Asteroid to whiz past Earth Friday
Boston (AFP) Feb 15, 2013
NASA is closely tracking an asteroid large enough to destroy a city that is set to whiz past Earth on Friday in what the US space agency says is the closest flyby ever predicted for such a large object. The 150-feet (45-meter) wide asteroid - dubbed 2012 DA 14 - is expected to pass about 17,200 miles (27,000 kilometers) above the Earth at the time of closest approach, about 2:25 pm EST (1925 GMT), NASA said. "This distance is well away from Earth and the swarm of low Earth-orbiting satellites, ... read more
