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.

| 7896 Švejk | Discovered 1995 Mar. 1 by Z. Moravec at Klet. |
| Named for a literary character created by Jaroslav Hašek, Czech writer and humorist (1883-1923). His "good soldier" Josef Švejk is devoted to the disintegrating Austrian-Hungarian monarchy regime, but by his simplicity (or perhaps his ingenuity) he helps to reveal its flaws. |
