NEAT May 2001 Interesting Objects

We discovered 10 Near-Earth asteroids: 6 Amors including 2 > 1km, and 4 Apollos including 1 PHA and 1 > 1km. We also discovered 3 comets including the eccentric, periodic Near-Earth Comet P/2001 J1 (NEAT), and a high-eccentricity Mars-crosser.

*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.
