10290 Kettering           Discovered 1985 Sept. 17 at the Oak Ridge Observatory.
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.
