A group of scientists has found this weekend the first fragments of the meteorite that fell on Friday on Russia and caused more than half a thousand injured. An expedition of the Urals Federal University found in the vicinity of Lake Chebarkul, located in the southwest of the country, and has drawn its first conclusions: "It is an ordinary chondrite," said Viktor Grohovsky, which means that it is a common type of space rock.
According to NASA, the meteorite about 17 meters in diameter and a mass of 10,000 tonnes, went through the Earth's atmosphere at a speed greater than the speed of sound and disintegrated into several pieces that crossed the sky ablaze. The fragments fell on three Russian regions, Chelyabinsk, Sverdlovsk and Tyumen, and Kazakhstan, following an explosion that could be detected in Alaska and a tremor equivalent to an earthquake, sparking panic among the local population. The fact that disintegrated as it did was because a track on its composition, it was not iron / nickel, which confirm these initial analyzes. Scientists have already categorically ruled out that this rock had to do with the asteroid 2012 DA14, three times larger than a few hours passed within 28,000 kilometers of Earth's surface and whose career was well known in advance.
The greatest damage from the meteorite occurred in the city of Chelyabinsk, where, according to the latest report from the Ministry of Health, there were 1,200 wounded, of whom 52 remain hospitalized, 12 in serious condition. As for damage, officials estimate 25 million in economic losses.
