359E-390-One in 100,000

Friday the 13th appears to continue to be a lucky day for the human race. When astronomers first discovered Apophis in 2004 it appeared possible that this 3 million ton, 1,200 foot diameter asteroid traveling at 8 mi/s could impact our planet creating a crater a several miles diameter and more than a half mile deep. Additional observations over the years have eliminated this possibility as Apophis streaks by closer than the communications satellites on that lucky Friday the 13th. Further, current calculations have reduced the chances of Apophis colliding with Earth in the next 100 years to about one in 100,000. However, over the millennia Apophis is likely to strike the Earth as does one it's size once every 100,000 years or so.
