459 Signe
459 Signe, provisional designation , is a stony asteroid from the background population of the intermediate asteroid belt, approximately 26 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg-Königstuhl State Observatory on 22 October 1900. The asteroid was presumably named after Signy, a character of the Scandinavian Völsunga saga and Norse mythology. Signy is the daughter of Völsung and sister of Sigmund In Germanic mythology, Sigmund ( , ) is a hero whose story is told in the Völsunga saga. He and his sister, Signý, are the children of Völsung and his wife Hljod. Sigmund is best known as the father of Sigurð the dragon-slayer, though Sigu ....

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 Doctor of Philosophy, 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 ...

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 ...

Sigmund
In Germanic mythology, Sigmund ( , ) is a hero whose story is told in the Völsunga saga. He and his sister, Signý, are the children of Völsung and his wife Hljod. Sigmund is best known as the father of Sigurð the dragon-slayer, though Sigurð's tale has almost no connections to the Völsung cycle except that he was a dragonslayer. ''Völsunga saga'' In the ''Völsunga saga'', Signý marries Siggeir, the king of Gautland (modern Västergötland). Völsung and Sigmund are attending the wedding feast (which lasted for some time before and after the marriage), when Odin, disguised as a beggar, plunges a sword (Gram) into the living tree Barnstokk ("offspring-trunk"Orchard (1997:14).) around which Völsung's hall is built. The disguised Odin announces that the man who can remove the sword will have it as a gift. Only Sigmund is able to free the sword from the tree. Siggeir is smitten with envy and desire for the sword. He tries to buy it but Sigmund refuses. Siggeir invites ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Völsung
Völsung ( , ) is a figure in Germanic mythology, where he is the eponymous ancestor of the Völsung family (, ), which includes the hero Sigurð. In Nordic mythology, he is the son of Rerir and was murdered by the Geatish king Siggeir. He was later avenged by one of his sons, Sigmund, and his daughter Signy, who was married to Siggeir. Völsung's story is recorded in the Völsung Cycle, a series of legends about the clan. The earliest extant versions of the cycle were recorded in medieval Iceland; the tales of the cycle were expanded with local Scandinavian folklore, including that of Helgi Hundingsbane (which appears to originally have been part of the separate tradition of the Ylfings), and form the material of the epic poems in the Elder Edda and of , which preserves material from lost poems. Völsung is also the subject matter of the Middle High German epic poem and is referred to in the Old English epic ''Beowulf''. Name The Old English is composed of a suffix de ...

Völsunga Saga
The ''Völsunga saga'' (often referred to in English as the ''Volsunga Saga'' or ''Saga of the Völsungs'') is a legendary saga, a late 13th-century prose rendition in Old Norse of the origin and decline of the Völsung clan (including the story of Sigurd and Brunhild and the destruction of the Burgundians). It is one of the most famous legendary sagas and an example of a "heroic saga" that deals with Germanic heroic legend. The saga covers topics including the quarrel between Sigi and Skaði, a huge family tree of great kings and powerful conquerors, the quest led by Sigmund and Sinfjǫtli to save princess Signý from the evil king Siggeir, and, most famously, Sigurd killing the serpent/dragon Fáfnir and obtaining the cursed ring Andvaranaut that Fáfnir guarded. Context and overview The saga is largely based on the epic poetry of the historic '' Elder Edda''. The earliest known pictorial representation of this tradition is the Ramsund carving in Sweden, which was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heidelberg-Königstuhl State Observatory
Heidelberg-Königstuhl State Observatory () is a historic astronomical observatory located near the summit of the Königstuhl hill in the city of Heidelberg in Germany. It is operated by the ''Center for Astronomy (ZAH)'' at the University of Heidelberg. The predecessor of the current observatory was originally opened in 1774 in the nearby city of Mannheim but degradation of observational conditions there resulted in a relocation to the Königstuhl in 1898. The Observatory facility have little value for current astronomical research of ZAH; research is done with the Gama Ray H.E.S.S in Namibia and ESO facilitys in Chile. Andreas Quirrenbach is the observatory's director since 2005. History The instrumentation of the observatory originated from the Mannheim Observatory, founded in 1774. In 1880, the observatory was provisionally moved to Karlsruhe because the astronomical/atmospherical seeing conditions worsened. In subsequent years, three other locations were considered ...

Asteroid 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 body, small Solar System bodies in other regions are the near-Earth objects, the Centaur (minor planet), 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 (dwarf planet), C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-type Asteroid
S-type (stony-type or silicaceous-type) asteroids are asteroids with a spectral type that is indicative of a siliceous (i.e. stony) mineralogical composition, hence the name. They have relatively high density. Approximately 17% of asteroids are of this type, making it the second-most common after the carbonaceous C-type. Characteristics S-type asteroids, with an astronomical albedo of typically 0.20, are moderately bright and consist mainly of iron- and magnesium-silicates. They are dominant in the inner part of the asteroid belt within 2.2 AU, common in the central belt within about 3 AU, but become rare farther out. The largest are 3 Juno (about 240–250 km across) and 15 Eunomia (230 km), with other large S-types being 29 Amphitrite, 532 Herculina and 7 Iris. These largest S-types are visible in 10x50 binoculars at most oppositions; the brightest, 7 Iris, can occasionally become brighter than +7.0, which is a higher magnitude than any asteroid except ...
