983 Gunila (prov. designation: A922 OD or 1922 ME), is a dark background asteroid from the outer regions of the asteroid belt, approximately 74 kilometers (46 miles) in diameter. It was discovered on 30 July 1922, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in Germany.[1] The X-type asteroid has an ambiguous rotation period of 8.3 or 16.6 hours. It was named "Gunila", a common German female name unrelated to the discoverer's contemporaries, that was taken from the almanac Lahrer Hinkender Bote.[2]
