"It struck Earth's atmosphere at 40,000 mph and broke apart about 12 to 15 miles above Earth's surface. "The asteroid was about 17 meters in diameter and weighed approximately 10,000 metric tons ," Peter Brown, a physics professor at Western University in Ontario, Canada, said in a statement. The infrasound (low-frequency) signature on the nuclear-detection network, which is operated by the Comprehensive Nuclear-Test-Ban Treaty Organization, was the largest ever detected.

The Russians' propensity for using dashboard cameras meant there was a treasure trove of videos of the meteor, as many cameras filmed the explosion while drivers were on the road.Ī 65-foot-wide (20 meters) asteroid exploded without warning over the Russian city of Chelyabinsk in February 2013, blazing a superbright trail across the winter sky. Meanwhile, experts reviewed several fragments and amateur videos of the explosion. "It's very exciting scientifically and for collecting, and luckily, it looks like there will be plenty of it." When he gave the interview, Farmer was preparing to leave for Russia to hunt for pieces of the Chelyabinsk meteor. "This is the biggest event in our lifetime," rock dealer Michael Farmer of Tucson, Arizona, told OurAmazingPlanet, a sister site to. At that same location, scientists spotted a hole in the ice that they thought could be traced back to the meteorite's impact. 18, 2013, the first reports came in that pieces had been found around Lake Chebarkul, 43 miles (70 km) north of Chelyabinsk. Just three days after the explosion, on Feb. In the days after the explosion, meteorite hunters worldwide rushed to the remote area to try to find pieces of the space rock (which exploded high up in the atmosphere).
