Discovered on 8 February 1994 by E. W. Elst at La Silla.
Nathan Rosen (1909–1995) was an American and Israeli physicist noted for his study on the structure of the hydrogen molecule. He is also remembered for two papers published in 1935: one on entangled wave functions and the Einstein–Podolsky–Rosen paradox; and another about the Einstein–Rosen bridge, the first known kind of wormhole.Naming citation (WGSBN Bull. 5, #9, 18), IAU / Minor Planet Center, via NASA/JPL
