On February 4, 2011, the asteroid 2011 CQ1 narrowly missed the earth, coming within 3,400 miles (5471 km). Five days later, a larger asteroid called 2011 GA7 passed within 65,000 miles—both astronomical near misses. On February 15, 2011, a silver streak appeared in the sky over Pennsylvania and was seen in New York, New Jersey, Connecticut and Maryland. Some astronomers are concerned that an astoroid named Apophis will strike the earth in 2036. Will this be earth's doom?
