Tracking a Space Rock’s Streak Past Earth

41:43 minutes

Asteroid 2012 DA14 is half the size of a football field, and whizzing towards the Earth at over 17,000 miles per hour. Don’t worry, it won’t hit us. But on Friday, February 15th it makes its closest approach, scraping by the Earth’s surface closer than many satellites. Join Ira Flatow and Flora Lichtman for special live coverage of this near encounter, with first-hand reports from astronomers around the world.
