7864 Borucki           Discovered 1982 Mar. 14 by A. Mrkos at Klet.
William Borucki (b. 1939) founded and developed the Kepler mission that led to the discovery of numerous exoplanetary systems and to significant contributions to stellar astrophysics and astroseismology of evolving stars. He also determined plasma properties of hypervelocity shock waves that were used in the heat shield of the Apollo missions.
