9922 Catcheller is a main belt asteroid. It orbits the Sun once every 3.72 years.[1] It is associated with the Nysa family of asteroids.[3]
Discovered on March 2, 1981 by Schelte Bus at the Siding Spring Observatory, it was given the provisional designation "1981 EO21". It was later renamed "Catcheller", a portmanteau of Joseph Heller and Catch-22, the novel he authored, on the suggestion of Brian Marsden.[4]
