CHF Peters
Christian Heinrich Friedrich Peters (September 19, 1813 – July 18, 1890) was a German–American university teacher and astronomer at the Litchfield Observatory of Hamilton College, New York, and a pioneer in the study and visual discovery of asteroids. His name is often given as . Biography He was born in Koldenbüttel in Schleswig, then part of Denmark but later part of Germany, and later studied under Carl Friedrich Gauss. His younger brother was the German explorer Wilhelm Peters. Peters spoke many languages and gravitated to Italy at the time of the Italian unification. His association with radical groups brought him to the attention of authorities, and he fled to the Ottoman Empire, where he became a government advisor. At the suggestion of the resident U.S. consul, he emigrated to the United States in 1854. In 1874, Peters headed a United States Naval Observatory expedition to Queenstown, New Zealand, to observe the Transit of Venus. The visit is marked with a pla ...

Koldenbüttel
Koldenbüttel ( North Frisian: ''Koolnbütel'', nds, Kombüddel, da, Koldenbøl, Koldenbyttel) is a municipality in the district of Nordfriesland, in Schleswig-Holstein, Germany. Geography und infrastructure Koldenbüttel lies in the Eider Treene-Losiny about 8 miles south of Husum and just west of Friedrichstadt at the confluence of the Eider and the Treene in the Marsh. Koldenbüttel applies as Eiderstedt's most eastern village. Until the Treene's damming up in 1570 the village was suspended by Storm surges from North Sea-water flowing in the Eider and the Treene. Now there is a road at the dike's top leading from Koldenbüttel to Friedrichstadt The Bundesstraße 202 runs through the town; it connects the village with Friedrichstadt. At the Railway Tönning-Husum, which was opened in 1854, there was a small train station called "Büttel". After finishing the "Marschbahn" this breakpoint was closed down because of a central train station in Friedrichstadt. History Kol ...

100007 Peters
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Simon Newcomb
Simon Newcomb (March 12, 1835 – July 11, 1909) was a Canadian–American astronomer, applied mathematician, and autodidactic polymath. He served as Professor of Mathematics in the United States Navy and at Johns Hopkins University. Born in Nova Scotia, at the age of 19 Newcomb left an apprenticeship to join his father in Massachusetts, where the latter was teaching. Though Newcomb had little conventional schooling, he completed a BSc at Harvard in 1858. He later made important contributions to timekeeping, as well as to other fields in applied mathematics, such as economics and statistics. Fluent in several languages, he also wrote and published several popular science books and a science fiction novel. Biography Early life Simon Newcomb was born in the town of Wallace, Nova Scotia. His parents were John Burton Newcomb and his wife Miriam Steeves. His father was an itinerant school teacher, and frequently moved in order to teach in different parts of Canada, particularly in N ...

Galaxy
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek ' (), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System. Galaxies, averaging an estimated 100 million stars, range in size from dwarfs with less than a hundred million stars, to the largest galaxies known – supergiants with one hundred trillion stars, each orbiting its galaxy's center of mass. Most of the mass in a typical galaxy is in the form of dark matter, with only a few percent of that mass visible in the form of stars and nebulae. Supermassive black holes are a common feature at the centres of galaxies. Galaxies are categorized according to their visual morphology as elliptical, spiral, or irregular. Many are thought to have supermassive black holes at their centers. The Milky Way's central black hole, known as Sagittarius A*, has a mass four million times greater than the Sun. As o ...

