(10069) Fontenelle Main-belt Asteroid

Discovered on 4 February 1989 by E. W. Elst at La Silla.

Named in memory of Bernard Le Bovier, sieur de Fontenelle (1657-1757), well-known for his famous work Entretiens sur la pluralité des mondes (1686). Many of the ideas of the Enlightenment appear in embryonic form in his works. In De l´origine des fables (1724), he compared pagan religion with established religion.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
