Discovered on 16 October 1999 by Kusnirak, P., Pravec, P. at Ondrejov.
Sean E. Urban (b. 1962) has made significant advances to astrometry, including completion of the reductions of the 22,000 Astrographic Catalogue plates. These data formed the basis of proper motions for the most important reference star catalogs of the late 20th and early 21st centuries, including Tycho-2 and the UCAC.Naming citation (MPC batch dated 2018-05-29), IAU / Minor Planet Center, via NASA/JPL
