What are the chances that a pyramid sized asteroid could hit Earth in 2022?

Because the Earth is in a space environment, and there are many small celestial bodies in space, they are roaming in space, some of them have relatively stable orbits, and some of them are uncertain, because of the complex gravitational interaction, they may pose a threat to the Earth. Therefore, astronomers have been keeping a close eye on the movements of extraterrestrial objects, knowing their orbits or periods in case they happen.

With the improvement of human observation, astronomers have discovered that there are many small celestial bodies around the Earth, which periodically visit the vicinity of the Earth and pass by the Earth. NASA announced that an asteroid about 128 meters long and the size of the Pyramids of Giza could collide with Earth on May 6, 2022.

Asteroid impact.

What would be the harm if this asteroid hit Earth?

The 128-meter-long asteroid is no slouch, and if it hits the Earth, it will release about 230,000 tons of TNT explosives**, which is 15 times more powerful than the Hiroshima atomic bomb.

Fortunately, the probability of impact is extremely low, only the probability of not higher than that, it can almost be considered impossible, but since there is a potential possibility, so in the next two years, the astronomical observatory will always pay attention to its movements, delineate its trajectory, and take timely measures.

Asteroid impact.

Judging from the current level of human science and technology, it has the ability to deal with the impact of these small celestial bodies, such as this 128-meter celestial body, it is not too big, if it is attacked by nuclear bombs, it can be broken into multiple fragments, which can effectively use the atmosphere to burn it out, even if some fragments hit the ground, it is only some smaller fragments.

Of course, if the expected impact site of this asteroid is the ocean, then there is no need to take any measures, it may disintegrate in the atmosphere, and after the baptism of the atmosphere, it will definitely decrease in size, and then crash into the ocean, as long as the impact site is not close to some coastal cities, then there is nothing to worry about.

Asteroid impact.

As far back as 65 million years ago, an asteroid with a diameter of about 10 kilometers hit the Earth, causing the extinction of the dinosaurs, covering the Earth's surface in a thick cloud of dust for several years, and almost all the animals and plants on land died. However, the probability of a 10-kilometer-sized object hitting the Earth is even lower, not once in hundreds of millions of years. The speed of human civilization is extremely fast, and it may not be long before human beings will advance to an interstellar civilization, and there will be no need to be afraid at that time.

An asteroid the size of a pyramid may hit the Earth in 2022, which is more probable, but it is more harmful, because if the asteroid really hits the Earth, the consequences are really unimaginable.

In the vast earth, the volume of the earth seems very small, but even if it is so small, it is still possible to hit the earth, but this possibility is very low, because if there is really a high probability, the corresponding national agencies have reminded people to take corresponding precautions.

With the development of science and technology, if an asteroid is about to hit the earth, people will also take some necessary measures to effectively avoid it.

In fact, there are many small celestial bodies around the earth in 199, which periodically visit the vicinity of the earth and pass by the earth. If you're not careful, you'll have an intimate encounter with the earth.

It feels like the likelihood of this impact is not too great, in terms of modern civilization. If there is an impact, it can be reached at the moment, then there is no such possibility, otherwise it will be particularly terrifying.

According to US media, an asteroid the size of the Pyramid of Khufu passed by the Earth on July 24. Experts say there is no need to worry.

According to Fun Science on July 24, you hardly need to worry about an asteroid you've heard is heading for Earth. This is mainly due to the fact that large asteroids can fly by the Earth at any time without causing any accidents – including asteroids much larger than this one. To hit our tiny planet, these space rocks must be precisely targeted.

Even if they do enter our atmosphere, most of them are not large enough to cause significant damage. As for the rare asteroids that could theoretically cause damage, most of them do not fall near population centers.

Another reason not to worry: If you hear about an asteroid on the news before it approaches Earth, it means that NASA has long since spotted it and accurately tracked its whereabouts in space. NEOs found and tracked by NASA like this are not a cause for concern;NASA's Planetary Defense Coordination Office has been keeping an eye on them and will be years ahead of how close they will be to Earth.

