Meteors fell into Russia weighing 10,000 tons

The meteorite falling into the Russian Ural region has been recalculated by NASA based on the latest data, with a mass of about 10,000 tons and a destructive power of up to 500 kiloton.

According to new data collected by the US aerospace agency (NASA), the estimated size of the object before falling into the Earth's atmosphere is 17m (instead of 15m as previously calculated), with mass 10,000 tons. The energy generated in this case increased from 30 kiloton (according to initial estimates) to nearly 500 kiloton.

NASA also said this meteorite is not related to the 2012 meteorite DA14 is approaching Earth."The orbit of Russian meteorites is very different from the trajectory of 2012 DA14 meteorite, so it is a completely unrelated object , " NASA wrote on the website.

After the meteorite explosion took place in Russia, many people in Cuba and the state of California, USA also reported seeing similar fireballs but smaller than fruit in Russia flying through the sky.

California residents say they shudder when they see an unusual light on San Francisco Bay a few hours after the Russian meteorite explosion. Based on the 35 reports received by the American Meteorological Society, light in the northern California sky is discrete meteor shower, not serious, according to Mike Hankey, the association's manager."The fireballs fall every night, around the world," AAP quoted him as saying.

In the city of Rodas, central Cuba, residents said on the 12th of February they saw "light trails in the sky and then a big fireball bigger than the sun" . The explosion caused "my house to shake completely," a local resident said in a clip released on Feb. 15 on Cuban website.

Experts believe that small meteorites fall to Earth 5 to 10 times each year. But the possibility of a large-scale meteorite explosion caused about 1,000 people injured in Russia to happen only once in at least 100 years.
