Ah yes... a 96.9% chance it misses us. 

Truly terrible odds.

I mean, if we can see it coming 8 years in advance, that thing must be bigger than Texas!

Depending on the impact angle, size, and composition (e.g. the below might have been a comet) it might not hit the surface, it could explode in the atmosphere:

The Tunguska explosion was a massive air burst that occurred on June 30, 1908, over Siberia, flattening about 2,000 square kilometers of forest. It is believed to have been caused by the explosion of a small asteroid or comet in the atmosphere, with an energy equivalent to 10-15 megatons of TNT.

Some where south of 200m diameter.

Crater diameter of approximately 1 mile diameter. Most likely impact line is in the southern hemisphere, south America to Africa and across to india

Just saw news that the impact probability has now been revised to essentially zero (for better or worse cheeky):

Keep in mind that those odds were similar to taking a 32-spoke bike wheel (common on commuter and road bikes) and turning it into a roulette wheel with one segment between spokes representing Earth getting smashed by an asteroid.

In reply to GameboyRMH :

That's almost like 31 out of 1000 chance it hits you know.

It's all fun and games until the probability wave collapses resulting in a realized outcome.
