Lipót Schulhof
Lipót Schulhof (12 March 1847 in Baja – October 1921 in Paris; hu, Schulhof Lipót; german: Leopold Schulhof or Schulhoff; french: Léopold Schulhof) was a Hungarian-JewishAron Moskovits, ''Jewish education in Hungary (1848-1948)'', p. 94 astronomer, born in the Austrian Empire, who first worked at the Vienna Observatory and later spent most of his time at the Paris Observatory, observing comets and asteroids. He provided a prediction for the 1893 return of comet 15P/Finlay, discovered the main-belt asteroid 147 Protogeneia in 1875, and was awarded the Lalande Prize of the French Academy of Sciences in 1893. Schulhof won the Lalande Prize again in 1920 for his calculation, assisted by Joseph Bossert, of the orbit of the periodic comet 12P/Pons–Brooks, discovered in 1812 by Pons. Schulhof calculated the orbits of many asteroids and comets, taking perturbative interactions into account. With his exhaustive studies of objects such as comet 27P/Crommelin and others, he ad ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

Lost Comet
A lost comet is one which was not detected during its most recent perihelion passage. This generally happens when data is insufficient to reliably calculate the comet's location or if the solar elongation is unfavorable near perihelion passage. The ''D/'' designation is used for a periodic comet that no longer exists or is deemed to have disappeared. Lost comets can be compared to lost asteroids ( lost minor planets), although calculation of comet orbits differs because of nongravitational forces, such as emission of jets of gas from the nucleus. Some astronomers have specialized in this area, such as Brian G. Marsden, who successfully predicted the 1992 return of the once-lost periodic comet Swift–Tuttle. Overview Loss There are a number of reasons why a comet might be missed by astronomers during subsequent apparitions. Firstly, cometary orbits may be perturbed by interaction with the giant planets, such as Jupiter. This, along with nongravitational forces, can result i ...

19th-century Hungarian Astronomers
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hungarian Jews
The history of the Jews in Hungary dates back to at least the Kingdom of Hungary, with some records even predating the Hungarian conquest of the Carpathian Basin in 895 CE by over 600 years. Written sources prove that Jewish communities lived in the medieval Kingdom of Hungary and it is even assumed that several sections of the heterogeneous Magyar tribes, Hungarian tribes practiced Judaism. Jewish officials served the king during the early 13th century reign of Andrew II of Hungary, Andrew II. From the second part of the 13th century, the general religious tolerance decreased and Hungary's policies became similar to the treatment of the Jewish population in Western Europe. The Jews of Hungary were fairly well integrated into Hungarian society by the time of the First World War. By the early 20th century, the community had grown to constitute 5% of Hungary's total population and 23% of the population of the capital, Budapest. Jews became prominent in science, the arts and busine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collab ...

Marguerite Laugier
Marguerite Laugier (née Lhomme) (12 September 1896 – 10 June 1976) was a French astronomer active at the Nice Observatory from the 1930s to the 1950s. Contemporary astronomical articles refer to her as "Madame Laugier". The Minor Planet Center credits her with the discovery of 21 numbered asteroids, made between 1932 and 1955. In 1939, she was awarded the Lalande Prize for her work. The outer main-belt asteroid 1597 Laugier, discovered by Louis Boyer at Algiers in 1949, is named in her honor (). ''Note:'' She is not to be confused with a male "M. Laugier" in 19th century literature, where the M. stands for "Monsieur". This refers to Paul Auguste Ernest Laugier Paul-Auguste-Ernest Laugier (22 December 1812, in Paris – 5 April 1872) was a French astronomer, one of two French astronomers referred to as M. Laugier.
