Substantiation of the Western Trajectory of the Tunguska Cosmic Body

Abstract

Although more than 100 years have passed since the Tunguska event, no hypothesis has yet been proposed that would be consistent with the entire set of available facts and observations. A hypothesis has been put forward that the Tunguska Cosmic Body was an ice comet and its fall was accompanied by the fall of smaller fragments, whereas the TCB and fragments fell from intermediate Earth orbits. This explains all the observed phenomena without exception, including those that occurred long before the catastrophe. In this paper, we present eyewitnesses’ reports and objective materials obtained in the event area and confirming the TCB passage in the direction from West to East. The western trajectory has been traced for 3500 km from the Volga to the Lower Tunguska. We have carried out a detailed analysis of the eyewitnesses’ reports revealing the circumstances of passage of a huge fireball. We provide criticism of trajectories constructed without taking new information into account. We have estimated the energy released during this event and determined the mechanical properties of the comet matter. Science may obtain with new objects to study the direct impact of the comet matter on the Earth’s surface. This may be useful for evaluating the comet-related hazard.
