A huge fireball lit up the sky over southwest China on Wednesday. The Earth's atmosphere meteoroid entered and rage, burned.
Information NASA shows that the speed of the fireball was 14.6 km per second, making the impact energy is equal to 540 tons TNT equivalent. The explosion in the night sky occurred near the border of Myanmar.
The cosmic light show was visible for a few seconds to 20 PM local time on Wednesday. Videos posted on Chinese social networks, has recorded this extraordinary spectacle.
The largest fireball in China was seen in 2009, when a meteor broke through the atmosphere, producing 2.3 million tons of TNT equivalent impact energy.
NASA defines a fireball as "exceptionally bright meteors which can be seen on a very wide territory." Meteor is the phenomenon generated when meteoroid — small fragments of asteroids or comets — enter the Earth's atmosphere.
"The objects that become fireballs, can exceed one meter in diameter," says NASA. But usually they are big enough to survive a devastating journey through the Earth's atmosphere.
The visual effect is created when the object enters the atmosphere and at the same time slowed and heated by atmospheric friction. Before him formed a shock wave front when the atmospheric gases are compressed and heated.
According to the data tables of NASA, the last fireball of the same size broke out in June when the meteoroid made impact energy the amount of 520 tons of TNT. Then the object entered the atmosphere off the coast of Eastern Russia.
