awards and honors The main-belt asteroid 2813 Zappalà, discovered by American astronomer Edward Bowell Edward L.

Minor Planet Circulars
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 coll ...

Edward Bowell
Edward L. G. "Ted" Bowell (born 1943 in London, died August 21 2023 in Flagstaff, Arizona), was an American astronomer. Bowell was educated at Emanuel School London, University College, London, and the University of Paris. He was principal investigator of the Lowell Observatory Near-Earth-Object Search (LONEOS). He has discovered a large number of asteroids, both as part of LONEOS and in his own right before LONEOS began. Among the latter are the Jovian asteroids 2357 Phereclos, 2759 Idomeneus, 2797 Teucer, 2920 Automedon, 3564 Talthybius, 4057 Demophon, and 4489 Dracius. He also co-discovered the periodic comet 140P/Bowell-Skiff and the non-periodic comet C/1980 E1. The outer main-belt asteroid 2246 Bowell was named in his honor. The official naming citation was published on 1 January 1981 (). List of discovered minor planets Edward Bowell discovered 571 minor planets. References External links Edward "Ted" Bowell , Lowel ...

Belgrade Observatory
The Belgrade Observatory is an astronomical observatory located in the Zvezdara Forest in the eastern part of Belgrade, Serbia. History Origin (1887–1891) In 1879, Milan Nedeljković (1857–1950) received a scholarship to continue his education in Paris at the Sorbonne. He studied mathematics and at the College de France extraordinary studying physics. In Paris Observatory was formed the first School of Astronomy, which Nedeljkovic successfully completed. During the study he also finished courses in meteorology, precision mechanics and seismology. After five years of study in Paris, he returned in 1884 in Belgrade where he became a professor of astronomy and meteorology at the Grand School (University of Belgrade). At the same time launching a campaign for the establishment of observatory at Grand School, but was rejected because of financial circumstances. Finally, after three long years, the decree of the founding of the Observatory was signed on by the Minister of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
3176 Paolicchi
3176 Paolicchi, provisional designation , is a carbonaceous asteroid from the outer region of the asteroid belt, about 34 kilometers in diameter. It was discovered on 13 November 1980, by Serbian astronomer Zoran Knežević at the Konkoly Observatory's Piszkéstető Station northeast of Budapest, Hungary. Orbit and classification The dark C-type asteroid orbits the Sun in the outer main-belt at a distance of 2.8–3.0 AU once every 4 years and 11 months (1,781 days). Its orbit has an eccentricity of 0.03 and an inclination of 18 ° with respect to the ecliptic. First identified as at Heidelberg Observatory in 1902, the first used observation was made at the U.S. Lowell Observatory in 1931, when ''Paolicchi'' was identified as , extending its observation arc by 49 years prior to its official discovery observation. Physical characteristics It has a rotation period of 20.400 hours and an albedo in the range of 0.04–0.08, according to the surveys carried out by the I ...

Asteroid Families
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An asteroid family is a more specific term than asteroid group whose members, while sharing some broad orbital characteristics, may be otherwise unrelated to each other. General properties Large prominent families contain several hundred recognized asteroids (and many more smaller objects which may be either not-yet-analyzed, or not-yet-discovered). Small, compact families may have only about ten identified members. About 33% to 35% of asteroids in the main belt are family members. There are about 20 to 30 reliably recognized families, with several tens of less certain groupings. Most asteroid families are found in the main asteroid belt, although several family-like groups such as the Pallas family, Hungaria family, and the Phocaea family ...
