PASADENA, Calif. – Two asteroids, several meters in diameter and in unrelated orbits, will pass within the moon's distance of Earth on Wednesday, Sept. 8.

Both asteroids should be observable near closest approach to Earth with moderate-sized amateur telescopes. Neither of these objects has a chance of hitting Earth. A 10-meter-sized near-Earth asteroid from the undiscovered population of about 50 million would be expected to pass almost daily within a lunar distance, and one might strike Earth's atmosphere about every 10 years on average.
