Dust trail from Chebarkul meteorite disappears 3 months later

A dust trail from the Chebarkul meteorite got scattered to various parts of the globe and disappeared only three months later, according to NASA experts. According to data received from a NASA satellite, hundreds of tonnes of space dust caused by the 11,000-ton meteorite’s explosion in the atmosphere over Chelyabinsk stretched eastward at a speed of over 300 kilometers per hour. The meteorite with a diameter of about 17 meters entered the Earth atmosphere on February 15, 2013. It fell apart to numerous fragments some of which fell on the territory of the Chelyabinsk region. Astronomers believe that the Chebarkul meteorite was the biggest celestial body to have fallen down on Earth since the time of the Tunguska meteorite (1908).
