How dangerous are near-Earth asteroids? 5 key questions answered.
On Feb. 15, asteroid 2012 DA14, discovered a year ago, cleared Earth by a scant 17,200 miles. The same day, a smaller, unrelated asteroid that no one saw coming exploded 12 to 15 miles above Russia’s Chelyabinsk region. Events that day highlight the risk that near-Earth objects (NEOs) can pose – although to some extent, humans can counter them.

Russian asteroid highlights astronomers' challenge: predicting such space objects
Astronomers have cataloged about 95 percent of the space objects wider than half a mile – those that could destroy civilization. But they have found less than 1 percent of the objects 100 feet across or larger, a class that includes the asteroid that flitted past Earth on Friday.

Huge asteroid won't strike Earth on Friday. But what about the next time?
There's no chance that the 150-foot-wide asteroid 2012 DA14 will strike our planet, but it's only a matter of time before a large space rock does, say scientists.

Friday's near-miss asteroid could help track more dangerous ones
Asteroid 2012 DA14 will buzz within 17,200 miles of Earth – a record for a known object of that size. While it's no threat to hit, it might help scientists find and track others that are.
