    77185 Cherryh, provisional designation 2001 FE9, is a dark background asteroid from the intermediate asteroid belt, approximately 4 kilometers in diameter.[4]

    It was discovered on 20 March 2001 at the George Observatory in Needville, Texas, by amateur astronomers Don J. Wells and Alex Cruz of the Fort Bend Astronomy Club (FBAC) Asteroid Discovery Team. The discovery was confirmed the next night by Keith Rivich of the FBAC.

    The asteroid is a non-family from the main belt's background population. It was named by the discoverers after C. J. Cherryh (b. 1942), the award-winning American science fiction and fantasy author.[2]
