NASA told about the largest after the Chelyabinsk meteor explosion in Kamchatka, which no one noticed

The meteorite fell in the Bering Sea – far from people and residential areas.

In December 2018, the largest meteorite explosion occurred after the incident in Chelyabinsk in 2013. However, this happened away from people, so the phenomenon went almost unnoticed. This was told the “BBC” NASA planetary defense officer Lindley Johnson.

According to the agency, the meteorite during the destruction of the atmosphere released energy 10 times more than the atomic bomb dropped on Hiroshima. As Johnson explained, such large meteorites fall to Earth no more than two or three times in 100 years.

NASA said that a meteorite entered the Earth’s atmosphere on December 18 at a speed of 32 kilometers per second at a very steep angle of seven degrees. The destruction of the meteorite with the release of shock waves occurred at an altitude of 25.6 kilometers above the surface of the planet. The power of the “explosion” was 173 kilotons in TNT equivalent.

As in the case of Chelyabinsk, NASA did not know that a meteorite would fall on Kamchatka. The agency learned this from the US military, who spotted an explosion in the atmosphere from satellites.

The fall of the meteorite to Chelyabinsk took place on February 15, 2013. Then a celestial body with a diameter of 17 meters and a mass of about 10 thousand tons entered the earth’s atmosphere near the city. He was named the largest meteorite that fell to Earth after the Tunguska meteorite in 1908.

The meteorite collapsed as a result of braking and singled out shock waves with a power of about 440 kilotons of TNT. Due to the fact that the incident occurred during the day near a large city, it became one of the most documented cases of the fall of a large celestial body in history.
