(13087) Chastellux Main-belt Asteroid
Discovered on 30 July 1992 by E. W. Elst at La Silla.
François-Jean de Chastellux (1734-1788), author of De la félicité publique (1757), was a founder of the social sciences. He sought to determine whether society is susceptible to amelioration, if not to perfection. He cited America as an example of man's ability to progress through liberty, reason and equality.Naming citation (20050125/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
