Chelyabinsk_meteorite

The Chelyabinsk meteorite (Russian: Челябинский метеорит, Chelyabinskii meteorit) is the fragmented remains of the large Chelyabinsk meteor of 15 February 2013 which reached the ground after the meteor's passage through the atmosphere. The descent of the meteor, visible as a brilliant superbolide in the morning sky, caused a series of shock waves that shattered windows, damaged approximately 7,200 buildings and left 1,491 people injured. The resulting fragments were scattered over a wide area.
The largest fragment raised from the bottom of Lake Chebarkul on 16 October 2013 had a mass of 540 kg (1,190 lb) and the total mass of other 7 meteorite fragments found nearby was 84.4 kg (186 lb).
