Dugan found it during his time at Königstuhl Observatory with Max Wolf in Heidelberg, Germany.[2] At the time he was working on his PhD from Heidelberg 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 from IRAS, an infrared space observatory in the 1980s.[5]
