172996 Stooke           Discovered 2006 May 25 by P. A. Wiegert at Mauna Kea.
Philip John Stooke (b. 1952), a geographer at the University of Western Ontario, studies the history of planetary exploration and mapping. He has developed cartographic tools for mapping non-spherical worlds. His reference work, International Atlas of Lunar Exploration, was published in 2007.
