NEAT April 2003 Interesting Objects

In April we discovered 6 NEAs with NEAT: 4 Apollos, including 1 > 1km and 3 PHAs, and 2 Amors. We also discovered the high-inclination Comet C/2003 H3 (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 ~0.2 km (0.1 mile) and approach close enough to present a potential hazard but not a current hazard.
