1980 TD4. Discovered 1980 Oct. 9 by C. S. Shoemaker at Palomar.

Named in honor of Sherman S. C. Wu, chief photogrammetrist of the Astrogeology Branch of the U.S. Geological Survey. Wu and his group have published highly detailed topographic maps of selected regions of the Moon and of Mars, including Olympus Mons and parts of the Valles Marineris. These maps, obtained by means of analytical photogrammetry, represent the most accurate solutions extant of the morphology of surfaces on extraterrestrial bodies. (M 8153)
