17879 Robutel           Discovered 1999 Jan. 22 by the OCA-DLR Asteroid Survey at Caussols.
Philippe Robutel (b. 1964) works at the Institut de Mécanique Céleste in Paris on the stability of the three-body problem, especially on the existence of quasiperiodic motions for the application of KAM theory.
