For accurate long-term ephemerides, please instead use our Horizons system.This orbit viewer was implemented using two-body methods, and hence should not be used for determining accurate long-term trajectories (over several years or decades) or planetary encounter circumstances.

| 10069 Fontenelle | Discovered 1989 Feb. 4 by E. W. Elst at the European Southern Observatory. |
| 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. |
