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.

89664 Pignata           Discovered 2001 Dec. 19 by the Asiago-DLR Asteroid Survey at Cima Ekar.
Giuliano Pignata (b. 1972), a member of the Asiago-DLR Asteroid Survey, contributes in a decisive way to the calibration and adaptation of the CCD detector to the telescope. His main research interest is now supernovae, but he still searches for minor planets in supernova survey images.
