1181 Lilith
1181 Lilith ('' prov. designation:'' ) is a metallic asteroid from the middle region of the asteroid belt, approximately in diameter. It was discovered on 11 February 1927, by Russian–French astronomer Benjamin Jekhowsky at Algiers Observatory in Algeria, Northern Africa, and named after French composer Lili Boulanger. Classification and orbit ''Lilith'' is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements. It orbits the Sun in the middle asteroid belt at a distance of 2.1–3.2 AU once every 4 years and 4 months (1,587 days). Its orbit has an eccentricity of 0.20 and an inclination of 6 ° with respect to the ecliptic. First observed as at Simeiz Observatory in 1914, ''Lilith''s observation arc begins 7 years after its official discovery observation, with its first used observation made at Konkoly Observatory in 1934.

Asteroid Family
An asteroid family is a population of asteroids that share similar proper orbital elements, such as semimajor axis, eccentricity, and orbital inclination. The members of the families are thought to be fragments of past asteroid collisions. An asteroid family is a more specific term than asteroid group whose members, while sharing some broad orbital characteristics, may be otherwise unrelated to each other. General properties Large prominent families contain several hundred recognized asteroids (and many more smaller objects which may be either not-yet-analyzed, or not-yet-discovered). Small, compact families may have only about ten identified members. About 33% to 35% of asteroids in the main belt are family members. There are about 20 to 30 reliably recognized families, with several tens of less certain groupings. Most asteroid families are found in the main asteroid belt, although several family-like groups such as the Pallas family, Hungaria family, and the Phocaea family ...

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 Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lilith
Lilith ( ; he, Wiktionary:לילית, לִילִית, Līlīṯ) is a female figure in Mesopotamian Mythology, Mesopotamian and Jewish mythology, Judaic mythology, alternatively the first wife of Adam and supposedly the primordial she-demon. Lilith is cited as having been "banished" from the Garden of Eden for not complying with and obeying Adam. She is thought to be mentioned in Biblical Hebrew in the Book of Isaiah, and in Late Antiquity in Mandaean mythology and Jewish mythology sources from 500 CE onward. Lilith appears in historiolas (incantations incorporating a short Mythology, mythic story) in various concepts and localities that give partial descriptions of her. She is mentioned in the Babylonian Talmud ( 100b, 24b, 151b, 73a), in the ''Book of Adam and Eve'' as Adam's first wife, and in the Zohar Book of Leviticus, Leviticus 19a as "a hot fiery female who first cohabited with man".

Nadia Boulanger
Juliette Nadia Boulanger (; 16 September 188722 October 1979) was a French music teacher and conductor. She taught many of the leading composers and musicians of the 20th century, and also performed occasionally as a pianist and organist. From a musical family, she achieved early honours as a student at the Conservatoire de Paris but, believing that she had no particular talent as a composer, she gave up writing music and became a teacher. In that capacity, she influenced generations of young composers, especially those from the United States and other English-speaking countries. Among her students were many important composers, soloists, arrangers, and conductors, including Grażyna Bacewicz, Burt Bacharach, Daniel Barenboim, Lennox Berkeley, İdil Biret, Elliott Carter, Aaron Copland, John Eliot Gardiner, Philip Glass, Roy Harris, Quincy Jones, Dinu Lipatti, Igor Markevitch, Astor Piazzolla, Virgil Thomson, and George Walker. Boulanger taught in the U.S. and England, workin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie-Juliette Olga Lili Boulanger
Marie Juliette "Lili" Boulanger (; 21 August 189315 March 1918) was a French composer and the first female winner of the Prix de Rome composition prize. Her older sister was the noted composer and composition teacher Nadia Boulanger. Biography Early years As a Parisian-born child prodigy, Boulanger's talent was apparent at the age of two, when Gabriel Fauré, a friend of the family, discovered she had perfect pitch. Her parents, both of whom were musicians, encouraged their daughter's musical education. Her mother, Raissa Myshetskaya (Mischetzky), was a Russian princess who married her Paris Conservatoire teacher, Ernest Boulanger (1815–1900), who won the Prix de Rome in 1835. Her father was 77 years old when she was born and she became very attached to him. Her grandfather Frédéric Boulanger had been a noted cellist and her grandmother Juliette a singer. Boulanger accompanied her ten-year-old sister Nadia to classes at the Paris Conservatoire before she was five, sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

