(2531) Cambridge is an asteroid of the main belt , which on 11 June 1980 by the US American astronomer Edward LG Bowell at the Anderson Mesa Station (IAU code 688) of the Lowell Observatory in Coconino County was discovered.

The asteroid was named after the two university cities of Cambridge in England and Cambridge in Massachusetts , which, along with the University of Cambridge and Harvard University and the Massachusetts Institute of Technology, are home to world-renowned universities.

(2531) Cambridge belongs to the Eos family, a group of asteroids, which typically have large semi-axes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
