1490 Limpopo, provisional designation 1936 LB, is a carbonaceous–metallic asteroid from the inner regions of the asteroid belt, approximately 18 kilometers in diameter. It was discovered on 14 June 1936, by English-born South African astronomer Cyril Jackson at Johannesburg Observatory in South Africa.^[13] It was named for the Limpopo River.^[2]
