(13117) Pondicherry is an asteroid of the main belt , which on 9 October 1993 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 asteroid 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.
(13117) Pondicherry was named on April 7, 2005 after the southern Indian city of Puducherry (Pondicherry during the colonial period) on the coast of the Bay of Bengal , which was the capital of French India until 1954 .
