Our Earth, the planet we call home feels safe and cozy, but it hasn’t always been that way and chances are that someday another large asteroid will impact Earth.
Here is a list of Famous Craters around Earth – the results of previous collisions between Earth and Asteroids.
You can click on the “Calculate Impact Effects” links below and use Purdue’s Impact:Earth! to calculate the effects of these famous asteroid impacts.
Take a look at the Tunguska Fireball below. On June 30th, 1908 an asteroid 60 meters (196 ft.) in diameter is believed to have exploded in the atmosphere. The explosion flattened trees in the forests up to 700 miles away. Imagine if that asteroid had stayed aloft for a second or two longer before exploding. Cities like Paris or London would have been wiped off the map. (check the Wikipedia entry)
