(9512) Feijunlong is an asteroid located in the main middle belt . It was discovered on February 13, 1966 at the Observatory on Purple Mountain ( IAU code 330) in Nanjing .
The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong. The timeless (non- osculating ) orbital elements of (9512) Feijunlong are almost identical to those of four smaller asteroids, assuming the absolute magnitudes of 16.4, 16.4, 16.2 and 16.6 versus 12.6 : (222652) 2001 XP 182 , (293458) 2007 ET 195 , (305165) 2007 VP 248 and (382304) 2013 OQ 5 .
The mean diameter of the asteroid was calculated to be 7.036 km (± 0.283). The albedo of 0.357 (± 0.101) indicates a light surface.
(9512) Feijunlong was named on December 15, 2005 after the Chinese Taikonaut Fei Junlong , who made China's first multi-day space flight from October 12 to 17, 2005 together with Nie Haisheng . An asteroid was named after Nie Haisheng on December 15, 2005: (9517) Niehaisheng .
