Discovered on March 2, 1981 by Schelte Bus at the Siding Spring Observatory, it was given the provisional designation "mp|1981 EO|21". It was later renamed "Catcheller", a portmanteau of Joseph Heller and Catch-22, the novel he authored, on the suggestion of Brian Marsden. [MPC 38199 "Minor Planet Center"]
