Will the earth be hit by an asteroid? What are the chances? Are there enough earth resources?

There are many stars in the whole universe, some in their own orbits, some out of control and floating constantly. In the process of floating, it is likely to affect other planets. The earth is protected by the moon and Jupiter, which leads to the fact that the earth is rarely troubled by other planets and continues. In fact, the possibility of human extinction after being hit by an asteroid is very low. For more than two thousand years, the earth has been hit by twenty-six asteroids, causing no casualties, but it has also attracted people's attention.

First, there is no need to be afraid of asteroids. Although there is no preparation, there are corresponding technologies to deal with it now. And now we have more powerful technology, which can mine some minerals, protect the environment and improve mining efficiency to develop some minerals on asteroids. Some are relatively small, some can also cause extinction, but very few can also cause some destructive power, but there is no danger or threat to mankind. Monitoring data show that more than 10 asteroids have fallen in China in recent years. Asteroids are small in diameter and will not cause harm. According to statistics, asteroids with a diameter greater than 1km only hit the earth once every 1 10,000 years.

Second, there are many rare metals on these asteroids that cannot be found on earth. Obtaining resources from other planets is also the knowledge of many countries. At present, bio-mining technology has a good development prospect and has been applied to the mineral field. There have been plans to launch probes for many years, so the asteroid between Jupiter and Mars is called Lingshenxing. There are many resources on the spiritual star. As long as it is mined, if it can be mined, it will bring huge economic benefits. However, there are many difficulties in mining in space. It is still under study, hoping to overcome this difficulty and bring more resources.

Third, when it approaches in the same direction instead of coming head-on, the aircraft launched by human beings can't catch up with it in a short time. Therefore, humans can only find them early, launch the aircraft into outer space and wait, and then try to push it out of orbit. The farther this battlefield is from the earth, the safer human beings will be, so monitoring is the first.
