(21496) Lijianyang Main-belt Asteroid
Discovered on 1 May 1998 by LONEOS at Anderson Mesa.
Jianyang Li (b. 1976), University of Maryland, has studied the surface light-scattering properties of minor planets and comets. He has discovered a correlation of photometric properties with outgassing on comet 19P/Borrelly; and, on (1) Ceres, spatially varying strong ultraviolet absorption by an unidentified species.Naming citation (20080718/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
