Discovered on 23 August 1998 by P. G. Comba at Prescott.
Édouard Jean-Baptiste Goursat (1858–1936) made contributions to many areas of mathematical analysis. He was associated with several French universities and was regarded as an outstanding teacher. His monumental Cours d'analyse mathématique (1900–1910) was used by generations of students.Naming citation (WGSBN Bull. 4, #9, 5), IAU / Minor Planet Center, via NASA/JPL
