976 Benjamina (prov. designation: A922 FD or 1922 LU) is a dark background asteroid from the outer regions of the asteroid belt, approximately 81 kilometers (50 miles) in diameter. It was discovered on 27 March 1922, by Russian-French astronomer Benjamin Jekhowsky at the Algiers Observatory in North Africa.[1] The large X/D-type asteroid has a rotation period of 9.7 hours and is likely regular in shape. It was named after the discoverer's son.[2]
