NEAT March 2004 Interesting Objects

In March we discovered 3 NEAs: 2 Amors with 1>1km in diameter, and an Apollo > 1 km in diameter. We recovered a large Amor, 1994 LY, that had been "lost" for 10 years. We also discovered 2 periodic comets and a high-inclination 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.
