Caballito, Buenos Aires
Caballito (; Spanish for "little horse") is a ''barrio'' (neighborhood) of the Argentine capital, Buenos Aires. It is the only ''barrio'' in the administrative division ''Comuna'' 6. It is located in the geographical centre of the city, limited by the following streets and avenues: Rio de Janeiro, Av. Rivadavia, Av. La Plata, Av. Directorio, Curapaligüe, Av. Donato Álvarez, Av. Juan B. Justo, Av. San Martín, and Av. Ángel Gallardo. The name is said to come from the horse-shaped (Spanish ''caballo'') weather vane from a local ''pulpería'' (gauchos' bar); ''Caballito'' meaning "Little horse". Places of interest In Caballito there are numerous points of interest; the "English District" with British style "Fin de Siècle" architecture, the Ferro Carril Oeste football Club (or "Verdolaga"), the "Historical Tramway museum of Buenos Aires", the old "Mercado del Progreso" (Market of Progress) a neighborhood favorite since 1890, the Italian Club and the Portuguese Club.

Astrograph
An astrograph (or astrographic camera) is a telescope designed for the sole purpose of astrophotography. Astrographs are mostly used in wide-field astronomical surveys of the sky and for detection of objects such as asteroids, meteors, and comets. Improvements in photography in the middle 19th century led to designs dedicated to astrophotography, and they were also popular in the 20th century. As in other photography, chemicals were used that respond to light, recorded on a glass photographic plate or sometimes on photographic film. Many observatories of this period used an astrograph, beside instruments like the transit telescope, great refractors, and chronometers, or instruments for observing the Sun. Astrographs were often used to make surveys of the night sky, and one of the famous projects was Carte du Ciel. Discoveries using an astrograph include then-planet Pluto. Rather than looking through the telescope, it was discovered by using a blink comparator with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Astronomical Observatories
This is a partial list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minor Planet Circulars
The Minor Planet Center (MPC) is the official body for observing and reporting on minor planets under the auspices of the International Astronomical Union (IAU). Founded in 1947, it operates at the Smithsonian Astrophysical Observatory. Function The Minor Planet Center is the official worldwide organization in charge of collecting observational data for minor planets (such as asteroids), calculating their orbits and publishing this information via the '' Minor Planet Circulars''. Under the auspices of the International Astronomical Union (IAU), it operates at the Smithsonian Astrophysical Observatory, which is part of the Center for Astrophysics along with the Harvard College Observatory. The MPC runs a number of free online services for observers to assist them in observing minor planets and comets. The complete catalogue of minor planet orbits (sometimes referred to as the "Minor Planet Catalogue") may also be freely downloaded. In addition to astrometric data, the MPC coll ...

International Astronomical Union
The International Astronomical Union (IAU; , UAI) is an international non-governmental organization (INGO) with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded on 28 July 1919 in Brussels, Belgium and is based in Paris, France. The IAU is composed of individual members, who include both professional astronomers and junior scientists, and national members, such as professional associations, national societies, or academic institutions. Individual members are organised into divisions, committees, and working groups centered on particular subdisciplines, subjects, or initiatives. the Union had 85 national members and 12,734 individual members, spanning 90 countries and territories. Among the key activities of the IAU is serving as a forum for scientific conferences. It sponsors nine annual symposia and holds a triannual General Assembly that sets policy ...

4756 Asaramas
4756 Asaramas, provisional designation , is a stony rare-type Eoan asteroid from the outer region of the asteroid belt, approximately 11 kilometers in diameter. It was discovered on 21 April 1950, by astronomers at the La Plata Astronomical Observatory in Argentina. It is named for the astronomical society Asociación Argentina Amigos de la Astronomía. Classification and orbit ''Asaramas'' is a member of the Eos family (), the largest asteroid family in the outer main belt consisting of nearly 10,000 asteroids. It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,915 days). Its orbit has an eccentricity of 0.06 and an inclination of 9 ° with respect to the ecliptic. As no precoveries were taken and no prior identifications were made, the body's observation arc begins with its official discovery observation at La Plata.

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 ...

La Plata Astronomical Observatory
The La Plata Astronomical Observatory () is an observatory located in the city of La Plata, capital of the province of Buenos Aires, Argentina. Its IAU code is 839. History La Plata was a planned city, intended as the capital of the province after the city of Buenos Aires became the Argentina's Federal Capital. The observatory was the result of the 1872 establishment of the National Meteorological Bureau, enacted by President Domingo Sarmiento on an initiative by U.S. astronomer Benjamin Apthorp Gould (who lived in Argentina between 1870 and 1885). The construction of the Observatory was funded by a decree passed by La Plata's founder, Buenos Aires Province Governor Dardo Rocha, on 7 May 1881. In this decree the Engineering Department was ordered to set up plans and a budget for several public buildings, including an astronomical observatory. Designed by the master planner of La Plata, Pedro Benoit, ground was broken on the observatory in November 1883. A year earlier, the Pari ...

Transit Of Venus
A transit of Venus takes place when Venus passes directly between the Sun and the Earth (or any other superior planet), becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus is visible as a small black circle moving across the face of the Sun. Transits of Venus reoccur periodically. A pair of transits takes place eight years apart in December (Gregorian calendar) followed by a gap of 121.5 years, before another pair occurs eight years apart in June, followed by another gap, of 105.5 years. The dates advance by about two days per 243-year cycle. The periodicity is a reflection of the fact that the orbital periods of Earth and Venus are close to 8:13 and 243:395 commensurabilities. The last pairs of transits occurred on 8 June 2004 and 5–6 June 2012. The next pair of transits will occur on 10–11 December 2117 and 8 December 2125. Transits of Venus were in the past used to determine the size of the Solar System. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
