1062 Ljuba, provisional designation 1925 TD, is a carbonaceous background asteroid from the outer regions of the asteroid belt, approximately 58 kilometers (36 miles) in diameter. The asteroid was discovered on 11 October 1925, by Soviet–Russian astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[1] It was named after female paratrooper Ljuba Berlin, who died at an early age.[2] The C-type asteroid has a longer-than average rotation period of 33.8 hours.[4]
