NotesThis small asteroid follows an eccentric orbit through the inner Solar System that carries it across the orbits of all the inner planets including Earth, though at an inclined angle to the plane of the Solar System. Debris from this Apollo asteroid is the source of the Geminid meteor shower that occurs in mid-December each year.
