Scientists recently revealed that a large asteroid now has a 1 in 75 chance of impacting the Martian surface in the next few weeks. While the exact course of the asteroid is extremely difficult to predict, and will likely not make contact with the planet, it is an interesting scientific development for scientists globally. If the impact occurs, it is expected to make a crater approximately 1 kilometer across. It would also send a huge dust cloud into the atmosphere. The asteroid, only measuring approximately 50 meters across, passed within 8 million miles of the Earth and is currently between the Earth and Mars. Scientists believe the strike on the Martian surface would be comparable to the huge asteroid impact in Siberia in 1908, which resulted in the death of 80 million trees. This would be the first time scientists ever got to witness a direct impact of a asteroid on a planets surface.
