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.

9611 Anouck           Discovered 1992 Sept. 2 by E. W. Elst at the European Southern Observatory.
Anouck Vrouwe (b. 1978) studied physics at Nijmegen, specializing later in scientific journalism. At Davros (Switzerland), she has been involved with the study of wind velocities in order to derive models for the prediction of avalanches.
