You guys appear to be a pretty erudite group, you've probably heard of this. But for those of you who haven't, allow me to introduce "Apophis".

Very interesting topic.

re: Apophis

According to NASA the "Impact Probability (cumulative)" is 2.2e-05
http://neo.jpl.nasa.gov/risk/a99942.html

which means:

0.002200000% chance of Earth impact,
or, 1 in 45,000 chance
or, 99.99780000% chance the asteroid will miss the Earth
