508 Princetonia is a largeasteroid, a type ofminor planet, orbiting in theasteroid belt. It was discovered byRaymond Smith Dugan atHeidelberg, Germany in 1903 and named "Princetonia" forPrinceton University inNew Jersey in theUnited States.[4]
Dugan found it during his time atKönigstuhl Observatory withMax Wolf in Heidelberg, Germany.[2] At the time he was working on his PhD fromHeidelberg University. The asteroid is located in the outer areas of the main asteroid belt and is about 140 km (87 mi) in diameter according to data fromIRAS, an infrared space observatory in the 1980s.[5]
