Spaceweather.com- 4/26/13
Potentially Hazardous Asteroids (PHAs [2]) are space rocks larger than approximately 100m that can come closer to Earth than 0.05 AU. None of the known PHAs is on a collision course with our planet, although astronomers are finding new ones [3] all the time.

On April 26, 2013 there were 1397 potentially hazardous asteroids.
