On June 30, 1908, in Tunguska, Siberia, was recorded one of the most powerful explosions in history, which devastated in an instant a whole forest area fortunately uninhabited.
60 million trees were cut down, the power of the explosion was estimated to be 1,000 times that of the bomb that destroyed Hiroshima.
An exceptional luminosity in the middle of the night is noted during several days in Europe, so much so that one could read the newspaper at night in the Caucasus.
In 2013, the discovery of three meteorite fragments lifted part of the mystery, and moved towards the hypothesis of a meteorite.
The event would be well due to a meteorite, however this one would not have struck the ground, nor exploded in flight, but would have bounced on the atmosphere. This body would have flown over the earth, then would have left in direction of the Sun. This hypothesis has the advantage of explaining the absence of impact crater and debris
