Vitold Tserasky
Vitold Karlovich Tserasky also spelled Witold Cerasky (Russian:Витольд Карлович Цераский; 9 May 1849 – 29 May 1925) was a Russian astronomer and inventor of astronomical tools and techniques. The asteroid 807 Ceraskia and the Lunar crater Tseraskiy are named after him. Tserasky was born in Slutsk, Minsk where his father of Polish–Lithuanian descent was a geography teacher. A visit of Donati's comet in 1858 sparked an interest in Tserasky and he joined Moscow University in 1867 where he spent time at the astronomical observatory . He joined the astronomical observatory as an assistant and made a trip in 1874 to Kyakhta to make observations on the transit of Venus frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk.

807 Ceraskia
807 Ceraskia ( ''prov. designation'': ''or'' ) is an elongated Eos asteroid from the outer regions of the asteroid belt. It was discovered on 18 April 1915, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany. The S-type asteroid has a rotation period of 7.4 hours and measures approximately in diameter. It was named after Belarusian–Soviet astronomer Vitold Cerasky (1849–1925). Orbit and classification ''Ceraskia'' is a core member the Eos family (), the largest asteroid family of the outer main belt consisting of nearly 10,000 known asteroids. It orbits the Sun in the outer asteroid belt at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,913 days; semi-major axis of 3.02 AU). Its orbit has an eccentricity of 0.07 and an inclination of 11 ° with respect to the ecliptic. The asteroid was first observed as at Heidelberg Observatory on 18 January 1909. The body's observation arc begins at Vienna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tseraskiy (crater)
Tseraskiy (Ceraski) is an impact crater on the Moon's Far side (Moon), far side, approximately in diameter. It is located to the north-northeast of the huge walled plain Planck (crater), Planck, and to the southeast of the crater Pauli (crater), Pauli. To the east-northeast of Tseraskiy is Crocco (crater), Crocco. This is an eroded crater formation and the outer rim has been steady worn down to a roughly circular ridge with rounded edges. This crater overlies an older crater along the southwest side. There is a small crater along the exterior of the rim to the northeast. The interior floor is relatively level and is marked by several small and tiny craterlets, particularly in the western half. In some publications name has been spelt as Ceraski. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Tseraskiy.

Slutsk
Slutsk ( officially transliterated as Sluck, be, Слуцк; russian: Слуцк; pl, Słuck, lt, Sluckas, Yiddish/Hebrew: סלוצק ''Slutsk'') is a city in Belarus, located on the Sluch River south of Minsk.

Comet Donati
:''There are three Donati comets: C/1855 L1 (a.k.a. 1855 II), C/1858 L1 (this one), and C/1864 R1 (a.k.a. 1864 I).'' Comet Donati, or Donati's Comet, formally designated C/1858 L1 and 1858 VI, is a long-period comet named after the Italian astronomer Giovanni Battista Donati who first observed it on June 2, 1858. After the Great Comet of 1811, it was the most brilliant comet that appeared in the 19th century. It was also the first comet to be photographed. The comet will not be seen on Earth for another 1600 years. Discovery and observations Donati first observed the comet on 2 June from the Florence Observatory: it was initially visible as a small nebula-like object of magnitude 7 near the "head" of Leo.Stoyan, ''Atlas of Great Comets'', CUP, 2015, p.126 By mid-August it had brightened sufficiently to be visible to the naked eye.BortleThe Bright Comet Chronicles harvard.edu, accessed 14-02-17 In September it passed into Ursa Major.

Kyakhta
Kyakhta (russian: Кя́хта, ; bua, Хяагта, Khiaagta, ; mn, Хиагт, Hiagt, ) is a town and the administrative center of Kyakhtinsky District in the Republic of Buryatia, Russia, located on the Kyakhta River near the Mongolia–Russia border.

Transit Of Venus
frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than three times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Karl Friedrich Zöllner
Johann Karl Friedrich Zöllner (8 November 1834, Berlin25 April 1882, Leipzig) was a German astrophysicist who studied optical illusions. He was also an early psychical investigator. Biography From 1872 he held the chair of astrophysics at Leipzig University. He wrote numerous papers on photometry and spectrum analysis in Poggendorff's '' Annalen'' and ''Berichte der k. sächsischen Gesellschaft der Wissenschaften'', two works on celestial photometry (''Grundzüge einer allgemeinen Photometrie des Himmels'', Berlin, 1861, 4to, and ''Photometrische Untersuchungen'', Leipzig, 1865, 8vo), and a curious book, ''Ueber die Natur der Cometen'' (Leipzig, 1872, 3rd ed. 1883). He discovered the Zöllner illusion where lines that are parallel appear diagonal. He also successfully proved Christian Doppler's theory on the effect of motion of the color of stars, and the resulting shift of absorption lines, via the invention of a very sensitive spectroscope which he named "Reversionspectros ...
