Asteroid 21359, Geng, was discovered on April 6, 1997 by MIT Lincoln Laboratory's Near-Earth Asteroid Research program at Socorro, New Mexico. It has a period of 5 years, 14 days.
It was named for Rockville, Maryland high-school student Sherri Yifan Geng (born 1987), who entered a health-science project in the 2005 Intel Science Talent Search, attaining the finals.
The meaning of asteroid Geng seems to be what its name might suggest: gangs, to be ganged up on.
The glyph for Geng is mine.
