Meteors once fell into Vietnam

According to Deputy Director of the Institute of Geophysics, Dr. Le Huy Minh, meteorite falls nothing strange, in the past meteorite once fell into Vietnam.

Finding meteorite fragments in Vietnam

Talking to PV, Dr. Le Huy Minh said that meteorites falling into the Earth's atmosphere are relatively many phenomena. But falling to the ground like the case in Russia on February 15 is a rare thing. Because meteorites fall at high velocities, they will burn out in the atmosphere. Only large, unburnt meteors fall to the ground.

Meteor is also a form of fire meteorite when it falls into the atmosphere. It was meteorites of small size and mass, so they were burnt out on the way. Therefore, from the ground, humans can see a mark across the sky.

Large meteorites, moving at high speeds, produce shock waves that affect the environment. Specifically, the meteorite explosion in the Ural region (Russia) on February 15, shockwave broke the glass door, poured the construction . Another harm that meteorite can bring is the piece Meteorite bursts crashed into buildings or people. In the last Russian case, without this harm, only indirect effects from shock waves.

These tectite stones are a fragment of meteorite found in our country

The Deputy Director of the Institute of Geophysics said that in Vietnam in the past, there were also meteorites falling. Evidence is that tectite rocks can be found in Vietnam, such as Cao Bang and Yen Bai . with a wide variety of sizes and shapes. These are the fragments of meteorites that fall in Vietnam.

The size of the tectite stones is very small, the common shape is disk, spherical . The reason for the small size of stones, because these meteorites fly into the Earth's atmosphere, burn first when touching the ground. Only large samples do not burn out, the rest can explode into many small pellets, falling to the ground.

However, how meteorites fell into Vietnam at a specific time, impact, damage . Vietnamese scientists could not find the answer.'At present, our country's space science science has not yet developed, and there are no mechanical devices as well as scientists who specialize in this issue,' said Dr. Le Huy Minh.

Do not be confused

According to Dr. Le Huy Minh, no country in the world can predict the time and place of meteorites falling to the earth. Because meteors are very small objects flying in the universe, people do not observe them regularly so they cannot calculate the orbit and its rules. The last explosion in meteorite in Russia also has no predictable countries.

Countries with advanced space science have thought about how to observe Earth's atmosphere or space regularly. If a meteorite is found, a missile launcher can be used to change the trajectory or break its path. However, only the rich countries like Russia and the US have mentioned this method, others have not thought about it.

'Meteorites that fall to the surface of the earth can fall anywhere, not to exclude Vietnam or any other country. However, the earth's surface is very large, so the probability of falling into Vietnam is very small. Moreover, the meteorite falls in Russia on February 15 are rare, hundreds of years to see once. Therefore, people should not be confused, worried , 'said the Deputy Director of the Institute of Geophysics.

Dr. Minh also added that meteorites fall is a normal, unforeseen natural phenomenon that can occur at any time. In life there are hundreds, thousands of natural phenomena like that, there are unexplored phenomena. People should not see the direction of superstition 'superstition '.
