145523 Lulin, provisional designation 2006 EM67, is an asteroid from the middle region of the asteroid belt, approximately 4 kilometers 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.[2]
The asteroid orbits the Sun at a distance of 2.2–3.2 AU once every 4 years and 7 months (1,665 days). Its orbit has an eccentricity of 0.18 and an inclination of 11° with respect to the ecliptic.[1] The earliest precovery was taken at ESO's La Silla Observatory in 1992, extending the asteroid's observation arc by 14 years prior to its discovery observation.[2]
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,[3] which is rather typical for a carbonaceous C-type body. As of 2016, the asteroid's rotation period and shape remain unknown.[1]
The minor planet was named after the Lulin mountain in central Taiwan, location of the discovering Lulin Observatory at an altitude of 2862 meters.[2] Naming citation was published on 2 April 2007 (M.P.C. 59389).[5]
