172996 Stooke is a small asteroid that orbits in the main belt of the asteroid belt. It was discovered in 2006 by Paul A. Wiegert at the Mauna Kea Observatory.[1] The asteroid is named after the Canadian astronomer and cartographer Philip John Stooke, who studies the history of planetary exploration and mapping and has developed cartographic tools for mapping non-spherical worlds. His reference work, the International Atlas of Lunar Exploration, was published in 2007.
