Get yours today!<\/p>\n<h3>Chelyabinsk: a mid-sky asteroid explosion<\/h3>\n<p>On February 15, 2013, a small asteroid with an estimated size of 65 feet (20 meters) entered Earth\u2019s atmosphere. It was moving at 12 miles per second (~19 km\/sec) when it struck the protective blanket of air around our planet, which did its job and caused the asteroid to explode. The bright, hot explosion took place only about 20 miles (30 km) above the city of Chelyabinsk in Russia and carried 20 to 30 times the energy of the Hiroshima atomic bomb. Its shock wave broke windows and knocked down parts of buildings in six Russian cities; furthermore, it caused some 1,500 people to seek medical attention for injuries, mostly from flying glass.<\/p>\n<figure id=\"attachment_160678\" aria-describedby=\"caption-attachment-160678\" style=\"width: 580px\" class=\"wp-caption aligncenter\"><figcaption id=\"caption-attachment-160678\" class=\"wp-caption-text\">Bright fireball over Russia on the morning of February 15, 2013. Scientists later said the light from the Chelyabinsk meteor was brighter than the sun. People saw it up to 60 miles (100 km) away.<\/figcaption><\/figure>\n<h3>The power of the Chelyabinsk explosion<\/h3>\n<p>Large and small bodies from space strike Earth\u2019s atmosphere continuously. The Nuclear Test Ban Treaty Organization operates a network of sensors that monitors Earth around the clock listening for the infrasound signature of nuclear detonations. In 2014 it stated that the sensors had recorded 26 atom-bomb-scale asteroid impacts to Earth\u2019s atmosphere since 2000. <\/p>\n<p>Still, the February 15, 2013, Russian superbolide was extremely powerful; in fact, it was the most powerful explosion caused by an asteroid since Tunguska. The Tunguska event flattened a wide area of forest and killed reindeer in Siberia in 1908.<\/p>\n<p>The Tunguska event happened in a sparsely populated part of Siberia; therefore, it remained mysterious to scientists throughout the early part of the 20th century. By contrast, across a wide swath of Russia on February 15, 2013, numerous dashboard cameras and amateur photographers captured images of the incoming meteor and its effects.<\/p>\n<figure id=\"attachment_536214\" aria-describedby=\"caption-attachment-536214\" style=\"width: 800px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/earthsky.org\/upl\/2026\/02\/Chelyabinsk_Asteroid_pillars-February-15-2013-ESA.jpg\" alt=\"Long, narrow, bright line of cloud above snowy scene with line of bare trees.\" width=\"800\" height=\"285\" class=\"size-full wp-image-536214\" srcset=\"https:\/\/earthsky.org\/upl\/2026\/02\/Chelyabinsk_Asteroid_pillars-February-15-2013-ESA.jpg 800w, https:\/\/earthsky.org\/upl\/2026\/02\/Chelyabinsk_Asteroid_pillars-February-15-2013-ESA-300x107.jpg 300w, https:\/\/earthsky.org\/upl\/2026\/02\/Chelyabinsk_Asteroid_pillars-February-15-2013-ESA-768x274.jpg 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\"\/><figcaption id=\"caption-attachment-536214\" class=\"wp-caption-text\">Vapor cloud trail left by the Chelyabinsk, Russia, asteroid as captured by M.

An informal market emerged for meteorite fragments. <\/p>\n<p>A large number of small meteorites fell on areas west of Chelyabinsk, and, within hours of the visual sighting of the meteor, a 20-foot (6-meter) hole was discovered on the frozen surface of Lake Chebarkul in the Russian Ural Mountains. Scientists from the Ural Federal University collected 53 samples from around the hole that same day. <\/p>\n<p>In June 2013, Russian scientists reported further investigation by magnetic imaging below the location of the ice hole in Lake Chebarkul. They identified a larger meteorite buried in sediments on the lake floor. <\/p>\n<p>Following an operation lasting a number of weeks, on October 15, 2013, the scientists pulled up a large fragment of the meteorite from the bottom of Lake Chebarkul. It had a total mass of 1,442 pounds (654 kg) and to date remains the largest found fragment of the Chelyabinsk meteorite. <\/p>\n<figure id=\"attachment_184291\" aria-describedby=\"caption-attachment-184291\" style=\"width: 580px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-184291\" alt=\"People standing around, two men tugging large tarp with big black rock on it.\" src=\"https:\/\/earthsky.org\/upl\/2013\/10\/Chebarkul-meteorite.jpg\" width=\"580\" height=\"374\"\/><figcaption id=\"caption-attachment-184291\" class=\"wp-caption-text\">This is the largest-discovered fragment of the Russian meteorite, lifted from the bed of Lake Chebarkul in the Urals.
