1974 UB. Discovered 1974 Oct. 17 by E. F. Helin at Palomar.
Named in honor of James G. Williams, celestial mechanician who extended the theory of secular perturbations to orbits of high inclination. This minor planet lies very near one of the secular resonances discovered by Williams, and its argument of perihelion librates around the value of 90 degrees. (M 5688)
