NEAT April 2002 Interesting Objects

Thus far in April we discovered 11 NEAs with NEAT: 5 Amors and 6 Apollos including 2 PHAs and 1> 1km. In addition we discovered a "scattered disk object" and a Centaur.

*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.
