(12301) Eotvos Main-belt Asteroid
Discovered on 4 September 1991 by E. W. Elst at La Silla.
Loránd Eötvös (1848-1919) was a Hungarian physicist who played a leading part in Hungarian science for almost half a century. He is well known from his torsion-balance experiments, improving the limits on any deviation from the proportionality of inertial and gravitational masses.Naming citation (20040928/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
