(10069) Fontenelle is an asteroid of the main belt , which on 4 February 1989 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory ( IAU code 809) of the European Southern Observatory in Chile was discovered.
The celestial body belongs to the Eos family , a group of asteroids, which typically have large semiaxes from 2.95 to 3.1 AU , bounded inward by the Kirkwood gap of the 7: 3 resonance with Jupiter , and orbital inclinations between 8 ° and 12 °. The group is named after the asteroid (221) Eos . The family is believed to have emerged from a collision more than a billion years ago.
The asteroid was named on July 28, 1999 after the French writer and representative of the Early Enlightenment Bernard le Bovier de Fontenelle (1657–1757), who is usually referred to in literary history by his family name Fontenelle . In 1686, in his work Entretiens sur la pluralité des mondes , he discussed the possible existence of extraterrestrial forms of life and, as expected, was put on the index by the Catholic Church , which in no way detracted from the success of the work.
