see § List of discovered minor planets

The Palomar Planet-Crossing Asteroid Survey (PCAS) was an astronomical survey, initiated by American astronomers Eleanor Helin and Eugene Shoemaker at the U.S Palomar Observatory, California, in 1973.[2][3][4][5] The program is responsible for the discovery of 95 near-Earth Objects including 17 comets,[6] while the Minor Planet Center directly credits PCAS with the discovery of 20 numbered minor planets during 1993–1994.[1] PCAS ran for nearly 25 years until June 1995. It had an international extension, INAS, and was the immediate predecessor of the outstandingly successful NEAT program.[6]
