Rocks From Space!
 
On any clear night you might see a handful of “shooting stars” streaking across 
the night sky. Long ago people thought the stars were actually falling from the 
sky. Now we know these brief streaks in the night sky, called meteors, are tiny 
bits of solar system debris most of it smaller than a pea. Entering the Earth’s 
thin upper atmosphere at tens of thousands of miles an hour, heat from friction 
completely vaporizes the intruders. Much of this debris comes from the tail of 
comets.

On the morning of February 12, 1947 startled witnesses reported seeing a 
fireball brighter than the sun streaking across the Russian skies. Traveling at 
over 31,000 miles an hour the meteor plummeted down to 15,000 feet where it 
violently exploded from the stress of the heating and atmospheric shock. Over 
more than a half a square mile area debris impacted the ground leaving 80 foot 
diameter craters 20 feet deep. This was something much bigger than comet dust, 
It is estimated that the meteor weighed over 200,000 pounds before it exploded. 
How often does this happen? Russia was visited by another space rock just this 
past February 15th. An event captured by many video cameras.
