(1960s survey to identify distant asteroids)

The Palomar-Leiden Survey (PLS) was a 1960s astronomical survey in search of distant minor planets carried out at Palomar Observatory in California and Leiden Observatory in the Netherlands. Three subsequent surveys in the 1970s (Palomar-Leiden Trojan surveys 1, 2, and 3: T-1, T-2, and T-3) specifically searched for Trojan asteroids. Over 4000 minor planets were discovered.
