1939 Loretta, provisional designation 1974 UC, is a carbonaceous Themistian asteroid from the outer region of the asteroid belt, approximately 30 kilometers in diameter. It was discovered on 17 October 1974, by American astronomer Charles Kowal at Palomar Observatory in California, who named it after his daughter, Loretta Kowal.[2][9] The discovery of the asteroid took place during Kowal's follow-up observations of Jupiter's moon Leda, which he had discovered one month prior.[10]
