Named in honor of Matthew J. Holman (1967– ), astronomer in the planetary sciences division at the Harvard-Smithsonian Center for Astrophysics. He is particularly known for his long-term investigations on the stability of the outer solar system by means of the sympletic integrator he codeveloped, and he has studied the stability of planets around other stars. Recently, he has also become an active observer of centaurs and transneptunian objects. (M 34619) _ _.
