Abstract : The Spacewatch program discovers small bodies (asteroids and comets) in the solar system and analyzes their distributions with orbital parameters and absolute magnitude. Scanning of the night sky is conducted with a charged-coupled device (CCD) imaging detector. About 1200 to 2000 square degrees of sky are searched each year to a V magnitude limit of 21.5 Spacewatch discoveries support studies of the Centaur, Trojan, Main-Belt. and Earth-approaching asteroid populations. These studies provide information about the evolution of these objects and their orbits.
