(10290) Kettering Main-belt Asteroid
Discovered on 17 September 1985 by Oak Ridge Observatory at Harvard.
The Kettering Group of amateur space sleuths, founded in the 1960s by G. E. Perry, monitored and analyzed radio transmissions from Soviet satellites, often scooping official news media. Perry's young students were eventually supplemented by a world-wide array of amateurs who continue the Group's work.Naming citation (20000320/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
