François Gonnessiat
François Gonnessiat (May 22, 1856 (Nurieux-Volognat)–October 18, 1934) was a French astronomer, observer of comets and discoverer of two minor planets. He worked at the Observatory of Lyon. In 1889 he won the Lalande Prize for astronomy from the French Academy of Sciences; 1901 became director of the Quito (Ecuador) Observatory for the purpose of making geodetic measurements. He became a well known and respected member of the academic scene of the city, where a street is named after him. From 1908 to 1931, he was director of the Algiers Observatory where one of his colleagues was Benjamin Jekhovsky. He was also director of the Quito Astronomical Observatory. The asteroid 1177 Gonnessia 1177 Gonnessia, provisional designation , is a dark background asteroid from the outer regions of the asteroid belt, approximately 99 kilometers in diameter.

Asteroid
An asteroid is a minor planet of the Solar System#Inner solar system, 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 astronomical unit, AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type asteroid, C-type, M-type asteroid, M-type, and S-type asteroid, 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 (dwarf planet), 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 slig ...

Algiers Observatory
The Algiers Observatory was built in the late 19th century in the Algiers suburb of Bouzaréah, Algeria, North Africa. It participated in the Astrographic Catalogue project, taking the zone between -2 and +4 degrees to expose 1,260 plates between the years 1891 and 1911. At the tail end of that time, the director of the installation was François Gonnessiat. It is now known as the Centre de Recherche en Astronomie Astrophysique et Géophysique (CRAAG), where it combines astronomy with work in astrophysics, and geophysical research, including the monitoring of earthquakes.

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, col ...

Herget's Discovery Circumstances
Paul Herget (January 30, 1908 – August 27, 1981) was an American astronomer and director of the Cincinnati Observatory, who established the Minor Planet Center after World War II. Career Herget taught astronomy at the University of Cincinnati. He was a pioneer in the use of machine methods, and eventually digital computers, in the solving of scientific and specifically astronomical problems (for example, in the calculation of ephemeris tables for minor planets). During World War II he applied these same talents to the war effort, helping to locate U-boats by means of the application of spherical trigonometry. Herget established the Minor Planet Center at the university after the war in 1947. He was also named director of the Cincinnati Observatory. The Minor Planet Center was eventually relocated in 1978 to the Smithsonian Astrophysical Observatory in Cambridge, Massachusetts, where it still operates. Awards and honors * In 1965 he was awarded the James Craig Watson ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1177 Gonnessia

Benjamin Jekhovsky
Benjamin Jekhowsky ( ru , Вениамин Павлович Жеховский, born 1881 in Saint-Petersburg (Russia), died in 1975, Encausse-les-Thermes (France)) was a Russian–French astronomer, born in Saint-Petersburg in a noble family of a Russian railroad official. After attending Moscow University, he worked at the Paris Observatory beginning in 1912. Later he worked at the Algiers Observatory (at the time, Algeria was a colony of France), where he became known as a specialist in celestial mechanics. After 1934, he appears to have begun signing scientific articles as Benjamin de Jekhowsky. The Minor Planet Center credits his discoveries under the name "B. Jekhovsky" (with a ''v''). In modern English transliteration, his name would be written as Zhekhovskii or Zhekhovsky. He discovered 12 numbered minor planets, made more than 190 scientific publications and the asteroid 1606 Jekhovsky Sixteen or 16 may refer to: *16 (number), the natural number following 15 and pr ...
