Named in honor of astronomer Jeffrey A. Larsen (1967– ), whose software expertise has allowed the Spacewatch project to upgrade its computational capability in the automatic detection of small solar system bodies. While making observations for Spacewatch he discovered comets P/1997 V1 and C/1998 M3 and more than seven near-earth objects. Prior to joining the Spacewatch group, he participated in the Automated Plate Scanner project at the University of Minnesota, where he studied a large asymmetry in the distribution of faint halo/thick disk stars in the Milky Way.
