(4965) Takeda Main-belt Asteroid
Discovered on 6 March 1981 by S. J. Bus at Siding Spring.
Hiroshi Takeda (b. 1934), professor at the Chiba Institute of Technology in Narashino, has conducted seminal research on both lunar meteorites and primitive achondrites. These studies have contributed to our understanding of the melting and differentiation of small bodies in the solar system.Naming citation (20001013/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
