1040 Klumpkea, provisional designation 1925 BD, is a Tirela asteroid from the outer regions of the asteroid belt, approximately 23 kilometers (14 miles) in diameter. It was discovered on 20 January 1925, by Russian–French astronomer Benjamin Jekhowsky at the Algiers Observatory in North Africa.[1] This highly elongated asteroid is the largest member of the stony Tirela family – also known as the Klumpkea family – and has a longer than average rotation period of 59.2 hours.[11] It was named after American astronomer Dorothea Klumpke.[2]
