Unusual reliefs on the
Earth’s surface were found in aerial photographs of Eastern Siberia in the late
20th century. The facts justifying the connection are given by Siberian
Fan Reliefs and the Tunguska Cosmic Body. It is most natural to assume that we
are dealing with the falling of numerous fragments of a collapsed comet. The
more likely version is that the comet is captured by the Earth-Moon system and
remains in Earth orbit for some time.
