Millennium Asteroid Greets New Year
NASA’s Near Earth Asteroid Tracking System (NEAT), operated by JPL, discovered the first asteroid of the new millennium on Jan. 1. This is 200 years after the discovery of Ceres, the first and largest asteroid ever discovered. NEAT scientists compare snapshots of the same parts of the sky to find moving objects, which may be small or faint.
