2085 Henan
2085 Henan, provisional designation , is a potentially slow rotating asteroid and the parent body of the Henan family in the central regions of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 20 December 1965, by astronomers at the Purple Mountain Observatory in Nanking, China. The asteroid was named for the Henan Province in China. Orbit and classification ''Henan'' is the parent body of the Henan family (), a large asteroid family, family of L-type asteroids in the intermediate main-belt, which can be further divided into four distinct families. It orbits the Sun in the Kirkwood gap, central asteroid belt at a distance of 2.5–2.9 Astronomical unit, AU once every 4 years and 5 months (1,619 days; semi-major axis of 2.70 AU). Its orbit has an orbital eccentricity, eccentricity of 0.09 and an orbital inclination, inclination of 4Degree (angle), ° with respect to the ecliptic. A first observation of this asteroid was found on a pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Purple Mountain Observatory
The Purple Mountain Observatory (), also known as Zijinshan Astronomical Observatory is an astronomical observatory located on the Purple Mountain in the east of Nanjing. Description The Purple Mountain Observatory was established in 1934 funded by the Nationalist Government of the Republic of China and administered by Academia Sinica. The longtime director of the observatory from 1950 to 1984 was Chinese astronomer Zhang Yuzhe (, 1902–1986, also known as Y. C. Chang). By the late 1980s, increasing light pollution in Nanjing meant Purple Mountain was no longer viable as a working observatory. It has since shifted its focus to public education, with much of the actual scientific work being carried out in its five branch observatories located at Qinghai (in Delingha), Ganyu, Xuyi, Honghe (in Jiamusi), and Qingdao. The Minor Planet Center credits the observatory, simply referred to as Nanking, with the discovery of 149 minor planets between 1955 and 1983, while the observator ...
