Around the world in just four days: How dust belt from the Russian meteor raced across the Earth at incredible speeds
The meteor created a 50-foot hole in a frozen lake near town of Chelyabinsk. Around 3.5 hours after the explosion, its dust belt moved east at 190 mph. In four days, the belt had snaked its way around the entire planet. It released 30 times more energy than the atomic bomb in Hiroshima.
The meteor that exploded over Russia in February caused a thin stratospheric dust belt that traveled around the world in just four days.
NASA satellites made the unprecedented measurements of the meteor which is thought to have released 30 times more energy than the atomic bomb that destroyed Hiroshima.
The meteor fireball measuring 18 meters across and weighing 11,000 metric tons, screamed into Earth’s atmosphere at 41,600 mph.
Satellite data from Nasa has revealed that that four days after the bolide explosion, the faster, higher portion of the plume (red) had snaked its way entirely around the northern hemisphere and back to Chelyabinsk in Russia
Meteor that crashed in Russia was part of a 656-foot wide asteroid that broke off during its orbit around Earth

The meteor fireball, pictured, that crashed into Russia in February was part of a 656-feet wide asteroid called 2011 EO40. Spanish astrophysicists analyzed fragments of the meteor and claim it came from the Apollo asteroid that regularly crosses passed Earth as it orbits the sun.
Experts say the meteor weighed 10,000 tonnes and was 55 feet wide. The rock created a 50-foot hole in a frozen lake near Chelyabinsk. Scientists have analyzed more than 53 tiny fragments of the meteor. It is thought to have been part of a large Apollo asteroid called 2011 EO40.
The meteor fireball that crashed into Russia in February was part of a 656-foot wide asteroid called 2011 EO40.
Spanish astrophysicists analysed fragments of the meteor that were scattered across the Russian town of Chelyabinsk, where the meteor landed, and claim it came from the large Apollo asteroid that regularly crosses passed Earth as it orbits the sun.
They added that the piece may have broken off because of the stress caused by the gravitational pull of the planets and the sun, or could have been caused by the asteroid hitting into something else during its orbit.
