145523 Lulin, provisional designation Template:Mp, is a background asteroid from the central region of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 7 March 2006, by Taiwanese astronomers Hung-Chin Lin (林宏欽) and Ye Quanzhi (葉泉志) at Lulin Observatory in central Taiwan.[1] It was named for the Lulin mountain and the observatory site.[1]
Orbit and classification
Lulin is a non-family asteroid from the main belt's background population.[2][3] It orbits the Sun in the central asteroid belt at a distance of 2.2–3.2 AU once every 4 years and 7 months (1,664 days; semi-major axis of 2.75 AU). Its orbit has an eccentricity of 0.18 and an inclination of 11° with respect to the ecliptic.[4] The earliest precovery was taken at ESO's La Silla Observatory in March 1992, extending the asteroid's observation arc by 14 years prior to its discovery observation.[1]
Naming
This minor planet was named after the Lulin mountain in central Taiwan, location of the discovering Lulin Observatory at an altitude of 2862 meters.[1] The official Template:MoMP was published by the Minor Planet Center on 2 April 2007 (M.P.C. 59389Script error: No such module "Check for unknown parameters".).[5] At the observatory, Comet Lulin was discovered in 2007.
Physical characteristics
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 3.9 kilometers in diameter and its surface has a low albedo of 0.073,[6] which is rather typical for a carbonaceous C-type body. As of 2018, no rotational lightcurve of Lulin has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[4][7]
