1046 Edwin, provisional designation 1924 UA, is a background asteroid from the outer regions of the asteroid belt, approximately 30 kilometers (20 miles) kilometers in diameter. It was discovered on 1 December 1924, by Belgian–American astronomer George Van Biesbroeck at the Yerkes Observatory in Wisconsin, United States, who named it after his son, Edwin Van Biesbroeck.[1] The potentially metallic asteroid has a short rotation period of 5.29 hours.[4]
