62 Erato (/ˈɛrətoʊ/ ERR-ə-toh) is a large and dark, probably carbonaceous Themistian asteroid. It is a member of the Eos family.[1]
Erato is the first asteroid to have been credited with co-discoverers, Oskar Lesser and Wilhelm Forster, who discovered it on September 14, 1860 from the Berlin Observatory. It was their first and only asteroid discovery. The name was chosen by Johann Franz Encke, director of the observatory, and refers to Erato, the Muse of lyric poetry in Greek mythology.[3]
