Alfred Schmitt
Alfred Schmitt (30 November 1907 – 2 April 1973) was a French astronomer. Schmitt worked at Algiers Observatory in the 1930s and 1940s and at the Royal Observatory in Uccle, Belgium in the 1950s. From 1955 to 1958 he was also director of the Quito Observatory in Ecuador. He extensively studied minor planets and comets and is credited with having discovered four asteroids. Personal life Between 1940 and 1948 he married his colleague, astronomer Odette Bancilhon and thereafter she signed her work as ''O. Schmitt-Bancilhon''. Signature Schmitt's publications are all signed A. Schmitt, following the practice of his profession at that time. Boyer In 1932, Schmitt discovered an asteroid while working at the Algiers Observatory and named it in honor of his colleague, Louis Boyer – asteroid 1215 Boyer 1215 Boyer, provisional designation , is a stony Eunomian asteroid from the central region of the asteroid belt, approximately 20 kilometers in diameter. It was discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Odette Bancilhon
Odette Bancilhon (22 September 1908 – 1998) was a French astronomer. She is best known for her work during the 1930s and 1940s at the Algiers Observatory, in Algeria, North Africa, where she discovered 1333 Cevenola, a stony Eunomian asteroid from the main-belt. Life and work Bancilhon was a graduate in science and she served as a meteorological assistant in Algiers for one year beginning 1 December 1932. On 7 December 1933, she was appointed as Alfred Schmitt's replacement while he performed his military service. In that capacity, in 1934, she discovered the asteroid (1333) Cevenola. (All of her publications at that time were signed ''O. Bancilhon'', a practice of her profession.) She was named an assistant on 1 November 1937. She married her colleague Alfred Schmitt in Algiers on 12 September 1942, and became known professionally as ''O. Schmitt-Bancilhon''. She and her husband were transferred to the Strasbourg Observatory in France on 1 January 1950, and she worked ther ... [...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 ...

Jet Propulsion Laboratory
The Jet Propulsion Laboratory (JPL) is a federally funded research and development center and NASA field center in the City of La Cañada Flintridge, California, United States. Founded in the 1930s by Caltech researchers, JPL is owned by NASA and managed by the nearby California Institute of Technology (Caltech). The laboratory's primary function is the construction and operation of planetary robotic spacecraft, though it also conducts Earth-orbit and astronomy missions. It is also responsible for operating the NASA Deep Space Network. Among the laboratory's major active projects are the Mars 2020 mission, which includes the ''Perseverance'' rover and the '' Ingenuity'' Mars helicopter; the Mars Science Laboratory mission, including the ''Curiosity'' rover; the InSight lander (''Interior Exploration using Seismic Investigations, Geodesy and Heat Transport''); the ''Mars Reconnaissance Orbiter''; the ''Juno'' spacecraft orbiting Jupiter; the ''SMAP'' satellite for earth surface s ...

Louis Boyer (astronomer)
Louis Boyer (1901–1999) was a French astronomer who worked at the Algiers Observatory, North Africa, where he discovered 40 asteroids between 1930 and 1952. In the 1950s and 1960s. he worked on identifications of small Solar System bodies at Nice Observatory in southeastern France. The asteroid 1215 Boyer, discovered by his colleague Alfred Schmitt at Algiers in 1932, was named after him. In turn Boyer named the 1617 Alschmitt asteroid in honor of Schmitt. Boyer also named 1713 Bancilhon after Odette Bancilhon his colleague and wife of astronomer Alfred Schmitt.

1215 Boyer
1215 Boyer, provisional designation , is a stony Eunomian asteroid from the central region of the asteroid belt, approximately 20 kilometers in diameter. It was discovered by astronomer Alfred Schmitt in 1932, who named it after French astronomer and college Louis Boyer. Discovery ''Boyer'' was discovered on 19 January 1932, by French astronomer Alfred Schmitt at the Algiers Observatory in Algeria, North Africa. Eight days later, it was independently discovered by Karl Reinmuth at Heidelberg Observatory in Germany. The body's observation arc begins at Algiers with its official discovery observation. Classification and orbit ''Boyer'' is a member of the Eunomia family (), the most prominent family in the intermediate main-belt, which mostly consists of stony asteroids. Conversely, ''Boyer'' has also been grouped into the Maria family (). It orbits the Sun at a distance of 2.2–2.9 AU once every 4 years and 2 months (1,512 days).
