1986 JN1. Discovered 1986 May 5 by C. S. Shoemaker and E. M. Shoemaker at Palomar.

Named for Gerald J. Wasserburg, professor of geology and geophysics at the California Institute of Technology. One of the pioneers in the development of techniques of isotopic age determination, Wasserburg is famous for the very high precision ages obtained in his laboratory for lunar rocks. These ages have provided much of the primary chronological control for deciphering the history of evolution of the moon. He has also carried out extensive investigations of the ages of meteorites and developed key evidence bearing on the earliest history of the solar system and of nucleosynthesis events that predate the solar system.
