COMET METEORITIC AND COMET NATURE

E.V. Dmitriev

Astronomical Society

Due to well hypothesis it is believed that meteorites are fragments of asteroids. But no detected on the Earth meteorite was associated with parent comet. Nevertheless, authors investigations of tektites and so-called pseudo-meteorites have shown that fragments of comets fall down to the Earth regularly. Proves to cometarys meteorites finding as well as their origin, composition and classification are done. It is concluded that cometarys meteorites including tektites have widely differentiated composition and by set of their properties are in good concordance with eruption origin of comets. A model of comet nuclei of erupted comet is present. Some the peculiarities of its deceleration in the Earths atmosphere, including eruption of comet dust out of the atmosphere and genesis of piroclastic meteorite jet as addition dangerous factor, are described and illustrated by the final stages of the of the Tunguska and Vitim bolides.
