Abstract

Shown, that estimations of the Chelyabinsk body size order of 20–30 m (15/02/2013 phenomenon), publishing in the press, are overstated significantly. Estimations of its explosion height are wrong. On the basis of the destructions by action of the shock wave, the height of explosion must be no more than 10–12 km. We think, that the Chelyabinsk meteorite had diameter ∼5.6 m and mass ∼300 tons if its density was 3 g/cm3.

Keywords: bolide; physical properties of bolides; shock wave; destructions
