  • Fragments of the meteorite have been found along a 50 kilometer (30 mile) trail under the meteorite’s flight path
  • Small meteorites have also been found in an eight-meter (25 feet) wide crater in the region’s Lake Chebarkul
  • believes there are more to be found, including a possible biggest chunk that he says may lie at the bottom of Lake Chebarkul. It could be up to 60cm in diameter

  • traveled through the atmosphere for about 30 seconds before breaking apart and producing violent airburst ‘explosion’ about 20-14 km (12-15 miles) above Earth’s surface
  • producing an energy shockwave equivalent to a 300 kilotons explosion
  • The Russian meteor is the largest reported since 1908, when a meteor hit Tunguska, Siberia
  • ...3 more annotations...
  • Tunguska event was caused by an object about the size of 2012 DA14
  • The meteor, which was about one-third the diameter of asteroid 2012 DA14, became brighter than the Sun
  • Its trail was visible for about 30 seconds, so it was a grazing impact through the atmosphere

  • Scientists have begun piecing together the characteristics of the meteor that exploded over Russia on the morning of February 15, using data from seismic instruments that track earthquakes and microphones designed to detect sonic booms from nuclear explosions
  • The explosion had the equivalent of up to 500,000 tons of TNT
  • about 30 times the energy output of the Hiroshima atomic bomb
  • ...1 more annotation...
  • only 5 percent of the energy of the famous 1908 Tunguska meteor that downed trees over a 2,000-square-kilometer area in Siberia

  • 16 February 2013
  • NASA revised its estimates on the size and power of the devastating meteor explosion
  • now thought to be slightly larger — about 55 feet (17 m) wide — with the power of the blast estimate of about 500 kilotons, 30 kilotons higher than before
  • ...6 more annotations...
  • also substantially more massive than thought
  • Initial estimated pegged the space rock's mass at about 7,000 tons
  • the meteor weighed about 10,000 tons and was travelling 40,000 mph (64,373 km/h) when it exploded
  • new estimates were generated using new data that had been collected by five additional infrasound stations located around the world
  • the first recording of the event being in Alaska, over 6,500 kilometers away
  • infrasound stations detect low-frequency sound waves that accompany exploding meteors, known as bolides

  • The fall of such a large meteor estimated as weighing dozens of tonnes was extremely rare
  • 950 people were injured, with two-thirds of the injuries light wounds from glass shards and other materials blown out by the shockwave
  • the ministry saying almost 300 buildings were damaged including schools, hospitals, a zinc factory and even an ice hockey stadium

  • At 9:20 am (0320 GMT), an object was observed above Chelyabinsk which flew by at great speed and left a trail behind. Within two minutes there were two bangs," regional emergencies official Yuri Burenko
  • office of the local governor said that a meteorite had fallen into a lake outside the town of Chebarkul in the Chelyabinsk region and television images pointed to a six-metre (20-foot) hole in the frozen lake's ice
  • it has yet to be finally confirmed if meteorite fragments made contact with the Earth and there were no reports that any locals had been hurt directly by a falling piece of meteorite
  • the shock wave blew out windows amid temperatures as low as minus 18 degrees Celsius (zero degrees Fahrenheit
  • Russian Academy of Sciences
  • estimated the body to be several metres long and weighing several dozen tonnes
  • The meteor explosion appears to be one of the most stunning cosmic events above Russia since the 1908 Tunguska Event

  • Just a week after a huge fireball streaked across the skies of the Chelyabinsk region of Russia, astronomers published a paper that reconstructs the orbit and determines the origins of the space rock
  • University of Antioquia in
  • Colombia used a resource not always available in meteorite falls: the numerous dashboard and security cameras that captured the huge fireball
  • ...9 more annotations...
  • Using the trajectories shown in videos posted on YouTube, the researchers were able to calculate the trajectory of the meteorite as it fell to Earth and use it to reconstruct the orbit in space of the meteoroid before its violent encounter with our planet.
  • The results are preliminary
  • and they are already working on getting more precise results
  • But through their calculations, Zuluaga and Ferrin determined the rock originated from the Apollo class of asteroids
  • due to variations in time and date stamps on several of the videos
  • some which differed by several minutes
  • they decided to choose two videos from different locations that seemed to be the most reliable
  • used this data and Google Earth to reconstruct the path of the rock as it entered the atmosphere and showed that it matched an image of the trajectory taken by the geostationary Meteosat-9 weather satellite.
  • From triangulation, they were able to determine height, speed and position of the meteorite as it fell to Earth

  • Russian scientists appear to have pulled up a half-ton charred meteorite from the bottom of a murky Siberian lake
  • a piece of the giant space rock that exploded in the skies above the southern Urals in February.
  • Entering the atmosphere at speeds up to 31,000 miles per hour (50,000 kilometers per hour), the Russian meteor, officially named 2011 EO40, exploded about 25 miles (40 kilometers) above the city of Chelyabinsk
  • ...5 more annotations...
  • The power of the explosion was estimated to be at least 20 times stronger than the atomic bomb dropped on Hiroshima in 1945
  • The resulting air blast damaged buildings and injured some 1,600 people.
  • piece of meteor recovered this week weighs at least 1,257 pounds (570 kilograms).
  • , it is only a fragment of the original impactor that is estimated to have been about 17 meters (54 feet) across, with a mass of about 10,000 metric tons before it shattered
  • locals directed scientists to Lake Chebarkul—45 miles west of the city of Chelyabinsk—to a 25-foot (8-meter) hole punctured in the ice by the meteor
