Possible asteroid collision scheduled for April 13th, 2036.

A group of astronauts and engineers warns that an asteroid may pass uncomfortably close to Earth that day. The chances it will actually hit are just one in 45,000, but even at those odds, the scientists warn, the United Nations should consider a response. ... Nobody knows for sure what it would take to push a massive asteroid off its course, but the theoretical possibilities include detonating weapons on an asteroid's surface or using a gravitational pull to alter a possible collision course.

But it could also break an asteroid into many pieces, all still headed toward Earth.

Everybody knows the best way to survive an asteroid collision is to ride your bike to the top of the nearest hill. Duh.
