Frédéric Sy
Frédéric Sy (1861-1917) was a French astronomer and a discoverer of minor planets. He worked at the Paris Observatory from 1879 to 1887, and as the assistant astronomer at the Algiers Observatory, North Africa, from 1887 to 1918. While working in Algiers he published extensively on the subjects of minor asteroids and comets, and was a colleague of astronomer François Gonnessiat. Sy was responsible for the discovery and naming of two asteroids, 858 El Djezaïr and 859 Bouzaréah. The names were drawn from locations near the discovering Algiers Observatory. He was awarded the Valz Prize ''(Prix Valz)'' in 1919 by the French Academy of Sciences. The asteroid 1714 Sy was named after him in 1951.

CRAAG - Bouzareah
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.

French Academy Of Sciences
The French Academy of Sciences (, ) is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the academy), it is one of the five Academies of the . __TOC__ History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationale, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the academy's existence were relatively informal, since no statutes had as yet been laid down for the ins ...

19th-century French Astronomers
The 19th century began on 1 January 1801 (represented by the Roman numerals MDCCCI), and ended on 31 December 1900 (MCM). It was the 9th century of the 2nd millennium. It 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, expanded beyond its British homeland for the first time during the 19th century, particularly remaking the economies and societies of the Low Countries, France, 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 Catholic Church, in response to the growing influence and power of modernism, secularism and materialism, formed the First Vatican Council in the late 19th century to deal with such problems and confir ...

Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful, "portal". In sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and involves providing new reasoning to explain the knowledge gathered through such observations, using knowledge previously acquired through abstract thought and from everyday experiences. Some discoveries represent a radical breakthrough in knowledge or technology. Others are based on earlier discoveries, collaborations or ideas. In such cases, the process of discovery requires at least the awareness that an existing concept or method could be modified or transformed. New discoveries are made using various senses, and are usually added to pre-existing knowledge. Questioning plays a key role in discovery; discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. Science Within scientific discip ...

1714 Sy
1714 Sy, provisional designation , is a stony asteroid from the central regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 25 July 1951, by French astronomer Louis Boyer at Algiers Observatory in Algeria, North Africa, and named after French astronomer and orbit computer Frédéric Sy. Orbit ''Sy'' orbits the Sun in the central main-belt at a distance of 2.2–3.0  AU once every 4 years and 1 month (1,503 days). Its orbit has an eccentricity of 0.15 and an inclination of 8 ° with respect to the ecliptic. It was first identified as at Goethe Link Observatory in 1948, extending the body's observation arc by 3 years prior to its official discovery observation at Algiers. Physical characteristics PanSTARRS large-scale survey characterized ''Sy'' as a L-type asteroid, a rare subtype which falls into the broader complex of stony S-type asteroids. Diameter and albedo According to the survey carried out by NASA's Wide-field ...

Valz Prize
The Valz Prize ''(Prix Valz)'' was awarded by the French Academy of Sciences, from 1877 through 1970, to honor advances in astronomy. History The Valz Prize was established in June 1874 when the widow of astronomer Benjamin Valz, Marie Madeleine Julie Malhian, donated 10,000 francs to establish a prize in honor of her late husband. The Valz Prize was to be awarded for work of similar stature as that honored by the pre-existing Lalande Prize. The first Valz Prize was awarded in 1877 to brothers Paul and Prosper Henry, and was for the sum of 460 francs. Save for 1924, the French Academy of Sciences awarded the Valz Prize annually from 1877 to 1943. After 1943, the prize was awarded only sporadically (only once per decade from 1950 to 1970). In 1970, the Valz Prize was combined with the Lalande Prize to create the Lalande-Valz Prize, which continued to be awarded through 1996. In 1997, that prize was combined with numerous other Academy prizes to create the Grande Médaille. List ...

Asteroid
An asteroid is a minor planet—an object larger than a meteoroid that is neither a planet nor an identified comet—that orbits within the Solar System#Inner Solar System, inner Solar System or is co-orbital with Jupiter (Trojan asteroids). Asteroids are rocky, metallic, or icy bodies with no atmosphere, and are broadly classified into C-type asteroid, C-type (carbonaceous), M-type asteroid, M-type (metallic), or S-type asteroid, S-type (silicaceous). The size and shape of asteroids vary significantly, ranging from small rubble piles under a kilometer across to Ceres (dwarf planet), Ceres, a dwarf planet almost 1000 km in diameter. A body is classified as a comet, not an asteroid, if it shows a coma (tail) when warmed by solar radiation, although recent observations suggest a continuum between these types of bodies. 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 ...
