The trajectory, structure and origin of the Chelyabinsk asteroidal impactor
Original language description
We report an analysis of selected video records of the Chelyabinsk superbolide of 15 February 2013, with energy equivalent to 500kilotons of trinitrotoluene, and details of its atmospheric passage. We found that its orbit was similar to the orbit of thetwo-kilometre-diameter asteroid 86039 (1999NC43), to a degree of statistical significance sufficient to suggest that the two were once part of the same object. The bulk strength--the ability to resist breakage--of the Chelyabinsk asteroid, of about onemegapascal, was similar to that of smaller meteoroids and corresponds to a heavily fractured single stone. The asteroid broke into small pieces between the altitudes of 45 and 30kilometres, preventing more-serious damage on the ground. The total mass of surviving fragments larger than 100grams was lower than expected.
