Discovered on 3 September 1994 by E. W. Elst at La Silla.
Orlande de Lassus (Roland Delattre, 1532-1594), a Franco-Flemish composer, is considered one of the most prolific and versatile composers of the late Renaissance. His 2000 works include motets, madrigals, chansons and lieder. Many of his masses are based on secular and even obscene themes.Naming citation (20080819/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
