If A Giant Asteroid Is Headed For Earth, Who Will Protect Us? How About Bill Nye?

Odds are a giant asteroid won't end up hitting the Earth anytime soon: NASA officials told a U.S. congressional panel in March that there's only a one in 20,000 chance of a truly dangerous asteroid - one big enough to destroy a continent or worse - hitting this planet over the course of the next year.

But as scientist and broadcaster Bill Nye says in the video above, "just because it's unlikely, doesn't mean it's not a big deal."

Nye teamed up with the Canadians behind ASAPScience, Mitchell Moffit and Gregory Brown, to create this video, in which he breaks down some of the possible ways humanity could stop, or at least slow down, a large asteroid on a collision course with Earth.

Some of his answers are kind of what you'd expect - like sending a giant spacecraft to push or pull the asteroid and slow it down.

If that reminds you of the movie 'Armageddon', by the way, it's understandable. But according to some Master's students at the University of Leicester, the "plant a nuclear weapon inside the asteroid" plan portrayed in that movie wouldn't have worked so well in real life.

Some of Nye's other ideas are more surprising, like something called 'Laser Bees'. You'll have to watch the video to find out more about that.

If you're wondering what kind of damage a direct hit from a large asteroid could do, DVice has an interesting - and scary - run-down of the potential fall-out from various types and sizes of asteroids striking the Earth.
