1985 PJ. Discovered 1985 Aug. 14 by E. Bowell at Anderson Mesa.

Named in honor of Martha S. Hanner, planetary scientist at the Jet Propulsion Laboratory who specializes in groundbased and space studies of particulate matter in the solar system, especially cometary dust. Her publications attest to her work as an enthusiastic observer of comets at infrared wavelengths, as an organizer of the P/Halley infrared monitoring program at the Infrared Telescope Facility on Mauna Kea, as a champion of improvements in infrared photometric standards, and on the nature of zodiacal light. She has investigated the formation of infrared spectral features in dust and the scattering properties of dust. Hanner is an energetic supporter of better science education for young people, to which end she has been a teacher and organizer of space science seminars for science teachers. (M 18461)
