9122 Hunten           Discovered 1998 Mar. 22 by Spacewatch at Kitt Peak.
Donald M. Hunten (b. 1925), of the Lunar and Planetary Laboratory, has studied the atmospheres of the planets and their satellites, participating in space missions from Pioneer to Cassini. He used mid-infrared spectroscopy to study the comet impacts on Jupiter and has studied Martian water vapor and lightning on Venus.
