80801 Yiwu           Discovered 2000 Feb. 8 by the Spacewatch Near-Earth Asteroid Survey at Kitt Peak.
Yiwu, with a population of 20~000, is a small county within the Xinjiang Uyghur Autonomous Region in Northwest China. It was the prime location chosen by many shadow chasers from all over the world to witness the total solar eclipse on 2008 Aug. 1. These included W. K. Y. Young, who suggested the name for this object.
