No asteroid risk in foreseeable future
Pasadena, Calif. (UPI) Feb 12, 2013
Despite the approach of an asteroid set to make a close flyby of Earth this week, an actual impact is unlikely for the foreseeable future, astronomers say. Although asteroid 2012 DA14 will fly past closer than some orbiting satellites, NASA says an analysis of its path shows no impact is possible. Meanwhile, U.S. astronomers have played down a report by the Voice of Russia quoting two Russian astronomers predicting a possible impact by another asteroid in 2106. The Russians sugges ... read more
