Asteroid 1997 XF 11, which it had been thought might
pass very close to the Earth, will probably not come
closer than 600,000 miles, according to calculations by
scientists at NASA's Jet Propulsion Laboratory. The
new calculations put the risk of collision with Earth at
zero, said scientists Don Yeomans and Paul Chodas. 

The new estimate was made after scientists looked again at images made
in 1990 at the Palomar Observatory, before the asteroid was discovered.
The images will be posted to the Near-Earth Asteroid Tracking Web
site. NASA's Ames Research Center provides a general discussion of
the issues on its "Asteroid and Comet Impact Hazards" Web site. Click
