Is there a danger that the human race will be destroyed by the collision of the meteorite?

Meteorite collision with the Earth's dinosaurs of mass extinction is believed to have caused the, and the evidence " traces of the mass extinction caused a huge meteorite dinosaur " is still trapped in the Yucatan Peninsula of Mexico. The collision of the meteorite will drastically change the global environment to extinct the dinosaurs who were extremely prosperous at the time, but even in the modern age of the 21st century "there is certainly a possibility that the meteorite collides with the earth" And science media Popular Science wrote.

Earth has been hit by meteorite collisions many times, including cases that were born 4.6 billion years ago, and cases where dinosaurs were extinct 65 million years ago. NASA is monitoring the 18,000 asteroids that are thought to have the potential to hit the Earth, and its diameters vary from just 3 feet (about 90 cm) to 3000 feet (about 900 m).
Basically, if the diameter of the meteorite is less than 100 feet (about 30 m), it is believed that the meteorite explodes in the air before colliding with the ground. In this case there is no possibility that a huge crater will be made on the ground, but there is a possibility that the shock wave produced by the meteorite could cause a major damage such as cracking the window.
One example is the case of a falling meteorite incident in Chelyabinsk , Russia in 2013. In Cheyabinsk's meteorite fall, a large number of people have witnessed the appearance of a meteorite fall and in the movie photographed at that time, it can be confirmed that the falling meteorite emits intense light. Although the meteorite exploded and crushed in the air, the sonic boom generated by the meteorite broke many window glasses and rolled people, and indeed nearly 1,500 injured people came out. At this time the diameter of the fallen meteorite is seen to be around several meters to 15 meters.

Although we do not mysteriously encounter meteorite collisions, we are worried about how much damage is caused by the meteorite of what diameter on earth. Therefore, the figure showing the meteorite diameter (1 foot = about 30 cm) and the expected collision energy (1 MT ) and the average falling frequency of the meteorite is shown. The 16 feet (4.9 m) diameter meteorite at the top of the figure has an explosive power of roughly 0.01 MT, which is equivalent to about 10 thousand tons of trinitrotoluene (TNT) explosive, and this level of meteorite has an average It is said that it will fly to the earth once a year.
It is 33 feet (about 10 m) meteorite that has energy equivalent to that of the meteorite that fell to Chelyabinsk, and the energy when colliding is 0.1 MT (TNT explosive 100 thousand tons), the average frequency of flight to the earth is Once in about ten years. Even meteorites of this size have collision energies of dozens of times that of atomic bombs ( Little Boy ) dropped in Hiroshima.
A meteoroid with a diameter of 3300 ft (about 1 km) is thought to fly once in about 700 thousand years, and it is said that garbage rolled up by the collision covers the entire earth and the sun's light is obstructed . Also, a meteorite with a diameter of 6 miles (about 10 km) that flying at a rate of about one hundred million years is about the same as a meteorite that extincts dinosaurs, and if colliding, many of the lives existing on the earth are extinct It seems to be done. The most frequent occurrence of such a huge meteorite falling to the earth is not so high, so it seems that there is little possibility that the meteorite will collide and extinct while mankind lives.

The impact of the actually falling meteorite depends on the falling speed and material of the meteorite. The faster the speed of entering the earth the faster the meteorite becomes, the more powerful the meteorite will melt and melt rocks on the ground surface and make huge craters. The speed of the meteorite fall can reach up to 44,000 miles per hour (about 70,000 km / h) at the maximum. The meteorite is likely to be burned out in the atmosphere, as the meteorite is more likely to have meteorites reaching the surface as the more metallic it is.
And as the biggest factor determining the damage of falling the meteorite, the place where it falls will be involved. If a meteorite falls into an urban area where many people live, the damage by the meteorite itself or shock wave may be enormous, but if it drops to the ocean occupying 70% of the earth's surface, the damage will be on the ground There is a high possibility that it will be less than falling. Some people are worried about the damage of the tsunami caused by a meteorite collision, but the danger is even higher than that due to a high energy meteorite striking the ocean floor and rolling up a large amount of dust into the atmosphere Researchers think that it is climate change.
