What Are The Odds Your House Will Be Destroyed By An Asteroid?

If you haven't heard, a giant asteroid will buzz Earth on February 15. The asteroid, which has the catchy moniker 2012 DA14, is approximately 146 feet long and weighs 143,000 tons. What are the chances that an asteroid will hit your house? The bigger your house is the more likely it will be hit by an asteroid one day. I guess I'm pretty safe.
