Russian Fireball Won't Be Last Surprise Asteroid AttackSubmitted by Bob-45 on Mon, 02/18/2013 - 04:17
The world will have to live with surprise asteroid attacks on the scale of Friday's Russian fireball, at least for a while.
The meteor that exploded over the Russian city of Chelyabinsk without warning Friday (Feb. 15), damaging hundreds of buildings and wounding more than 1,000 people, was caused by a space rock about 50 feet (15 meters) wide, researchers said.
Asteroids of this size are both difficult to detect and incredibly numerous, so it will take a long time for astronomers to find and map out the orbits of all the potentially dangerous ones. Besides, researchers have bigger fish to fry. [NONSENSE! What if a few hundred of the babies decide to "make a visit" in close proximity?]
