2013 Meteor Event

On February 15, 2013, 2012 DA14 passed approximately 27,700 km (17,200 mi) above the surface of Earth. This was closer than satellites in geosynchronous orbit. The asteroid was not visible to the unaided eye. (Wikipedia page ).

On the same day there was a meteor strike in Russia (Wikipedia page ).

What would have happened if the two paths had been reversed - so the small body flies past, and DA14 hits the Earth?
