12999 Toruń, provisional designation 1981 QJ2, is a carbonaceous Baptistina
Edward Bowell at Lowell Observatory's Anderson Mesa Station in Flagstaff, Arizona, and named after the Polish city of Toruń.[2]
Orbit and classification
Toruń is a carbonaceous C-type asteroid and a member of the small Baptistina family. It orbits the Sun in the inner main-belt at a distance of 1.8–2.7 AU once every 3 years and 5 months (1,252 days). Its orbit has an eccentricity of 0.19 and an inclination of 6° with respect to the ecliptic.[1] The first precovery was taken at Goethe Link Observatory in 1957, extending the asteroid's observation arc by 24 years prior to its discovery.[2]
