Luboš Kohoutek
Luboš Kohoutek (; 29 January 1935 – 30 December 2023) was a Czech astronomer and a discoverer of minor planets and comets, including Comet Kohoutek which was visible to the naked eye in 1973. He also discovered a large number of planetary nebulae. Biography Kohoutek was born on 29 January 1935 to Hynek and Jarmila Kohoutek. His brother was the Czech composer Ctirad Kohoutek. Kohoutek was interested in astronomy since high school. He studied physics and astronomy at universities in Brno and Prague (finished 1958). Then he started to work in the Astronomical Institute of Czechoslovak Academy of Sciences, where he published a well-cited catalogue (''Catalogue of Galactic Planetary Nebulae'', 1967). Kohoutek obtained a long term position at the Bergedorf Observatory in Hamburg. After the Warsaw Pact invasion of Czechoslovakia, Soviet occupation of Czechoslovakia (1968) he decided to stay in West Germany (1970). His discoveries in the 1970s made him well-known in the media.

West Germany
West Germany was the common English name for the Federal Republic of Germany (FRG) from its formation on 23 May 1949 until German reunification, its reunification with East Germany on 3 October 1990. It is sometimes known as the Bonn Republic after its capital city of Bonn, or as the Second German Republic. During the Cold War, the western portion of Germany and the associated territory of West Berlin were parts of the Western Bloc. West Germany was formed as a political entity during the Allied occupation of Germany after World War II, established from 12 States of Germany, states formed in the three Allied zones of occupation held by the United States, the United Kingdom, and France. At the onset of the Cold War, Europe was divided between the Western and Eastern Bloc, Eastern blocs. Germany was divided into the two countries. Initially, West Germany claimed an exclusive mandate for all of Germany, representing itself as the sole democratically reorganised continuation of ...

C/1973 E1 (Kohoutek)
Comet Kohoutek (pronounced "" , or "" ), formally designated as C/1973 E1, 1973 XII and 1973f, is a comet that passed close to the Sun towards the end of 1973. Early predictions of the comet's peak brightness suggested that it had the potential to become one of the brightest comets of the 20th century, capturing the attention of the wider public and the press and earning the comet the moniker of "Comet of the Century". Although Kohoutek became rather bright, the comet was ultimately far dimmer than the optimistic projections: its apparent magnitude peaked at only –3 (as opposed to predictions of roughly magnitude –10) and it was visible for only a short period, quickly dimming below naked-eye visibility by the end of January 1974. The comet was discovered by and named after Luboš Kohoutek at the Hamburg Observatory on 18 March 1973; Kohoutek had been searching for Biela's Comet and had serendipitously discovered his eponymous comet while reviewing photographic plates for ...

Supernova
A supernova (: supernovae or supernovas) is a powerful and luminous explosion of a star. A supernova occurs during the last stellar evolution, evolutionary stages of a massive star, or when a white dwarf is triggered into runaway nuclear fusion. The original object, called the ''progenitor'', either collapses to a neutron star or black hole, or is completely destroyed to form a diffuse nebula. The peak optical luminosity of a supernova can be comparable to that of an entire galaxy before fading over several weeks or months. The last supernova directly observed in the Milky Way was Kepler's Supernova in 1604, appearing not long after Tycho's Supernova in 1572, both of which were visible to the naked eye. The supernova remnant, remnants of more recent supernovae have been found, and observations of supernovae in other galaxies suggest they occur in the Milky Way on average about three times every century. A supernova in the Milky Way would almost certainly be observable through mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1850 Kohoutek
1850 Kohoutek, provisional designation , is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was named after Czech astronomer Luboš Kohoutek. Discovery ''Kohoutek'' was discovered during World War II on 23 March 1942, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany, Ten days prior to its discovery, the body was observed at Turku Observatory, Finland. However, these observations are not considered for the asteroid's orbital computation and its observation arc begins with the discovery observation at Heidelberg. Since the discovery was made in the second half of March, the letter "E" in the provisional designation is erroneous. It should have been "F", but the initially incorrect assignment has persisted. Classification and orbit It is a member of the Flora family, one of the largest families of stony asteroids in the asteroid belt. It orbits the Sun in the inner main-belt at ...

