Two years after the fall of the weight of the ground Chelyabinsk meteorite fragment was 503, 33 kg

The largest meteorite fragment "Chelyabinsk", located in the museum field, weighed on high-precision electronic scales. There were three weighing, the arithmetic mean of the results which amounted to 503 kilograms with twelve threes after the decimal point. Weight decreased by 1, 6 kg compared with the data for January 26.

Meteorite fell to Earth 15 February 2013.





Meteorite "Chelyabinsk" fell to Earth in February 2013, triggering explosions in the atmosphere and fall of the fragments in the Chelyabinsk region. From the blast suffered 1,147 people, including 259 children. Cloud of ten thousand tons of pollutants - compounds of iron, silicon, aluminum, magnesium and other - several times circled the planet.

Scientists are trying to find answers to two basic questions: what is the nature of dark spots and stripes in a meteorite, and what events preceded his downfall. In 2018 in Moscow for the first time in 80 years will pass Congress of the International Society of meteorite in which to take a tour of the crash site and storage meteorite "Chelyabinsk".

More than four hundred recordings made car video recorder and surveillance cameras, collected 138 million views in the first 72 hours.



Large fragments raised in October 2013 from the lake bottom Chebarkul. First weighing the largest fragment produced by truck scales, which broke down during the procedure. The result, according to witnesses, was 654 pounds. Later on the track broke stokilogrammovye piece and evaporate moisture. February 9, 2015 a meteorite weighed on high-precision electronic scales lifting capacity of 10 tons, the average result after three weighings made 503 333 333 333 333 kilograms. In the future, the weight of "Chelyabinsk" will vary : evaporation of moisture can cause its reduction, and oxidation in the object - an increase.
