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.

| 129595 Vand | Discovered 1997 Nov. 2 by J. Ticha and M. Tichy at Klet. |
| Vladimír Vand (1911-1968) started his career with the study of variable stars and spectroscopy in Prague. Later he invented a calculating machine for x-ray analysis of crystal structures, contributed to the theory of viscosity of solutions and cooperated with Francis Crick on the structure of double helix DNA molecules. |
