1551 Argelander, provisional designation 1938 DC1, is a main belt asteroid discovered on February 24, 1938, by Yrjö Väisälä at the Iso-Heikkilä Observatory in Turku, Finland.[1]

It is named after Friedrich Wilhelm Argelander (1799–1875), author of the famous Bonner Durchmusterung and 19th-century head of the ancient observatory at Turku. The lunar crater Argelander is also named after him.[2]
