(11353) Guillaume Main-belt Asteroid
Discovered on 5 December 1997 by ODAS at Caussols.
Guillaume Scholl (b. 1987) tested early versions of an automatic code for detecting minor planets developed by his father, astronomer Hans Scholl of the Observatoire de la Côte d´Azur. As a result, recent versions of the code are more user friendly.Naming citation (20000523/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
