20333 Johannhuth           Discovered 1998 Apr. 25 by the Lowell Observatory Near-Earth Object Search at the Anderson Mesa Station.
Johann Sigismund Huth (1763-1818) was a founder of astronomy at Kharkiv University, Russia (now Ukraine). He was a professor of this university during 1808-1811 and director of Tartu observatory (Estonia) from 1811 to 1818. Huth discovered four comets and estimated the diameter of (3) Juno by the eclipse method.
