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.

207385 Maxou           Discovered 2005 Sept. 4 by P. Kocher at Observatoire Naef, Marly.
Despite refusal of credit for a new building at Freiburg University, Max "Maxou" Aebischer (1914-2009) succeeded in getting it built with the help of private funds---a risky undertaking in his position as director of the education department. Aebischer also reorganized primary and middle schools in Freiburg.
