Every day the Earth is bombarded by debris from space, but the vast majority of objects entering the atmosphere are tiny, and burn up long before they reach the ground. However, larger bodies will penetrate deeper into the atmosphere, and can detonate with tremendous explosive force. The object that devastated 2000 square kilometres of Siberian forest in 1908 was only 60-meters in diameter, and exploded with a force of 12.5 megatons of TNT, a thousand times the power of the Hiroshima atomic bomb. The resulting damage template almost fits inside the M25 motorway around London.
If one ever hits you, then you’ll get your picture on the cover of the Tumbling Stone.
