(9298) Geake Main-belt Asteroid
Discovered on 15 May 1985 by E. Bowell at Anderson Mesa.
At the University of Manchester's Institute of Science and Technology, John E. Geake (1925-1998) was well known for his laboratory interpretation of the optical polarization of the lunar and asteroidal surfaces. He invented the first direct-reading linear refractometer, one of which he designed for the Cassini-Huygens Titan probe.Naming citation (20000726/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
