Scientific paper

In 1983, Sekanina clearly demonstrated that the Tunguska object was asteroidal rather than cometary (Sekanina, 1983). He also demonstrated that Tunguska was an ordinary meteor, unusual only by its mass. The Tunguska object essentially self-destructed by its terminal burst and the remaining dust was highly altered. No unaltered meteorites have been recovered from Tunguska. Had the Tunguska object been smaller, some fragments would have survived to impact the Earth unaltered. One of the unanswered problems was the original petrological classification of the object and therefore its specific gravity.
