Romulus, first king of Rome, reigned from 753 to 716 B.C. Legend has it that the twins Romulus and Remus were saved from the Tiber river by the wolf that raised them. In the first year of this reign Romulus founded the city. He was deified as Quirinus.Naming citation (20020427/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
