The Center for Computational Astrophysics (CCA) is a research organization in Oak Park, Illinois, whose staff performs research into current areas of astronomy and applications of probability, statistics, and Monte Carlo simulations into other areas of inquiry. The center is the home of the Near Earth Asteroid Reconnaissance Project, a network of amateur astronomers and small observatories involved in the discovery and determination of the orbits of near-earth asteroids, or more generally near-earth objects, with possible earth-crossing orbits. History CCA was founded in 1997 by its current director, astronomer Dr. Les Golden, a former instructor at the University of Illinois at Chicago.
