Aftermath of the Tunguska Event In 1908 a stony asteroid with a mass of about 108 kilograms entered Earth’s atmosphere over the Tunguska region of Siberia. Its passage through the atmosphere made a blazing trail in the sky some 800 km long. The asteroid apparently exploded before reaching the surface, blowing down trees for hundreds of kilometers around “ground zero.”