The real danger, albeit small, comes from the large number of small to medium-sized asteroids that NASA's radar cannot detect. Theoretically, they could fall from the sky at any time, but the chances of this happening are very, very low, and the likelihood of threatening your life is even lower.

However, as Emily Kramer, an astronomer at the Jet Propulsion Laboratory, said in an interview, while 90% of NEOs larger than 1 kilometer in diameter have been discovered, only a small fraction of the smaller NEOs (between 140 meters and 1 kilometer in diameter) have been spotted. These medium-sized space rocks pose a small but real threat to human life in the short term, and because of this, NASA's Office of Planetary Defense Coordination is working hard to find and track them.

This time, the asteroid, named 2019 OD, is between 51 and 110 meters in diameter. Its distance from the earth will not be less than 10,000 kilometers. You can't even see it with a telescope.

It's not that rare either. So, no matter what the tabloids say, don't worry.

It's hard to say.

In the early days of the formation of the solar system, events of asteroids (or other types of small bodies) hitting Earth were frequent. As the inner solar system is gradually "emptied", such impacts occur less and less frequently.

Scientists estimate that the probability of an asteroid with a diameter of about 1 kilometer colliding with Earth is once every 600,000 years. An impact on an asteroid with a diameter of less than 1 kilometer and more than 100 meters may occur once every 10,000 years. For example, an asteroid about 10 kilometers that caused the extinction of the dinosaurs 65 million years ago hit the earth, and it only happens once in tens of millions of years.

At present, NASA has only calculated the orbital parameters of the asteroid numbered JF1 based on the current monitoring data, and believes that there is a possibility of hitting the earth in 2022, and if it hits the earth, it will release about 230,000 tons of equivalent energy, which is not enough to catch up with some nuclear tests conducted by humans.

The probability that the pyramid size asteroid will hit the earth in 2022 is only 1 in 10,000, and the probability of most asteroids hitting the earth is a few in 10,000, so this probability is very high.

NASA said a few days ago that an asteroid could hit the Earth, but in fact, the probability of its impact is very small, that is, 1 3800, which is almost impossible.

This probability is not even 1%, because the uncertainty of the universe is too great, and the chance of these two objects meeting is not very high.

According to NASA exploration reports, the probability that the pyramid size asteroid will hit the Earth in 2022 is about right。It is said that when NASA detected the trajectory of this asteroid, it speculated based on its speed and direction, and this speculation shocked the whole world at the time, and it is said that if the asteroid hits successfully, it may have a devastating effect, and it can blow up a city that can accommodate millions of people in an instant.

And this asteroid was discovered by NASA in November 19, and we all know that the United States' aerial detection technology is very powerful. And after the discovery of the asteroid, they conducted a study of the asteroid, and the results of the study showed how harmful the planet could be. It is said that someone made a rough summary of the damage caused by the impact of the planet on the earth much earlier, and it was this piece of information that allowed researchers at the time to calculate the possible damage caused by the pyramid-sized planet.

It's 2020 now, and it's only two years away from this ** time. The trajectory of this asteroid is also closely watched, but everyone does not need to be too alarmed, after all, the probability of hitting the earth that has been shown by research is basically negligible。In other words, the likelihood of him hitting the Earth is as small as if you were going out in the morning without pants.

But we all know that we are born in sorrow and die in peace, so we all know that this matter is about one thing, and what should come will always come, and what should not come will always not appear. As long as we do a good job at that time, after all, only time is the best proof of the future, so we can also keep an attitude of concern about whether this pyramid-sized asteroid will hit the earth.

The probability of an asteroid hitting the Earth is 27, and its diameter is so small that it will be destroyed before it gets close to the atmosphere and will not cause any damage to the Earth.

NASA, as the national astronomical agency of the United States, has received relatively little funding every year since the end of the Cold War between the United States and the Soviet Union, so he will make these assumptions, mostly to get money from the United States Congress.

Through the research of scientists, it will not crash into the earth, because its trajectory coincides with the trajectory of the earth, so when the earth revolves around the sun, it can just avoid the impact of the planets.
