Will a mysterious asteroid that has been dormant at the edge of the Earth for 50 years pose a threat

The universe is in a changing combination of time and space. From the moment of birth hundreds of millions of years ago, although so much time has passed, some celestial bodies have fallen, as if they are dead planets, while others have just been born in the universe and are still in their youth. All of this can indicate that the planets in the universe are immature or ancient, and all these make up the universe.

First, however, according to previous news,Paul Jodas, an astronomer at NASA's Center for Near-Earth Object Research, has discovered an asteroid orbiting the Earth's periphery, and the asteroid is just a ghost. The results were unexpected, and thanks to the researchers' precise detection, they found that the asteroid had been orbiting the Earth's outer periphery for years before it was discovered by scientists. Of course, it's a good thing to find out now, but if you don't know what will happen when you find out later.

Second, the main reason for this is that scientists have been committed to the study of extraterrestrial planetsCompletely ignoring the conditions around the planet itself, and not even worrying at all. Asteroids are small in size, and when they appear outside the Earth, they need to be observed with very precise instruments. According to a foreign media astronomer on the official website, although the diameter of the asteroid is not a huge cosmic object, it is not a fuel-efficient lamp at all in this value range.

According to this logic, if it collides with the earth slightly, the result will be unimaginable.

3. Astronomer Jodas, however, has great respect for thisThink that humans don't have to be under too much pressure and don't have to worry about anything. As a result of a similar event a decade ago, there were also asteroids that hibernated on the Earth's periphery for a long time. He disappeared from the earth and has not returned yet, and has already infiltrated the universe.

So this asteroid is probably similar to this one, but it has been hibernating for decades before it begins to leave, and its impact on the Earth is simply ignored. Of course, in general, there are still various possibilities for this kind of speech on the earth, and they are all probabilistic events. Whether they can actually appear depends on the trajectory of the asteroid and cannot be determined by historical events.

It may be dangerous to the earth, and this asteroid may cause a devastating blow to the ecological environment and the entire earth in the future, and it may also have a very serious impact.

Such an asteroid, which has been lying in ambush around the Earth's periphery for 50 years without movement, is likely to be like a wild horse that has escaped in an instant, completely hitting the Earth, causing irreversible damage.

It may cause the destruction of the Earth's ozone layer, and it will also affect the Earth's rotation and revolution.

"Destroying the Gods". With a diameter of more than 400 meters, like the size of a small hill, this asteroid was only discovered in June 2004, and its orbit coincides with the Earth, often very close to the Earth, NASA scientists have calculated that it will be only 58,000 kilometers away from the Earth's surface on April 13, 2029, and if it passes through the gravitational "keyhole" with the Earth by then, then it will hit the Earth in 2036. In short, this is a very dangerous asteroid.

Naming

When the asteroid was discovered, it was tentatively numbered 2004 mn4, and when its orbit was determined, it was given 99942"This permanent designation (obtained on June 24, 2005) is also the only asteroid with a permanent designation that has a chance to hit Earth within a few decades. As of July 19, 2005, the object was named "Apophis", the Greek name for the ancient Egyptian god of darkness, chaos and destruction.

Apophis is also the main antagonist of the early sci-fi film Stargate: SG-1, in which he sent a fleet to attack Earth. But the protagonists eventually succeed in stopping him and blowing up his fleet.

The asteroid most threatening to Earth is named Bit (85713) 1988 SS49, and this asteroid is expected to converge several times in the future through the Earth's orbit, most likely closer than the Moon.

Scientists have observed an asteroid heading towards Earth, and the threat from this asteroid is small.

Here's the thing:Russia's Kerdesh Center for Mathematical Research posted a message on Instagram that an unidentified asteroid was heading for Earth. The message claims:

The Abbastu Astrophysical Observatory is currently observing an asteroid heading towards Earth at a distance of 8,400 meters. As soon as this news was issued, it caused a small wave on the Internet, and everything was dry. However, based on relevant observational data and related research, it can be concluded that the threat of this asteroid is not great.

