5395 Shosasaki           Discovered 1988 Sept. 14 by S. J. Bus at Cerro Tololo.
Sho Sasaki (b. 1960), a professor at the University of Tokyo, has carried out laser irradiation experiments to simulate the processes of lunar-like space weathering. He is also a lead researcher in interplanetary dust particle experiments that are part of many Japanese planetary missions.
