Wide Angle: Asteroid Apophis

Rogue asteroids and comets populate the solar system far and wide, but the most impending threat to our fragile planet is a building-sized space rock called Apophis.

The chances that this 23,000-ton near-Earth object will whack us in the year 2029 (or 2036, if it missed the first time) are incredibly slim -- but a less forgiving asteroid could be just around the cosmic bend.

In this Discovery Space Wide Angle, we explore the technologies that could divert asteroids, peek at the nastiest space rocks out there and ponder how humanity might blow a deflection (even with the best tools at its disposal).
