NEAT December 2002 Interesting Objects

In December we discovered 6 NEAs with NEAT: 4 Amors including 1>1km, 1 Apollo, and 1 Aten that is a PHA. We also discovered the periodic Comet P/2002 X2 (NEAT).

*Amors, Apollos, and Atens are the three categories of Near-Earth asteroids (NEAs). Amor asteroids approach the Earth's orbit from the outside, Apollo asteroids cross the Earth's orbit, and Aten asteroids approach the Earth's orbit from the inside. Potentially Hazardous asteroids (PHAs) are larger than ~200 m (0.1 mile) and approach close enough to present a potential hazard but not a current hazard.
