In December 2018 off the coast of the Russian Kamchatka has happened over the last few years, the explosion of a meteorite
NASA explained that the meteorite entered the Earth’s atmosphere on December 18 around noon with a speed of 32 kilometers per second at a very small angle at seven degrees. The destruction of the meteorite with the formation of shock waves occurred at the height of 25.6 kilometers above the planet’s surface

In December 2018 off the coast of the Russian Kamchatka has happened over the last few years the explosion of the bolide (very bright and large meteor). However, it happened far away from settlements, so the “visitor” from outer space nearly didn’t notice, the BBC reports with reference to the employee’s planetary protection NASA’s Lindley Johnson.
Meteor the destruction of the atmosphere has allocated energy 10 times more than the atomic bomb dropped on Hiroshima. As Johnson explained, so the large asteroids fall on the Ground not more than two or three times in 100 years.
NASA said that the meteor entered the Earth’s atmosphere on December 18 around noon with a speed of 32 kilometers per second at a very small angle at seven degrees. The destruction of the meteor with the formation of shock waves occurred at the height of 25.6 kilometers above the planet’s surface. The power of the explosion amounted to 173 kiloton in a trotyl equivalent.
The explosion was allocated 40% of the energy of Chelyabinsk meteor falling to Earth in 2013. This time the disaster has happened over the Bering sea, so the public outcry the fall of the meteorite did not cause.
“This is another thing in our Arsenal of protection on the planet a lot of water,” said the Manager to monitor near-earth objects at NASA, Kelly Fast.
The explosion in the atmosphere was recorded by us military satellites, and then the Pentagon gave information about the incident to NASA. Also a meteor captured on camera Japanese satellite Himawari.
We will remind, the largest in recent years, the meteorite fall recorded in the Chelyabinsk region. A celestial body collided with Earth 15 Feb 2013. The size of the asteroid was about 19.8 meters in diameter and weight is 13 tons. With the destruction of the meteor in the atmosphere formed shock wave with a power of about 440 kilotons of TNT. Injured 1,5 thousand inhabitants. October 16, the largest fragment of the meteorite weighing about 600 pounds was raised from the mud at the bottom of lake Chebarkul with a depth of approximately 20 meters.
In 2005, the U.S. Congress commissioned NASA to reveal 2020, 90 percent of the asteroids that could collide with Earth and have dimensions of 140 metres in diameter. Such space objects can cause serious damage to the whole region. However, scientists believe that the fulfillment of the congressional task will take about another 30 years.
