课程简介
Asteroid collisions with the Earth are the worst possible natural disasters that the Earth can face. And the bad news is that this kind of collisions has happened in the past, and will happen again in the future. Probably the most famous such collision is the one from sixty five million years ago which caused mass extinctions, including the dinosaurs. A recent example is the meteor strike in the Russian Chelyabinsk region on February 15, 2014.
