Chelyabinsk: a mid-sky asteroid explosion Its shock wave broke windows and knocked down parts of buildings in six Russian cities; furthermore, it caused some 1,500 people to seek medical attention for injuries, mostly from flying glass. Bright fireball over Russia on the morning of February 15, 2013.
What is the Chelyabinsk meteor made of?
He says the fragments — pieces from the outer portion of the meteor itself which streaked across the Russian sky on February 15, 2013 — are typical of more stony-type meteorites and made up of some 90 percent silicate; five percent sulfide; and five percent iron-nickel.
Did Chelyabinsk meteor hit the ground?
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.
Where did the Chelyabinsk meteor come from?
15. The large fireball (technically, called a “superbolide”) observed on the morning of Feb. 15, 2013, in the skies near Chelyabinsk, Russia, was caused by a relatively small asteroid approximately 17 to 20 meters in size (about 18.6 to 21.9 yards) that entered Earth’s atmosphere at high speed and at a shallow angle.
Where did the Chelyabinsk meteor hit?
Russia
The Chelyabinsk meteor was a superbolide that entered Earth’s atmosphere over the southern Ural region in Russia on 15 February 2013 at about 09:20 YEKT (03:20 UTC).
Where did the Chelyabinsk meteor explode?
The Chelyabinsk meteor was a small asteroid — about the size of a six-story building — that broke up over the city of Chelyabinsk, Russia, on Feb. 15, 2013. The blast was stronger than a nuclear explosion, triggering detections from monitoring stations as far away as Antarctica.
What damage did the explosion over Chelyabinsk cause?
The blast was stronger than a nuclear explosion, triggering detections from monitoring stations as far away as Antarctica. The shock wave it generated shattered glass and injured about 1,200 people. Some scientists think the meteor was so bright it may have briefly outshone the sun.
How much damage did the Chelyabinsk meteor do?
The house-sized asteroid entered the atmosphere over Chelyabinsk at over eleven miles per second and blew apart 14 miles above the ground. The explosion released the energy equivalent of around 440,000 tons of TNT and generated a shock wave that blew out windows over 200 square miles and damaged some buildings.
What is the Chelyabinsk meteorite?

What is a meteorite in geography?
Meteorite, any fairly small natural object from interplanetary space—i.e., a meteoroid—that survives its passage through Earth’s atmosphere and lands on the surface. In modern usage the term is broadly applied to similar objects that land on the surface of other comparatively large bodies.
Did meteorites cause the K–T extinction?
An investigation into the theory that meteorites caused the K–T extinction. Meteorite, any fairly small natural object from interplanetary space—i.e., a meteoroid —that survives its passage through Earth’s atmosphere and lands on the surface.
What is a meteorite fragment?
In modern usage the term is broadly applied to similar objects that land on the surface of other comparatively large bodies. For instance, meteorite fragments have been found in samples returned from the Moon, and the robotic rover Opportunity has identified at least one meteorite on the surface of Mars.