Observation Arc
In observational astronomy, the observation arc (or arc length) of a Solar System body is the time period between its earliest and latest observations, used for tracing the body's path. It is usually given in days or years. The term is mostly used in the discovery and tracking of asteroids and comets. Arc length has the greatest influence on the accuracy of an orbit. The number and spacing of intermediate observations has a lesser effect. Short arcs A very short arc leaves a high uncertainty parameter. The object might be in one of many different orbits, at many distances from Earth. In some cases, the initial arc was too short to determine if the object was in orbit around the Earth, or orbiting out in the asteroid belt. With a 1-day observation arc, was thought to be a trans-Neptunian dwarf planet, but is now known to be a 1 km main-belt asteroid. With an observation arc of 3 days, was thought to be a Mars-crossing asteroid that could be a threat to Earth, but was later ...

Simeiz Observatory
Simeiz Observatory (also spelled Simeis or Simeïs) was an astronomy research observatory until the mid-1950s. It is located on Mount Koshka, Crimea, , by the town of Simeiz. Part of the Crimean Astrophysical Observatory, it is currently used for laser based studies of the orbits of satellites. The Minor Planet Center (MPC) credits Simeiz Observatory as the location where a total of 150 minor planets were discovered by astronomers Grigory Neujmin, Sergey Belyavsky, Vladimir Albitsky, Grigory Shajn, Nikolaj Ivanov, Pelageya Shajn, Praskov'ja Parchomenko, Alexander Deutsch and Evgenij Skvorcov. As of 2017, the discovery of the minor planet is directly credited to Simeiz Observatory by the MPC. History The Simeiz Observatory was founded by Russian amateur astronomer Nikolai Maltsov, who later became a honored member of the Russian Academy of Sciences and after whom asteroid 749 Malzovia was named. In 1900, he built a tower for refractor at his land plot near Simei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecliptic
The ecliptic or ecliptic plane is the orbital plane of the Earth around the Sun. From the perspective of an observer on Earth, the Sun's movement around the celestial sphere over the course of a year traces out a path along the ecliptic against the background of stars. The ecliptic is an important reference plane and is the basis of the ecliptic coordinate system. Sun's apparent motion The ecliptic is the apparent path of the Sun throughout the course of a year. Because Earth takes one year to orbit the Sun, the apparent position of the Sun takes one year to make a complete circuit of the ecliptic. With slightly more than 365 days in one year, the Sun moves a little less than 1° eastward every day. This small difference in the Sun's position against the stars causes any particular spot on Earth's surface to catch up with (and stand directly north or south of) the Sun about four minutes later each day than it would if Earth did not orbit; a day on Earth is therefore 24 hours ...

Orbital Inclination
Orbital inclination measures the tilt of an object's orbit around a celestial body. It is expressed as the angle between a reference plane and the orbital plane or axis of direction of the orbiting object. For a satellite orbiting the Earth directly above the Equator, the plane of the satellite's orbit is the same as the Earth's equatorial plane, and the satellite's orbital inclination is 0°. The general case for a circular orbit is that it is tilted, spending half an orbit over the northern hemisphere and half over the southern. If the orbit swung between 20° north latitude and 20° south latitude, then its orbital inclination would be 20°. Orbits The inclination is one of the six orbital elements describing the shape and orientation of a celestial orbit. It is the angle between the orbital plane and the plane of reference, normally stated in degrees. For a satellite orbiting a planet, the plane of reference is usually the plane containing the planet's equator. For pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
