1245 Calvinia (prov. designation: 1932 KF) is a stony Koronian asteroid from the outer regions of the asteroid belt, approximately 30 kilometers (19 miles) in diameter. It was discovered on 26 May 1932, by South African astronomer Cyril Jackson at the Union Observatory in Johannesburg.[1] The S-type asteroid is likely elongated and has a rotation period of 4.9 hours.[6] It was named for the city of Calvinia in South Africa.[2]
