Russian meteorites leave hundreds of tons of dust in the atmosphere

The 11,000-ton meteorite exploding in the Russian sky in February left behind a layer of dust weighing hundreds of tons in the earth's atmosphere. This dust has moved around the planet in just four days.

The blazing meteorite in the sky of Russia Chelyabinsk made more than 1,200 people injured in February. The window of over 900 schools and hospitals broke, about 100,000 buildings were damaged.

According to Space.com, research by the US Aerospace Agency (NASA) shows that it leaves in the atmosphere a hundred tons of dust, suspended for at least three months before dissolving.

NASA expert Nick Gorkavyi and colleagues tracked this dust just four hours after the meteorite explosion in Russia. They found it hovering at a height of 40km and moved east at a speed of more than 300km / h.

After a day, heavy dust particles fell to the ground, however lighter particles continued to move eastward at an increased speed. And after only four days, the dust had traveled around the globe and returned to the correct city of Chelyabinsk. Three months later, the dust still exists and floats in the atmosphere.

NASA experts said that despite the accumulation, this dust does not cause any environmental impact on the earth. It is estimated that every day 30 tons of dust from the universe falls into the earth. Volcanoes and other natural phenomena also spray a lot of dust into the atmosphere.

However, NASA experts claim this observation is useful . 'The Chelyabinsk meteorite is much smaller than the meteorite that destroyed the dinosaurs 65 million years ago. With this meteorite, we had a great opportunity to study an extremely dangerous phenomenon, ' said Gorkavyi expert.
