February 14, 2015 at 12:39Two years after the fall, the weight of the main fragment of the Chelyabinsk meteorite was 503.33 kg
The largest fragment of the Chelyabinsk meteorite, located in the regional museum of the region, was weighed on high-precision electronic scales. Three weighings were carried out, the arithmetic average of the results of which was 503 kilograms with twelve triples after the decimal point. Weight decreased by 1.6 kg compared with data for January 26.
A meteorite fell to Earth on February 15, 2013.
The Chelyabinsk meteorite fell to Earth in February 2013, causing explosions in the atmosphere and falling fragments in the Chelyabinsk region. The blast wave affected 1,147 people, including 259 children. A cloud of ten thousand tons of pollutants - compounds of iron, silicon, aluminum, magnesium and others - circled the planet several times.
Scientists are tryingfind answers to two basic questions: what is the nature of dark spots and stripes in the meteorite, and what events preceded its fall. In 2018, for the first time in 80 years, Moscow will host a congress of the International Meteorite Society, within which they will conduct an excursion to the places of impact and storage of the Chelyabinsk meteorite.
More than four hundred videos made by car DVRs and surveillance cameras collected 138 million views in the first 72 hours.
Large fragments were raised in October 2013 from the bottom of Lake Chebarkul. The first weighing of the largest fragment was made on a truck scale, which broke during the procedure. The result, according to witnesses, amounted to 654 kilograms. Later, a hundred-kilogram piece broke off from the fragment and the moisture evaporated. On February 9, 2015, the meteorite was weighed on a high-precision electronic scale with a carrying capacity of 10 tons, the average result after three weighings was 503.333333333333 kilograms. In the future, the weight of Chelyabinsk will change : evaporation of moisture can cause its decrease, and oxidation in the object will increase.
