Named in honor of Nobuhisa Kojima (1933– ), who has been interested in astronomy since childhood. Kojima was the first Japanese amateur to make a Schmidt camera, and he discovered two comets (1970r and 1972j) photographically with a 0.30-m reflector of his own making. Kojima was also the first Japanese amateur to discover a minor planet that was given a provisional designation (1973 MA). Kojima is an inspiration for other astronomical discoverers. (M 20159) _ _.
