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.

| 42487 Ångström | Discovered 1991 Sept. 9 by F. Börngen and L. D. Schmadel at Tautenburg. |
| Swedish physicist Anders Jonas Ångström (1814-1874) is a cofounder of astrospectroscopy. He measured the wavelengths of about 1000 Fraunhofer lines, discovering among them some hydrogen lines. The `angstrom', a unit of length equal to the 10-10 meters, was named for him. |
