24102 Jacquescassini           Discovered 1999 Nov. 9 by C. W. Juels at Fountain Hills.
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.
