1032 Pafuri
1032 Pafuri, provisional designation 1924 SA, is a dark background asteroid from the outer regions of the asteroid belt, approximately 65 kilometers (40 miles) in diameter. It was discovered on 30 May 1924, by English astronomer Harry Edwin Wood at the Union Observatory in Johannesburg, South Africa. The asteroid was named for the river in the Pafuri Triangle in South Africa, created by the confluence of the Limpopo and Levubu rivers. The body's spectral type and rotation period are still poorly determined.
