Did Monday see especially tense to you?
While we were blissfully playing in the snow we came within a cosmic gnats breath of being squished by a giant rock. Mashed flat, totally unaware. SPLAT !!
Monday morning an asteroid about the size of 10-story building came speeding past the earth. According to NASA's Jet Propulsion Laboratory the Asteroid named only "2009 DD45" came within 48,000 miles of hitting earth. That may sound like a huge distance until you remember that's less than one-fifth of the distance to the moon.
You think that sounds like an unlikely science fiction story. Well it's happened before. In June 1908 an asteroid roughly the same size ( about 150 feet in diameter ) exploded over Tunguska, Siberia. That blast was estimated to have been about 1,000 times more powerful than the atomic bomb over Hiroshima. It destroyed over 800 square miles of forest and kicked a massive dust cloud into the air.
But don't worry it missed. However scientist predict it will pass even closer next time it flies by. They also insist their was no real danger. Hmmmm !
