Planet-Crossing Asteroid Survey

from Wikipedia, the free encyclopedia

The Palomar Planet Crossing Asteroid Survey (PCAS) was started in 1973 by Eleanor F. Helin and Eugene M. Shoemaker . The result of the program is the discovery of several thousand asteroids of all types including a multitude of orbiting asteroids and 20 comets . PCAS ran for nearly 25 years and ended in June 1995. It is the immediate precursor of the JPL and NASA -operated project Near-Earth Asteroid Tracking (NEAT).
