Will Mars be rocked by a massive comet in 2014? Maybe a little. Maybe a lot
. A comet
will definitely pass close to the Red Planet on October 19, 2014
From the first link: . . . It’s entirely possible, even likely, Mars will pass right through this cloud of material. And the closer the comet gets, the more likely it is Mars will get pelted by the debris set loose from the nucleus itself. . . . If the nucleus does hit the planet, well. . . . Doing a rough calculation, I get an explosive yield of roughly one billion megatons: That’s a million billion tons of TNT exploding. Or, if you prefer, an explosion about 25 million times larger than the largest nuclear weapon ever tested on Earth. . . The crater left behind would be hundreds of kilometers across, and be the largest impact Mars has seen in a long, long time. Mind you, once again, there is no guarantee this comet will hit Mars.
