(8069) Benweiss Main-belt Asteroid
Discovered on 2 March 1981 by S. J. Bus at Siding Spring.
Benjamin P. Weiss (b. 1973) is a professor of planetary Science at MIT. He leads a laboratory for measuring magnetic properties of meteorites, where detection of remnant paleomagnetic fields has implications for the early heating, melting, and differentiation histories of minor-planet parent bodies.Naming citation (20120506/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
