How did the earth's overlord dinosaurs die out? One of the most popular theories is that 65 million years ago, an asteroid hit the earth, causing climate defecation and killing a variety of creatures, including dinosaurs. In this way, what if human society is hit by an asteroid? Let alone, there is a chance in 2022, though only 0.026% chance.

NASA's national space agency said recently,An asteroid named JF1 will approach earth on May 6, 2022With a diameter of about 130 meters, the impact force on the earth is equivalent to 230000 tons of TNT explosive, similar to that of 15 atomic bombs thrown by the United States at Japan in 1945.

If the asteroid hits a densely populated area, it may cause millions of deaths. Even if it lands in the uninhabited Pacific Ocean, it may also cause natural disasters such as tsunamis. In any case, there is a sense of the end of the world in the movie the day after tomorrow.

However, such a worry is necessary in science, but in reality, you don't need to think too much,Because it has a 0.026% chance of hitting the earthThis kind of small probability is almost impossible in daily life. 99% of the possibility is that this asteroid will not have any impact on the earth.

The asteroid impact on the earth must have experienced many times in the 4.6 billion years of the earth. Scientists point out that it will happen once every millions of years. However, in the short history of human civilization, it is unlikely to encounter an asteroid impact on the earth or even bring destruction. In addition to the impact on the earth in 2022, there will be another asteroid 99942 Apophis with a diameter of 230 meters running to the earth in 2029 Ball, but it will only be in April 13 that year from the earth 31, 000 kilometers away from the shoulder.
