This video is just to remind us how fragile our world is. And also, how lucky we are to even exist, literally! On October 2014, Comet 2013 A1 has 1 in 2000 chances to hit Mars. Scientists believe that this will be most likely a near miss rather than a collision. But think how would you feel if you knew that in one year a massive comet might hit Earth with the speed of 200.000 Km per hour releasing about a third of the energy being released by the asteroid that sent the dinosaurs extinct? The comet has a diameter of 1 to 3 kilometers and it will release energy equivalent to 35 Million Megatons of TNT.
One thing is for sure: All NASA's probes will be watching out there!
