(31555) Wheeler Main-belt Asteroid
Discovered on 7 March 1999 by S. Sposetti at Gnosca.
John Archibald Wheeler (b. 1911), one of the world's finest theoretical physicists, was a professor at Princeton and later at the University of Texas. From nuclear physics and quantum theory, to relativity and gravitation, Wheeler's work has set the trajectory of research for more than half a century.Naming citation (WGSBN Bull. 4, #9, 5), IAU / Minor Planet Center, via NASA/JPL
