If you weigh 120 pounds, you would weigh only 20 pounds on the moon. For that reason, the Chelyabinsk impact event is incredibly important: It produced the first high-precision values for the energy of a blast and the ground damage it caused. One of the fragments that struck near Chebarkul left a crater six meters in diameter. The meteor's entry into the atmosphere causes a bright streak of light, described by many as brighter than the sun.

Around 1,200 people have sought medical attention in Chelyabinsk alone because of the disaster, the official website of regional governor Mikhail Yurevich reported. February 15, 2013 will be remembered as the day the sky exploded over Russia. The considerable uncertainty in estimates of the energy of those and other relatively small impact events makes it difficult to quantify future hazards. Winds in excess of 1500 km/h were produced within the inner 6-km-diameter zone and still exceeded 100 km/h at radial distances of 20 km. The day the Chelyabinsk meteorites arrived. Some of the pieces showed remarkable shock features. Shook my whole building and woke me up!#челябинскyoutube.com/watch?v=4ZxXYs…. The third site was found some 80 kilometers further to the northwest, near the town of Zlatoust. But how do we know? A small asteroid entered the atmosphere traveling at tremendous speed. That breathtaking impact site was produced by a roughly 30-m-diameter iron asteroid, remnants of which are known as the Canyon Diablo meteorites. The blast was immediately lethal for human-sized animals within 6 km of it. It was squeezed until it could not stand the pressure and exploded. Fortunately, Earth’s atmosphere screens most objects from reaching the surface with cosmic velocities. The left showing the external fusion crust and the slice on the right showing the internal structure. Like all new fallen ordinary chondrites the meteorites were covered with a black fusion crust. Army units found three meteorite debris impact sites, two of which are in an area near Chebarkul Lake, west of Chelyabinsk.
Although stony near-Earth asteroids dominate the impact flux, nearly all of the smallest craters on Earth were produced by iron asteroids. This website uses cookies. Some of those rocks are thought to be meteorites. A blinding flash, a loud sonic boom, and shattered glass everywhere. Chelyabinsk Meteorite Background: February 15, 2013 will be remembered as the day the sky exploded over Russia. The pressure pulse and airblast can be devastating. The meteor traveled some 200 miles through the atmosphere before vaporizing in an explosion that shattered windows and set off car alarms. Hundreds have sought medical attention for minor injuries. On same day as the Chelyabinsk meteor – February 15, 2013 – the asteroid 2012 DA14 was still approaching Earth. A 52-year-old woman who suffered a spinal fracture will be … We are a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for us to earn fees by linking to Amazon.com and affiliated sites. Do you think you have found a meteorite?
Some objects are large enough and strong enough, however, to penetrate deeply into the atmosphere before exploding in an airburst or reaching Earth’s surface to produce a crater. This means that every time you visit this website you will need to enable or disable cookies again. Photos of the meteor, fragments, and a microscopic view of the interior of the meteorite can be found in the full article.

Russia’s Urals region has been rocked by a meteorite explosion in the stratosphere. Small stony asteroids, like Chelyabinsk, preferentially produce airbursts before reaching the ground. A small asteroid entered the atmosphere traveling at tremendous speed. The most famous is the 49 000-year-old Barringer meteorite crater in northern Arizona. It was squeezed until it could not stand the pressure and exploded. If you disable this cookie, we will not be able to save your preferences.
