The total surface area of planet Earth is over 500,000,000 sq km, so the chances of a direct hit on any one person, even with a 1 sq km asteroid, are over five hundred million to one against.
Of course a strike by a 1 sq km meteor would be an extinction level event.
Updated Dec. 28, 2007 -- Astronomers have identified asteroid 2007 WD 5 in archival imagery. With these new observations, scientists at NASA's Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif have refined their trajectory estimates for the asteroid. Based on this latest analysis, the odds for the asteroid impacting Mars on Jan. 30 are now 1-in-25 -- or about 4 percent.
