Asteroid hurtles towards earth. Scientists were today, January 4th, 2014, warning of a possible asteroid collision with the Earth.
The answer is yes, because scientists are increasingly tracking the space rocks and debris that enter Earth's atmosphere. The largest meteor since the 2013 impact in Chelyabinsk, Russia, hit Earth on Feb. 6, and NASA's meticulous Fireballs and Bolides Report has ensured the news went public eventually. How did such a large object collide with Earth without attracting notice? The truth is that it happens much more frequently than many people might think.
