Bohyunsan Optical Astronomy Observatory
The list of asteroid-discovering Observatory, observatories contains a section for each observatory which has discovered one or more asteroids, along with a list of those asteroids. For each numbered asteroid, the Minor Planet Center lists one or more discoverers who have been given credit for the discovery. Sometimes these are individuals (by modern rules there can be no more than three co-discoverers), and sometimes the credit is given to an organization (for instance, Purple Mountain Observatory). Observatories Andrushivka Astronomical Observatory The Andrushivka Astronomical Observatory is a private observatory near Andrushivka in Zhytomyr oblast, Ukraine. The observatory has IAU observatory code A50. It has discovered the following asteroids: Bohyunsan Optical Astronomy Observatory The Korean Bohyunsan Optical Astronomy Observatory (BOAO), located at Mount Bohyeon near the city of Yeongcheon, is a member of the East-Asian Planet Search Network, an internationa ...

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 ...

Telescope
A telescope is a device used to observe distant objects by their emission, Absorption (electromagnetic radiation), absorption, or Reflection (physics), reflection of electromagnetic radiation. Originally, it was an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects – an optical telescope. Nowadays, the word "telescope" is defined as a wide range of instruments capable of detecting different regions of the electromagnetic spectrum, and in some cases other types of detectors. The first known practical telescopes were refracting telescopes with glass lenses and were invented in the Netherlands at the beginning of the 17th century. They were used for both terrestrial applications and astronomy. The reflecting telescope, which uses mirrors to collect and focus light, was invented within a few decades of the first refracting telescope. In the 20th century, many new types of telescopes were invented, including radio telescopes in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

3691 Bede
3691 Bede , provisional designation , is an Amor asteroid discovered on March 29, 1982, by Luis E. González at Cerro El Roble. Based on lightcurve studies, Bede has a rotation period In astronomy, the rotation period or spin period of a celestial object (e.g., star, planet, moon, asteroid) has two definitions. The first one corresponds to the '' sidereal rotation period'' (or ''sidereal day''), i.e., the time that the objec ... of 226.8 hours, but this figure is based on less than full coverage, so that the period may be wrong by 30 percent or so.

2741 Valdivia
2741 Valdivia ( ''prov. designation'': ) is a background asteroid from the central regions of the asteroid belt, approximately in diameter. It was discovered on 1 December 1975, by Chilean astronomers Carlos Torres and Sergio Barros at the Cerro El Roble Station northwest of Santiago de Chile. The asteroid was named after Spanish conquistador Pedro de Valdivia. Orbit and classification ''Valdivia'' is a non-family asteroid from the main belt's background population.

Cerro El Roble Station
The National Astronomical Observatory of Chile (Spanish: ''Observatorio Astronómico Nacional de Chile'' - OAN) is an astronomical observatory owned and operated by the Department of Astronomy of the University of Chile (UCh). It is located on Cerro Calán, a hill in the commune of Las Condes. The commune is an eastern suburb of Santiago located in Santiago Province of the Santiago Metropolitan Region. OAN was founded in 1852 and became a part of UCh in 1927. The facility on Cerro Calán was completed in 1962. History The National Astronomical Observatory of Chile (OAN) can be traced back to the Gillis Expedition, a project of the United States Naval Observatory, led by James Melville Gilliss, who arrived in Chile in 1849 to observe Mars and Venus from the southern hemisphere so as to improve solar parallax. Gilliss and his party set up their equipment on Santa Lucia Hill, a small rise in downtown Santiago. After completing the project in 1852, Gilliss sold the equipm ...
