Small asteroids that hit the Earth between 1994-2013

  • Chelyabinsk-sized impacts (500 kilotons TNT) every few decades
  • Tunguska-sized impacts (5 megatons TNT) every few centuries

An event such as depicted below would affect the entire globe not just a city. NASA is building a defense system to alter the path of dangerous asteroids ensuring they miss the earth.
