List Of Asteroid-discovering Observatories
The list of asteroid-discovering 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 It 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 international collaboration between Korea, China and Japan.

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 ...

Telescope
A telescope is a device used to observe distant objects by their emission, absorption, or reflection of electromagnetic radiation. Originally meaning only an optical instrument using lenses, curved mirrors, or a combination of both to observe distant objects, the word ''telescope'' now refers to 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 the 1930s and infrared telescopes in the 1960s. Etymology The word ''telescope'' was coin ...

Chichibu, Saitama
is a city located in Saitama Prefecture, Japan. , the city had an estimated population of 61,159 in 26,380 households and a population density of . The total area of the city is . Geography Chichibu is in the westernmost part of Saitama. Unlike other parts of the prefecture, it is largely mountainous and the population is concentrated in river terraces along the Arakawa River. It is Saitama's largest municipality in terms of surface area and shares borders with Tokyo, Yamanashi, Nagano and Gunma Prefectures. A large portion of the city belongs to Chichibu-Tama-Kai National Park. Because the region is not suitable for growing rice, many people have traditionally depended on sericulture farming. Limestone from Mount Bukō, which rises south of the city center, is another major source of income for the region. The city is shifting its focus toward sightseeing, taking advantages of its rich natural environment and relative closeness to the Tokyo metropolitan area. The city is al ...

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 The rotation period of a celestial object (e.g., star, gas giant, planet, moon, asteroid) may refer to its sidereal rotation period, i.e. the time that the object takes to complete a single revolution around its axis of rotation relative to the ... 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.

3361 Orpheus
3361 Orpheus (1982 HR) is an Apollo asteroid that was discovered on 24 April 1982 by Carlos Torres at Cerro El Roble Astronomical Station. Its eccentric orbit crosses that of Mars and Earth, and approaches Venus as well. From 1900 to 2100 it passes closer than 30 Gm to Venus 11, Earth 33, and Mars 14 times. It passed by Earth at a distance of about in 1937, 1978, 1982, and 2021 and will again in 2025. 3361 Orpheus is a potentially hazardous asteroid (PHA) because its minimum orbit intersection distance (MOID) is less than and its diameter is greater than 140 meters. The Earth-MOID is . With an observation arc of 36 years, the orbit is well-determined for the next several hundred years. The orbital solution includes non-gravitational forces. Missions 3361 Orpheus had been one of the originally proposed targets for the Near Earth Asteroid Rendezvous (NEAR) mission.

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.

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 OAN can be traced back to the Gillis Expedition, a project of the United States Naval Observatory. Led by James Melville Gilliss, it 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 equipment and the buildings that housed it to the government ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
