Ernesto Cesaro (1859-1906) was a prolific mathematician and professor at the universities of Palermo and Naples. He made contributions to the intrinsic geometry of curves but is best remembered for his study of the summability of divergent series.Naming citation (20010309/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
