How did the earth overlord dinosaurs die out? One of the most popular claims before was that an asteroid hit the Earth 65 million years ago, resulting in great changes in the climate and the extinction of a variety of organisms, including dinosaurs. In this way, what if human society encounters an asteroid hitting the earth? Not to mention, there is really a chance in 2022, although it is only 0.026%.
Recently, NASA announced that an asteroid named JF1 will approach the earth on May 6, 2022, with a diameter of about 130 meters. The power of hitting the earth is equivalent to 230000 tons of TNT explosive, which is similar to the power of 15 atomic bombs thrown by the United States into Japan in 1945.
If this asteroid hits a densely populated area, it may cause millions of deaths. Even if it falls in the uninhabited Pacific, it may also cause natural disasters such as tsunami. In any case, it has the feeling of the end of the world in the film the day after tomorrow.
However, such concern is necessary in science, but in reality, you don't have to think too much, because the probability of it hitting the earth is only 0.026%. Such a small probability is almost impossible to occur in daily life, and 99% of the possibility is that the asteroid will not have any impact on the earth.
The asteroid collision with the earth must have experienced a lot in the earth's 4.6 billion years. Scientists point out that it occurs every few million years. However, in the human civilization of just thousands of years, it is unlikely that the asteroid collision with the earth will even bring destruction, except this one in 2022, In 2029, another asteroid 99942 Apophis with a diameter of 230 meters will also run to the earth, but it will only pass 31000 kilometers away from the earth on April 13 of that year.
