(29208) Halorentz Main-belt Asteroid
Discovered on 9 September 1991 by Borngen, F., Schmadel, L. D. at Tautenburg.
The Dutch physicist Hendrick Antoon Lorentz (1853-1928) formulated the classic electron theory and predicted the Zeeman effect. He derived the Lorentz transformation, the Lorentz contraction, time dilation and the velocity dependence of the mass. He shared the 1902 Nobel Prize for physics with his student Zeeman.Naming citation (20020624/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
