4045 Lowengrub, provisional designation 1953 RG, is a dark Alauda asteroid from the outer region of the asteroid belt, approximately 32 kilometers in diameter. It was discovered on 9 September 1953, by astronomers during the Indiana Asteroid Program at Goethe Link Observatory in Brooklyn, Indiana, United States.[10] The asteroid was named after American mathematician Morton Lowengrub, dean at Indiana University and one of the fathers of the WIYN Observatory.[2]
