Andrew Fraknoi is chair of the astronomy department at Foothill College near San Francisco and senior educator at the Astronomical Society of the Pacific. He is a fellow of CSI, specializing in debunking pseudoscience connected with astronomy. Asteroid 4859 was named Asteroid Fraknoi by the International Astronomical Union to recognize his contributions to the public understanding of astronomy, but he is eager to reassure readers that his is an extremely boring main-belt asteroid that is in no danger of hitting Earth.
