Hank gives us the skinny on three plans NASA scientists have come up with to save Earth from an asteroid impact. Hopefully we'll never have to use any of them.

Visit http://science.nasa.gov/ for breaking science news. On Feb. 15th an asteroid about half the size of a football field will fly past Earth closer than many man-made satellites. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet.

Buckle up for a trip to the asteroid belt -- though it's not nearly as dangerous out there as you might think. But there's a LOT waiting to be discovered, including some crucial clues about the formation of the solar system itself. ---------- Like SciShow?
