(10506) Rydberg Main-belt Asteroid
Discovered on 13 February 1988 by E. W. Elst at La Silla.
Johannes Robert Rydberg (1854-1919) was a Swedish physicist educated at the University of Lund who held the chair of physics from 1901 to 1919. He is well-known for the Rydberg constant, which appears in a spectroscopic expression that relates the various lines in the spectra of chemical elements.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
