| Summary: | Title screen A catastrophic collision of cosmic body with the Earth occurred above the Tunguska region of Siberia on June 30, 1908. Studies propose cometary1 and asteroid2,3 origin of the Tunguska projectile; some researchers4 believe it was an iron meteorite though no sizable fragments of iron meteorite have been recovered. John Anfinogenov proposed a hypothesis that the Tunguska projectile belonged to a new-type planetary-origin meteorite after he found a fresh hypervelocity impact structure produced by exotic sedimentary boulder (John's rock) in the epicentral area; some splinters of John's rock had fusion crust-like surface5,6; and some structural features resampled shatter cones. Nature of the Tunguska projectile remains controversial. Here we propose a hypothesis that the Tunguska cosmic body was a ruble pile asteroid. |
