1197 Rhodesia, provisional designation 1931 LD, is a dark background asteroid from the outer regions of the asteroid belt, approximately 48 kilometers (30 miles) in diameter. It was discovered on 9 June 1931, by South African astronomer Cyril Jackson at the Union Observatory in Johannesburg.^[1] The likely C-type asteroid has a rotation period of 16.1 hours.^[10] It was named for Rhodesia, a former British colony and unrecognised state, which is now Zimbabwe.^[13]
