"According to NASA scientists, the trajectory of the Russia meteor was significantly different than the trajectory of the asteroid 2012 DA14, making it a completely unrelated object. Information is still being collected about the Russia meteor and analysis is preliminary at this point. In videos of the meteor, it is seen to pass from left to right in front of the rising sun, which means it was traveling from north to south. Asteroid DA14's trajectory is in the opposite direction, from south to north." Can you imagine if they had collided? What would be the odds of that?
"Hey! What was that?"
Just over 100 years ago, a meteor exploded over Tunguska, Siberia, causing an explosion the size of a nuclear bomb. And, there is a theory that the legend of Noah's Ark was created from a tsunami caused by a meteor that struck the Indian Ocean.
We're sitting ducks here on our little blue planet. The good news is that if anything of substantial size comes our way, we will be forewarned. If we can do anything to detract it remains to be seen. We'll just call Bruce Willis.
