Re: Asteroid Near Miss Past Earth Today
n September, NASA announced that it has spotted about 90 percent of the largest asteroids (the size of a mountain or bigger) that can come near Earth. About 911 such giant space rocks have been confirmed. Astronomers estimate there are about 981 big near-Earth objects that occasionally creep close to our planet. Asteroid 2012 BX34 was the second space rock to fly relatively close by Earth this week, Asteroid Watch scientists said. On Jan. 23, another small asteroid — called 2012 BS1 — passed by the planet at a range of about 745,000 miles (1.2 million km), which is about 3.1 times the Earth-moon distance. "Asteroid 2012 BS1 is so small (about 7 meters) it would disintegrate in our atmosphere if it were to come close to Earth," the Asteroid Watch team wrote. Astronomers with NASA and other science teams routinely scan the skies in search of near-Earth asteroids that could pose a danger to the planet. Experts estimate that asteroids about 460 feet (140 m) across and bigger can cause widespread devastation near their impact sites, though a larger space rock would be required to cause destruction on a global scale. |

Re: Asteroid Near Miss Past Earth Today
Anything bigger than 1km will wipe you out as well no matter where it hits.
