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 im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Astronomical Observatories
This is a 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 of atmo ... [...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 collect ...

International Astronomical Union
The International Astronomical Union (IAU; french: link=yes, Union astronomique internationale, UAI) is a nongovernmental organisation with the objective of advancing astronomy in all aspects, including promoting astronomical research, outreach, education, and development through global cooperation. It was founded in 1919 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. As of 2018, the Union had over 13,700 individual members, spanning 90 countries, and 82 national members. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Physical characteristics ''Asaramas'' has been characterized as a L-type asteroid by PanSTARRS photometric sur ... [...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 ...

La Plata Astronomical Observatory
The La Plata Astronomical Observatory ( es, Observatorio Astronómico de La Plata) 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 observa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Of Venus
frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than three times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ciudad De Buenos Aires
Buenos Aires ( or ; ), officially the Autonomous City of Buenos Aires ( es, link=no, Ciudad Autónoma de Buenos Aires), is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos Aires" can be translated as "fair winds" or "good airs", but the former was the meaning intended by the founders in the 16th century, by the use of the original name "Real de Nuestra Señora Santa María del Buen Ayre", named after the Madonna of Bonaria in Sardinia, Italy. Buenos Aires is classified as an alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking. The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include t ...
