(10521) Jeremyhansen Main-belt Asteroid
Discovered on 14 September 1990 by H. Debehogne at La Silla.
Jeremy Roger Hansen (b. 1976) became a Canadian astronaut in 2009. Hansen earned his pilot's license at age 17 and studied at the Royal Military College in Kingston, Ontario. He did research on wide-field-of-view satellite tracking. Astronaut training has taken him to the high Arctic to study geology, and to the ocean floor, living in the Aquarius habitat.Naming citation (WGSBN Bull. 2, #15, 9), IAU / Minor Planet Center, via NASA/JPL
