  KEYWORDS: Siberian Fan Reliefs, SFR, Tunguska Catastrophe, Tunguska Cosmic Body, TCB

  ABSTRACT: Previous studies substantiated the fact that Tunguska Cosmic Body was in a near-Earth orbit prior to falling. This paper considers the events preceding the June 30 catastrophe. Identified are the Tunguska Cosmic Body orbital parameters and the factors resulting in the falling. The information from the Mount Wilson Observatory is provided, which confirms the fact that Tunguska Cosmic Body was in near-Earth orbit. The circumstances surrounding Tunguska Cosmic Body entry into near-Earth orbit are reviewed, and the event timing is identified. Substantiation is proposed of the relationship between Tunguska Cosmic Body and Comet Schwassmann-Wachmann. As to the Tunguska Cosmic Body breakup circumstances, the structure and the properties of its materials are proposed.
