NASA, FEMA Hold Asteroid Emergency Planning Exercise : What would we do if we discovered a large asteroid on course to impact Earth? That highly unlikely scenario was discussed at a recent NASA-FEMA tabletop exercise.

In NASA's words "It will come interestingly close," but its all good. NASA also points out that the Wal-Mart size chunk of interstellar rock shouldn't be cataclysmic .. unless it enters earths atmosphere and you are with fifty miles or so from where it hits, then you might have problem. The narrator also points out that a similar sized space rock may have obliterated  Tunguska, Siberia back in 1908 but otherwise , no worries. As if we didn't have enough to worry about ..