Main-belt
The asteroid belt is a torus-shaped region in the Solar System, centered on the Sun and roughly spanning the space between the orbits of the planets Jupiter and Mars. It contains a great many solid, irregularly shaped bodies called asteroids or minor planets. The identified objects are of many sizes, but much smaller than planets, and, on average, are about one million kilometers (or six hundred thousand miles) apart. This asteroid belt is also called the main asteroid belt or main belt to distinguish it from other asteroid populations in the Solar System. The asteroid belt is the smallest and innermost circumstellar disc in the Solar System. Classes of small Solar System bodies in other regions are the near-Earth objects, the centaurs, the Kuiper belt objects, the scattered disc objects, the sednoids, and the Oort cloud objects. About 60% of the main belt mass is contained in the four largest asteroids: Ceres, Vesta, Pallas, and Hygiea. The total mass of the asteroid be ...

1865 Cerberus
1865 Cerberus is a stony asteroid and near-Earth object of the Apollo group, approximately 1.6 kilometers in diameter. It was discovered on 26 October 1971, by Czech astronomer Luboš Kohoutek at the Hamburger Bergedorf Observatory, Germany, and given the provisional designation . It was named for Cerberus from Greek mythology. Orbit and classification ''Cerberus'' orbits the Sun at a distance of 0.6–1.6 AU once every 1 years and 1 month (410 days). Its orbit has an eccentricity of 0.47 and an inclination of 16 ° with respect to the ecliptic. The Apollo asteroid has an ''Earth minimum orbital intersection distance'' of , which corresponds to 61 lunar distances. It passes within 30 gigametres ( Gm) of the Earth 7 times from the year 1900 to the year 2100, each time at a distance of 24.4 Gm to 25.7 Gm. It also makes close approaches to Mars and Venus.

Apollo Asteroid
The Apollo asteroids are a group of near-Earth asteroids named after 1862 Apollo, discovered by German astronomer Karl Reinmuth in the 1930s. They are Earth-crossing asteroids that have an orbital semi-major axis greater than that of the Earth (a > 1 AU) but perihelion distances less than the Earth's aphelion distance (q < 1.017 AU). , the number of known Apollo asteroids is 21,083, making the class the largest group of near-Earth objects (''cf''. the Aten, Amor and Atira asteroids), of which 1,742 are [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteroid
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 Solar System#Inner Solar System, 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 asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), 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 astronomical unit, AU ...

76P/West–Kohoutek–Ikemura
76P/West–Kohoutek–Ikemura is a Jupiter-family periodic comet in the Solar System with a current orbital period of 6.47 years. Discovery and observations The comet was initially spotted on a photographic plate by Richard M. West at the European Southern Observatory Sky Atlas Laboratory, Geneva in January 1975, when it had a brightness of magnitude 12. Inability to predict its movement from a single image meant the comet had to be presumed lost. In late February it was accidentally rediscovered by Lubos Kohoutek at the Hamburg Observatory, Germany and independently on 1 March by Toshihiko Ikemura in Shinshiro, Japan. After further observations the comets parabolic orbit was computed, which gave a perihelion date of 23 March 1975 and proved that all three sightings were of the same object, which was accordingly designated 76P/West–Kohoutek–Ikemura. The comet has been observed at its successive returns in 1987, 1993, 2000, 2006 and 2013. Orbit Further calculations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
75D/Kohoutek
75D/Kohoutek is a short-period comet discovered in February 1975, by Luboš Kohoutek. Even on the discovery plate the comet was only apparent magnitude 14. Assuming the comet has not disintegrated the 2020-2021 perihelion passage is only expected to peak around apparent magnitude 20. Not to be confused with the much better-known C/1973 E1 (Kohoutek), 75D is a repeat visitor to the inner Solar System, with a period of about seven years. It was placed on the discovery orbit when it passed from Jupiter on 28 July 1972. Apparitions have been dim, with the brightest being in 1988 at about apparent magnitude 13. It was not seen in 1994, 2000, 2007, nor on its last predicted return in 2014. The comet has been estimated to be in diameter. This comet was last observed by Mauna Kea on 19 May 1988. The Minor Planet Center has given the comet a "D/" designation as the comet is believed to be lost. The comet is calculated to come to opposition in October 2020 in the constellation of Pis ...
