2531 Cambridge, provisional designation 1980 LD, is a stony Eoan
Edward Bowell at Lowell's Anderson Mesa Station in Arizona, United States. The asteroid was named for the "centers of learning in England and in Massachusetts".[2]
Classification and orbit
Cambridge is a member of the
606),[3][4] the largest asteroid family in the outer main belt consisting of nearly 10,000 known asteroids.[11]: 23 It orbits the Sun at a distance of 2.8–3.2 AU once every 5 years and 3 months (1,906 days). Its orbit has an eccentricity of 0.06 and an inclination of 11° with respect to the ecliptic.[1]
It was first identified as A916 FE Simeiz Observatory in 1916. The body's observation arc begins with a precovery taken at Lowell Observatory in 1931, or 49 years prior to its official discovery observation at Anderson Mesa.[2]
