Six years earlier today, a tiny asteroid v an estimated size of 65 feet (20 meters) entered Earth’s atmosphere. The February 15, 2013, asteroid was moving at 12 miles per second (~19 km/sec) once it win the protective blanket of air about our planet, which walk its job and caused the asteroid to explode. The bright, hot explosion took place only around 20 mile (30 km) over the city of Chelyabinsk in Russia and carried 20 come 30 time the power of the Hiroshima atomic bomb. That shock wave damaged windows and also knocked down parts of buildings in six Russian cities and also caused part 1,500 world to seek clinical attention for injuries, greatly from paris glass.

Large and little bodies from space strike Earth’s environment continuously. The nuclear Test half Treaty Organization, i beg your pardon operates a network the sensors that monitors Earth about the clock listening for the infrasound signature of atom detonations, claimed in 2014 the it had recorded 26 atom-bomb-scale asteroid effects to Earth’s atmosphere due to the fact that 2000.
Still, the February 15, 2013, Russian superbolide was incredibly powerful. It was later on said to be the most powerful explosion resulted in by one asteroid because the Tunguska event, which flattened a broad area that forest and killed reindeer in Siberia in 1908.
The Tunguska event happened in a sparsely populated part of Siberia. It continued to be mysterious to scientists throughout the early part of the 20th century. By contrast, throughout a vast swath of Russia on February 15, 2013, dashboard cameras and also amateur photographers captured images the the incoming meteor.Bright fireball end Russia top top the morning the February 15, 2013.

Scientists from the Ural commonwealth University gathered 53 samples from about the hole that same day.
In June 2013, Russian scientists reported further investigation through magnetic imaging listed below the ar of the ice hole in Lake Chebarkul. Lock had determined a larger meteorite hidden in sediments ~ above the lake floor.
Following an procedure lasting a number of weeks, top top October 15, 2013, a large fragment the the meteorite to be lifted indigenous the bottom the Lake Chebarkul.
