[60][61] [14][121][122] The Sodankylä Geophysical Observatory,[33] Russian sources,[123] the European Space Agency,[124] NASA[14] and the Royal Astronomical Society[125] all concluded that the two asteroids had widely different trajectories and therefore could not have been related.

[26] The Chelyabinsk meteor is thought to be the biggest natural space object to enter Earth's atmosphere since the 1908 Tunguska event,[27][28][29] and the only one confirmed to have resulted in many injuries,[30][Note 1] although a small number of panic-related injuries occurred during the Great Madrid Meteor Event of 10 February 1896. Damage stretched for 500 square kilometers, destroying 7,200 building and injuring over 1,400 people in … [64], The blast created by the meteor's air burst produced extensive ground damage over an irregular elliptical area around a hundred kilometres wide, and a few tens of kilometres long,[65] with the secondary effects of the blast being the main cause of the considerable number of injuries. With a total mass of 654 kg (1,442 lb), this is the largest found fragment of the Chelyabinsk meteorite. ��!W���_��Å��[=Am]D���%�W�=�A�zĠPb�=:j��emM�|���{�Wվr�3�/%W��2h��Hm�0�{R_#dJ;��ki]���qz�!���x��5Q���� {��!g{��LG #�S���h�0r���@��Fcjq*gXJ���-HuC���$E��+XV����u?��6��b{�!�ѤU�\�� h�x1��r�R�j@�!0�S"�0&4�CC��F4Z����]�00A��#. A meteor ripped across the sky in central Russia on Friday, injuring hundreds. [98], Following an operation lasting a number of weeks, it was raised from the bottom of the Chebarkul lake on 16 October 2013. [47] The object did not release all of its kinetic energy in the form of a blast wave as some 90 kilotons of TNT (about 3.75 × 1014 joules, or 0.375 PJ) of the total energy of the main airburst's fireball was emitted as visible light according to NASA's Jet Propulsion Laboratory,[1][48] and two main fragments survived the primary airburst disruption at 29.7 kilometres (18.5 mi); they flared around 24 kilometres (15 mi), with The majority of the patients were suffering from cuts. [110] The radiant was close to the Eastern horizon where the Sun was starting to rise. The documentary also discussed the much greater tragedy "that could have been" had the asteroid entered the Earth's atmosphere more steeply. This was the biggest impact over land since the poorly observed Tunguska impact in 1908, for which kinetic energy estimates range from 3 … [citation needed] Most of the injuries were caused by the secondary blast effects of shattered, falling or blown-in glass. “This data is significant because it shows that, even though the asteroid fell to Earth already severely weakened and its smaller fragments limited the damage on the gr… stream [71] Office buildings in Chelyabinsk were evacuated. The Chelyabinsk meteor was a superbolide that entered Earth's atmosphere over Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC). mid-August 1953 initial attempt at a thermonuclear device. Karbysheva, who remained standing, was seriously lacerated when the blast arrived and window glass severed a tendon in one of her arms and left thigh; none of her students, whom she ordered to hide under their desks, suffered cuts. From Wikipedia, the free encyclopedia Not to be confused with Chelyabinsk meteor. In the city of Chelyabinsk alone, more than 3,500 buildings were damaged, and the researchers found shockwave destruction as far as 100 kilometers away from the impact site. �&�������OV�J\����ph�2��B��}�8ӽ��cA���g����_�WV*��E��O�v_3�ywކ+Z �R�4��LD��vE� �+�ŧ�3��q*6G(�� �g�flaJ@�cB�[�Z��n��ajwb��8��Y϶ٹ�fA�:�������*,��x�#�\�ڢ:����7�7߼������˷��� � 7�/A�~�⇲�����p���;,���-;��qZ��a7n����iX�V�A ��?���g {Z�Gsz��ͿN\?��a�p��(����؏/������^�_�q������O�~��(��[�=��n�n���W`S�����Aj����{��r)z���XH����3$q$n��+KD\yI�� A blinding flash, a loud sonic boom, and shattered glass everywhere.
