This coming week, an asteroid is going
to pass closer to Earth than TV satellites, but there is no immediate danger.
The asteroid is named DA14 and is traveling at 8 miles a second. But now many are recalling the Tunguska event, an asteroid or comet that exploded
over Siberia in June 1908. It wasn't until 1921 that an expedition explored the
area and realized the amount of devastation- 830 square miles of wilderness
flattened. The effect of the impact was seen all across Europe with a silver mist clouding the sky. Many feared an apocalypse at the time, but NASA has
explained that something, be it meteor, asteroid, or comet, hit the earth. The Tunguska
event has led to huge debate and wild speculation over the years. Thankfully,
the asteroid planned to pass close to earth soon poses no threats.
