SPACE JUNKIE

摘要

Paul Chodas studies near-Earth objects, and part of his job is to investigate the reports of possible mini-moons. Based at NASA's Jet Propulsion Laboratory in Pasadena, California, Chodas's latest case is asteroid 2010 KQ, discovered in May 2010 by the Catalina Sky Survey in Tucson, Arizona. Just a few metres across, it seemed a dead ringer for a mini-moon.
