Incident with a meteorite that had happened in the morning February 15, 2013 , compared with a fall of the Tunguska meteorite in 1908. However, the size of the current and historical "space aliens" are not comparable, and therefore the destruction of the very different.
Scientists are trying to calculate the trajectory of the meteorite to its collision with the Earth. This will help to find his large pieces, and for them to learn more about the solar system. After analyzing the photos and videos of the witnesses, the researchers made several conclusions. Presumably, the body came out of the asteroid belt located between Mars and Jupiter , and initially weighed about 9000 tons.
The meteorite was visible at a distance of about 92 kilometers above the Earth. Then his speed was 17.5 miles per second. After about 11 seconds, already at an altitude of about 32 kilometers, it exploded, unable to withstand the air resistance. By the way, it has reduced the velocity of a falling object up to 180 meters per second. Because of the resulting blast wave among residents of Chelyabinsk and nearby communities took off the glass.
The team gathered by the Russian Academy of Sciences , has found more than 50 pieces of the heavenly bodies up to 1 cm in diameter each . Another group led by Victor Grochowski, a member of the Committee on Meteorites of the Academy of Sciences , found about the same number of fragments, but larger. One of them weighs about two pounds. The fragments were immediately sent to the Institute of Geochemistry and Analytical Chemistry. Vernadsky Sciences for further analysis.
The results showed that the meteorite, which consists mainly of stone with a small metal inclusions is chondrite - the most common type of meteorites that fall to Earth. Timothy Spar ( Timothy Spahr ), director of the Astrophysical Observatory in Cambridge, minor planets, explains, "rather Chondrites strong, and may reach the Earth's surface in a consistent state, but specifically this one, most likely, not once encountered with other celestial bodies, which is why he broke up in the atmosphere into small pieces. "
The calculations showed that the most likely pieces weighing about 10 kilograms are in the village herbalist.
So far, the most mysterious object of study is a hole with a diameter of 6 meters in an ice crust on Lake Chebarkul. Divers are already investigating this area for finding a meteorite at the bottom of the lake. Timothy Spar is skeptical: "It's not like the hole was made by a heavenly body. Looks more like someone cut it with an ax."
Meanwhile, studies continue to Chelyabinsk meteorite, scientists hope to learn more about why he fell and landed from the planet. All Russian citizens, have been falling meteorite, scientists are asked to complete a form on a specially created website . The collected data will help researchers to recover the fate of "comic wanderer".
