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.

1555 Dejan
1555 Dejan, provisional designation , is an asteroid from the background population of the central regions of the asteroid belt, approximately 22 kilometers in diameter. It was discovered on 15 September 1941, by Belgian astronomer Fernand Rigaux at the Royal Observatory of Belgium in Uccle. The asteroid was named after Dejan Đurković, son of Serbian astronomer Petar Đurković. Orbit and classification ''Dejan'' is a non-family asteroid from the main belt's background population. It orbits the Sun in the central asteroid belt at a distance of 1.9–3.4 AU once every 4 years and 5 months (1,610 days). Its orbit has an eccentricity of 0.28 and an inclination of 6 ° with respect to the ecliptic. The body's observation arc begins with its first identification as at Johannesburg Observatory in August 1932, more than 9 years prior to its official discovery observation at Uccle.

Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collab ...

Herget's Discovery Circumstances
Paul Herget (January 30, 1908 – August 27, 1981) was an American astronomer and director of the Cincinnati Observatory, who established the Minor Planet Center after World War II. Career Herget taught astronomy at the University of Cincinnati. He was a pioneer in the use of machine methods, and eventually digital computers, in the solving of scientific and specifically astronomical problems (for example, in the calculation of ephemeris tables for minor planets). During World War II he applied these same talents to the war effort, helping to locate U-boats by means of the application of spherical trigonometry. Herget established the Minor Planet Center at the university after the war in 1947. He was also named director of the Cincinnati Observatory. The Minor Planet Center was eventually relocated in 1978 to the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, where it still operates. Awards and honors * In 1965 he was awarded the James Craig Watson Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fernand Rigaux
Fernand Rigaux (1905 – 21 September 1962) was a Belgian astronomer and observer of variable stars, minor planets and comets at the Royal Observatory at Uccle, Belgium. In 1951, he co-discovered the periodic comet 49P/Arend-Rigaux with his colleague Sylvain Arend. He is also credited by the Minor Planet Center with the discovery of 8 asteroid An asteroid is a minor planet of the inner Solar System.

Belgrade Astronomical Observatory
Belgrade Observatory is an astronomical observatory located in the eastern part of Belgrade, Serbia, in the natural environment of Zvezdara Forest. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1605 Milankovitch
1605 Milankovitch, provisional designation , is an Eoan asteroid from the outer region of the asteroid belt, approximately 31 kilometers in diameter. It was named after Serbian scientist Milutin Milanković. Discovery ''Milankovitch'' was discovered on 13 April 1936, by Serbian astronomer Petar Đurković at the Royal Observatory of Belgium in Uccle, Belgium. Two nights later, the body was independently discovered by Polish astronomers Jan Piegza and Tadeusz Banachiewicz at Cracow and Warsaw, respectively. It was first identified as at the U.S. Taunton Observatory () in 1907. However, it remained unused – as did the subsequent observations at both Simeiz and Lowell Observatory in 1925 and 1931, respectively. The body's observation arc begins with its official discovery observation at Uccle in 1936. Orbit and classification ''Milankovitch'' is a member of the Eos family, an orbital group of more than 4,000 asteroids, which are well known for mostly being of stony compo ...
