| The standard version of the "Tunguska event" goes like this: A small asteroid or comet fragment entered Earth's atmosphere June 30, 1908, over Siberia. It exploded from the heat of reentry before reaching the ground, flattening some 770 square miles (2,000 square kilometers) of forest near the Tunguska River. |
