NEAT September 2003 Interesting Objects

In September we discovered 9 NEAs: 7 Amors, including 1 > 1km, and 2 Apollos. We also discovered 2 periodic comets and 1 Mars-crossing asteroid.

*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 ~0.2 km (0.1 mile) and approach close enough to present a potential hazard but not a current hazard.
