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.

| 4030 Archenhold | Discovered 1984 Mar. 2 by H. Debehogne at the European Southern Observatory. |
| Named in memory of the German astronomer Friedrich Simon Archenhold (1861-1939). In 1896 he made it possible to build the world's longest refractor (focal length 21 meters), which is still in use at the Archenhold Observatory in Berlin---Europe's first public observatory. As its first director Archenhold had the aim of introducing astronomy to everyone. Name suggested by A. Gnädig and A. Doppler and endorsed by L. D. Schmadel. |
