Jacques Cassini (1677-1756), a.k.a. Cassini II, succeeded his father, G. D. Cassini (Cassini I) as director of the Paris Observatory in 1712. He improved the geographic knowledge of France, studied the proper motion of stars and compiled the first tables of the orbital motions of Saturn's satellites.Naming citation (20020921/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