Nebula
A nebula ('cloud' or 'fog' in Latin; pl. nebulae, nebulæ or nebulas) is a distinct luminescent part of interstellar medium, which can consist of ionized, neutral or molecular hydrogen and also cosmic dust. Nebulae are often star-forming regions, such as in the "Pillars of Creation" in the Eagle Nebula. In these regions, the formations of gas, dust, and other materials "clump" together to form denser regions, which attract further matter, and eventually will become dense enough to form stars. The remaining material is then thought to form planets and other planetary system objects. Most nebulae are of vast size; some are hundreds of light-years in diameter. A nebula that is visible to the human eye from Earth would appear larger, but no brighter, from close by. The Orion Nebula, the brightest nebula in the sky and occupying an area twice the angular diameter of the full Moon, can be viewed with the naked eye but was missed by early astronomers. Although denser than the space ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
80P/Peters–Hartley
80P/Peters–Hartley is a periodic comet in the Solar System with an orbital period of 8.12 years. It was originally discovered by Christian Heinrich Friedrich Peters of Capodimonte Observatory, Naples, Italy. There was insufficient data to accurately compute the orbit, and the comet was lost for well over a hundred years. It was accidentally rediscovered by Malcolm Hartley at the UK Schmidt Telescope Unit, Siding Spring, Australia on a photographic plate exposed on 11 July 1982. He estimated its brightness at a magnitude of 15. The sighting was confirmed by the Perth Observatory, where M. C. Candy calculated the orbit and concluded that Hartley had indeed relocated the lost Peter's comet. I. Hasegawa and Syuichi Nakano had simultaneously reached the same conclusion. It was observed at its next apparition in 1990 by R. H. McNaught of the Siding Spring observatory, who described as diffuse with a brightness of magnitude 14. It was subsequently observed in 1998, 2006 and 2014. S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Periodic Comet
Periodic comets (also known as short-period comets) are comets with orbital periods of less than 200 years or that have been observed during more than a single perihelion passage (e.g. 153P/Ikeya–Zhang). "Periodic comet" is also sometimes used to mean any comet with a periodic orbit, even if greater than 200 years. Periodic comets receive a permanent number prefix usually after the second perihelion passage, which is why there are a number of unnumbered periodic comets, such as P/2005 T5 (Broughton). Comets that are not observed after a number of perihelion passages, or presumed to be destroyed, are given the D designation, and likewise comets given a periodic number and subsequently lost are given instead of , such as 3D/Biela or 5D/Brorsen. In nearly all cases, comets are named after their discoverers, but in a few cases such as 2P/Encke and 27P/Crommelin they were named for a person who calculated their orbits (the orbit computers). The long-term orbits of comets ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

72 Feronia
72 Feronia (minor planet designation: 72 Feronia) is a quite large and dark main belt asteroid. It was the first asteroid discovery by C. H. F. Peters, on May 29, 1861, from Hamilton College, New York State. It was initially thought that Peters had merely seen the already known asteroid 66 Maja, but T.H. Safford showed that it was a new body. Safford named it after Feronia, a Roman fertility goddess. This asteroid is orbiting the Sun with a period of , having a semimajor axis of and an eccentricity of 0.121. The orbital plane is inclined by an angle of 5.4° to the plane of the ecliptic. This is a spectral type TDG asteroid with a cross-section size of 84 km. The asteroid has an estimated rotation period of 8.09 h. Hanuš et al. (2013) gives two possible solutions for the pole in ecliptic coordinates: (λ1, β1) = (287°, −39°) or (λ1, β1) = (102°, −55°). The estimated mass of 72 Feronia, and hence the density, has a large margin of error. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clinton, Oneida County, New York
Clinton (or ''Ka-dah-wis-dag'', "white field" in Seneca language) is a village in Oneida County, New York, United States. The population was 1,942 at the 2010 census. It was named for George Clinton, the first Governor of New York. The Village of Clinton, site of Hamilton College, is within the Town of Kirkland. The village was known as the "village of schools" due to the large number of private schools operating in the village during the 19th century. History Part of Coxe's Patent, 6th division, Clinton began in March 1787 when Revolutionary War veterans from Plymouth, Connecticut, settled in Clinton. Pioneer Moses Foote brought seven other families with him to the area. The new inhabitants found good soil, plentiful forests, and friendly Brothertown Indians in southern Kirkland along with Oneida people, who passed through on trails. Named after New York's first governor, George Clinton, an uncle of Erie Canal builder and governor DeWitt Clinton, the village had a gri ...