The following is a detailed explanation of the orbits and sizes of the planets:

1. The asteroid's orbit does not coincide with the Earth, so it will not collideAccording to the relevant observation data, scientists analyzed: the orbit of this asteroid and the orbit of the earth have always maintained a Riemann chamfer angle greater than 20 degrees, which is a very safe chamfer range.

In this cutting angle, people may be able to observe the asteroid, but they will not hit the asteroid. At most, it's a passing by, so the asteroid is safe and there is no need to worry about it.

2. The planet has a diameter of less than 10 kilometers and is an asteroid, even if it collides, it can change its trajectory through external forcesAccording to observations, the asteroid is no more than 10 kilometers in diameter. Even if it crashes into the Earth, it can collide with an asteroid with a missile to blow up the trajectory of the asteroid.

Principle: First of all, this asteroid is relatively small. Secondly, when the asteroid approaches the Earth, it will have violent friction with the atmosphere, which greatly hinders the speed of the asteroid and slows down the asteroid's orbit.

As a result, you can launch a missile or rocket at an asteroid when it slows down, and according to the law of conservation of momentum, the smaller planet will deviate from its original orbit and move away from Earth.

Ivoropaev, chief engineer of the Institute of Mathematics of the Russian Academy of Sciences, said it was far enough away from the Earth so that it did not pose a threat. And this asteroid has already passed the Earth and has already flown far away.

The threat is particularly great, this lead hail is constantly being calculated and studied, and if Wang Jiliang accidentally hits the earth, it may have a serious hazard.

Asteroid impact on the earth is almost a daily occurrence, since ancient times, and it can be said that our earth itself is formed by asteroid impact, even now, there are several asteroids breaking into the earth's atmosphere every day, but the vast majority of asteroids are relatively small in size and mass, and when they enter the earth's atmosphere, they quickly rub off with the earth's atmosphere, and when it is hot, it usually emits strong light, which is the meteor phenomenon we usually see at night.

However, there are also some relatively large asteroids, such as asteroids with a diameter of more than one meter and less than ten meters, most of which do not rub away in the atmosphere, so they will fall to the ground to form meteorites after flashing a bright light in the sky. If the asteroid were any larger, it would cause catastrophic events near the place where it landed.

The asteroid that attacked the Chelyabinsk region of Russia, which once injured more than 1,200 people, and shattered all the glass in a radius of several kilometers near the landing site, Valery Shuvalov, a researcher at the Institute of Geosphere Dynamics of the Russian Academy of Sciences, said that the "guest (asteroid)" who visited the Chelyabinsk region can be a small meteorite one meter square and weighing several tons or even more than ten tons, it may be a very rare iron-nickel meteorite, this meteorite is very hard, because the celestial body needs enough hardness to reach the lower atmosphere, Otherwise, it will burn up and disintegrate in the atmosphere, and the meteorite will fall at a speed of about 30 kilometers per second, causing a strong shock wave, which will cause many injuries and destruction of the glass of the building, but fortunately the meteorite will eventually fall into Lake Chebalkuli, and if it hits the building, it will completely destroy the building.

A meteorite one meter square has such great power, a diameter of tens of meters, hundreds of meters is likely to bring disaster, usually the larger the volume of the meteorite, the more catastrophic it is, the diameter of more than 500 meters meteorite will bring global impact, a diameter of five kilometers meteorite will cause a global extinction event.

The asteroid that hit the earth 65 million years ago and caused the extinction of the dinosaurs, scientists speculate that it has a diameter of about eight kilometers, and is considered to be one of the major asteroid impact events in the history of life on the earth, and 80% of the earth's biological species disappeared in that impact.

So if such an arrogant asteroid hits the earth now, will we humans have a way to deal with it? Today, with the development of human science and technology, it can be said that we have initially possessed the ability to deal with asteroid impacts, and now all major aerospace countries have cosmic object monitoring systems, and there are some international astronomical organizations with this ability, and the orbits of many large asteroids have been preliminarily calculated, and the asteroids with the possibility of impact have been monitored, so we judge and respond to asteroid impacts in January or even months in advance, and then launch nuclear bombs on the surface of the asteroid to nuclear bombs** The reaction force forces the asteroid to change its orbit, so that the asteroid can avoid colliding with the earth, which is the initial ability of human science and technology to overcome natural disasters.
