434 Hungaria
Hungaria (minor planet designation: 434 Hungaria) is a relatively small asteroid orbiting in the inner asteroid belt. It is an E-type (high-albedo) asteroid. It is the namesake of the Hungaria asteroids, which orbit the Sun on the inside of the 1:4 Kirkwood gap, standing out of the core of the asteroid belt. It was discovered by Max Wolf on 11 September 1898 at the University of Heidelberg. It was named after Hungary, which hosted an astronomical meeting in 1898 in Budapest. It is thought that there may be a genetic connection between 434 Hungaria and 3103 Eger and the aubrites.

Max Wolf
Maximilian Franz Joseph Cornelius Wolf (21 June 1863 – 3 October 1932) was a German astronomer and a pioneer in the field of astrophotography. He was the chairman of astronomy at the University of Heidelberg and director of the Heidelberg-Königstuhl State Observatory from 1902 until his death in 1932. Early life Max Wolf was born in Heidelberg, Germany on 21 June 1863, the son of medical doctor Franz Wolf. His father encouraged an interest in science and built an observatory for his son in the garden of the family home. It is from here that Wolf was credited with his first astronomical discovery, comet 14P/Wolf, in 1884. Life at the university Wolf attended his local university and, in 1888, at the age of 25, was awarded a Ph.D. by the University of Heidelberg. He spent one year of post-graduate study in Stockholm, the only significant time he would spend outside of Heidelberg in his life. He returned to the University of Heidelberg and accepted the position of ''pri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aubrite
Aubrites are a group of meteorites named for Aubres, a small achondrite meteorite that fell near Nyons, France, in 1836. They are primarily composed of the orthopyroxene enstatite and are often called enstatite achondrites. Their igneous origin separates them from primitive enstatite achondrites and means they originated in an asteroid. Aubrites are typically light-colored with a brownish fusion crust. Most aubrites are heavily brecciated; they are often said to look "lunar" in origin. Aubrites are primarily composed of large white crystals of the Fe-poor, Mg-rich orthopyroxene, or enstatite, with minor phases of olivine, nickel-iron metal, and troilite, indicating a magmatic formation under extremely reducing conditions. The severe brecciation of most aubrites attests to a violent history for their parent body. Since some aubrites contain chondritic xenoliths, it is likely that the aubrite parent body collided with an asteroid of “F-chondritic” composition. Comparisons of au ...

E-type Asteroids (Tholen)
E-type asteroids are asteroids thought to have enstatite (MgSiO3) achondrite surfaces. They form a large proportion of asteroids inward of the asteroid belt known as Hungaria asteroids, but rapidly become very rare as the asteroid belt proper is entered. There are, however, some that are quite far from the inner edge of the asteroid belt, such as 64 Angelina. They are thought to have originated from the highly reduced mantle of a differentiated asteroid. Description E-type asteroids have a high albedo (0.3 or higher), which distinguishes them from the more common M-type asteroids. Their spectrum is featureless flat to reddish. Probably because they originated from the edge of a larger parent body rather than a core, E-types are all small, with only three (44 Nysa, 55 Pandora, 64 Angelina) having diameters above 50 kilometres and no others above 25 kilometers (the biggest three also orbit atypically far, c. 3 AU, from the Sun). Aubrites (enstatite achondrite meteorites) are belie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brian D
Brian (sometimes spelled Bryan in English) is a male given name of Irish and Breton origin, as well as a surname of Occitan origin. It is common in the English-speaking world. It is possible that the name is derived from an Old Celtic word meaning "high" or "noble". For example, the element ''bre'' means "hill"; which could be transferred to mean "eminence" or "exalted one". The name is quite popular in Ireland, on account of Brian Boru, a 10th-century High King of Ireland. The name was also quite popular in East Anglia during the Middle Ages. This is because the name was introduced to England by Bretons following the Norman Conquest. Bretons also settled in Ireland along with the Normans in the 12th century, and 'their' name was mingled with the 'Irish' version. Also, in the north-west of England, the 'Irish' name was introduced by Scandinavian settlers from Ireland. Within the Gaelic speaking areas of Scotland, the name was at first only used by professional families of Irish o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icarus (journal)
''ICARUS'' is a scientific journal dedicated to the field of planetary science. It is officially endorsed by the American Astronomical Society's Division for Planetary Sciences (DPS). The journal contains articles discussing the results of new research on astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of the Solar System or extrasolar systems. The journal was founded in 1962, and became affiliated with the DPS in 1974. Its original owner and publisher was Academic Press, which was purchased by Elsevier in 2000. The journal is named for the mythical Icarus, and the frontispiece of every issue contains an extended quotation from Sir Arthur Eddington equating Icarus' adventurousness with the scientific investigator who "strains his theories to the breaking-point till the weak joints gape."

7187 Isobe
7187 Isobe, provisional designation , is a likely binary Hungaria asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 30 January 1992, by American astronomer Eleanor Helin at Palomar Observatory in California, United States. It is named after Japanese astronomer Syuzo Isobe. Classification and orbit The presumed E-type asteroid is a member of the Hungaria family, which form the innermost dense concentration of asteroids in the Solar System. ''Isobe'' orbits the Sun in the inner main-belt at a distance of 1.8–2.1 AU once every 2 years and 8 months (985 days). Its orbit has an eccentricity of 0.09 and an inclination of 22 ° with respect to the ecliptic. It was first identified as at the discovery observatory in 1985, extending the body's observation arc by 7 years prior to its official discovery observation. According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1750 Eckert
1750 Eckert, provisional designation , is a stony slow rotating Hungaria asteroid and Mars-crosser from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 15 July 1950, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. It was named after American astronomer Wallace Eckert. Classification and orbit The Mars crossing asteroid is also a member of the Hungaria family, a group that forms the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.6–2.3 AU once every 2 years and 8 months (977 days). Its orbit has an eccentricity of 0.17 and an inclination of 19 ° with respect to the ecliptic. As no precoveries were taken, and no prior identifications were made, ''Eckert''s observation arc begins with its official discovery observation. Rotation period In October 2009, a rotational lightcurve of ''Eckert'' was obtained by American astronomer Bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1453 Fennia
1453 Fennia, provisional designation , is a stony Hungaria asteroid and synchronous binary system from the innermost regions of the asteroid belt, approximately 7 kilometers in diameter. Discovered by Yrjö Väisälä at the Turku Observatory in 1938, the asteroid was later named after the Nordic country of Finland. The system's minor-planet moon was discovered in 2007. It has a derived diameter of 1.95 kilometers and is orbiting its primary every 23.55 hours. Discovery ''Fennia'' was discovered on 8 March 1938, by Finnish astronomer Yrjö Väisälä at the Iso-Heikkilä Observatory in Turku, southwest Finland. Fifteen days later, it was independently discovered by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula, which also served as a confirmation of the first observation. The Minor Planet Center only recognizes the first discoverer. Orbit and classification ''Fennia'' is a bright member of the Hungaria asteroids, a dynamical group that ...
