    3430 Bradfield (1980 TF4) is a main-belt asteroid discovered on October 9, 1980 by Carolyn S. Shoemaker at Palomar.

    Named in honor of William A. Bradfield, rocket engineer of Dernancourt, South Australia. Discoverer of eighteen comets, Bradfield was chiefly responsible for the greatly increased rate of discovery of bright comets from the southern hemisphere during the 1970s and 1980s.

    With an absolute magnitude of 12.4, asteroid Bradfield is assumed to be 9–20 km in diameter.[1]
