Named in honor of Richard M. Goldstein (1927– ), radar astronomer at the Jet Propulsion Laboratory, on the occasion of the twenty-fifth anniversary of his detection of the first radar echoes from a minor planet ( (1566) Icarus in June 1968). Goldstein also led observations that resulted in the first radar detections of Mars and of Saturn’s rings and in the discovery of the anomalous rotation of Venus. (M 22830) _ _.
