Will Afipos really hit the Earth 5

Possibly, but the probability is extremely small, only 1 in a few hundred thousand. Moreover, the answer to this question is almost impossible to be conclusive before 2029.

How to say,** often use the title to attract attention, "Asteroid Apophis 2036 or impact the Earth", this "or" word is very wonderful, it does not change the willingness, but it changes the reading perception, compared to "Scientists say that the asteroid Apophis has a 1 in 330,000 probability of hitting the Earth" has a lot of impact, right?

However, the facts do not change with the change of description, if the mouth cannon is useful, it is time to let the ** detect the early warning instead of playing with right and wrong, right? So what is the orbit of this asteroid? It will approach the Earth again in 2029 (about 2 million kilometers will never hit), and this time it will approach the asteroid's orbit, and it is unknown whether it will impact in 2036.

No matter how you understand it, any observation will have errors, and it is easy to understand. However, in the process of setting Apophis's orbit, the error is magnified twice, one of which is that the current observation error will affect the position of the Earth in 2029. What's more, after approaching the Earth in 2029, the orbit will be corrected, and a small change in the motion parameters at that time will be magnified in 2036.

This is the conclusion at the beginning, and now for the error of two amplifications, we can only do a probabilistic statistic, and try to correct it through the accumulation of observation data. However, before 2029, such work will not make much sense.

Actually, for astronomers, it's not a big deal, after 2029, and if it can be installed, it will be really a five-digit luck in the lottery, and the current technology can already intervene in the orbit of the asteroid and give a small momentum. However, for the public, it is not easy to be fooled. Actually, Apophis should be the happiest about this, right?

What was originally an obscure big stone turned out to be hot. Last year, a probe came to Vesta, but little is known, I wonder if it will feel the heat and coldness of the world.

Yes, **conspiracy. No, long live science.

Apophis does not hit the Earth. According to the latest observation report in 2013, Apophis will not hit the Earth in 2036, in fact, as early as December 28, 2004, it was calculated that Apophis will have a high probability of 1 450 hitting the Earth, that is, only 58,000 kilometers from the Earth's surface, which is lower than the altitude of most artificial satellites, mainly because its orbit and the Earth's orbit have intersected.

The intersection of Apophis and the EarthAlthough Apophis will be able to pass by the Earth at an extremely close distance in 2029, scientists believe that Apophis is likely attracted by the Earth's gravity, causing his orbit to become bent, which could lead to a collision with the Earth at a location in April 2036. But later, scientists made precise calculations to determine Apophis' orbit, thus narrowing the probability of Apophis hitting the Earth in 2036 to one in a million.

Apophis does not hit the Earth. Apophis, or Annihilation, is an asteroid that orbits the Sun and orbits the Earth about once every seven years. Its orbit crosses the Earth's orbit, causing a disturbance so that it may crash into the Earth.

However, according to the January 2013 observation report, the full possibility of the destruction of God hitting the Earth in 2036 has been ruled out.

Nearly 200 initial observations (from June 19, 2004 to December 27, 2004) indicate that Apophis reached its closest position to the Earth's eastern hemisphere at 4:49 GMT+8 on April 14, 2029.

The probability of colliding with the Earth at around 5:20 GMT+8 on the same day is 1 37 (.

In the event of an impact, 6,400 trillion kilojoules of energy will be released, which is equivalent to the energy released by trillions of kilograms (100 million tons) of TNT explosives**.

Apophis does not hit the Earth. Apophis, also known as Anniversary, is a near-Earth asteroid that orbits near Earth about once every 7 years. In 2011, Donald Yomans, head of NASA's Office of the Near-Earth Object Program, in an interview with **, proposed preventive countermeasures against the threat of Apophis, saying that if the probability of a collision is very high, the space agency also has a way to push the asteroid away from the orbit where it collided with the Earth, and the simpler way is to launch a spacecraft to hit the asteroid into an orbit far from the Earth.

No.

Davide Farnokia, a scientist in the field of near-Earth objects at NASA, said in a research report published on the 26th: "The possibility of an impact in 2068 no longer exists, and our calculations do not show any impact risk for at least the next 100 years." ”

Discovered in 2004, the asteroid is about 340 meters long and named after Apophis, the ancient Egyptian god of chaos and darkness. Scientists previously thought it could hit the Earth in 2068 based on its orbit around the Sun.

Apophis "flies over the Earth, about 17 million kilometers above the surface. Using radar observations, astronomers adjusted their estimates of Apophis' orbit to rule out the risk of the asteroid hitting Earth in 2068 and beyond.

Consequences of planets hitting Earth:

An asteroid with a diameter of 1 km hitting the Earth at a speed of 25 to 30 km per second would have a devastating effect. During the impact, the enormous kinetic energy of the celestial body is instantly released into the target rock, with an equivalent of 300,000 tons of TNT – the largest man-made nucleus has an equivalent of 600,000 tons.

The lightning and shock waves from the impact can destroy an area the size of Belgium. Within seconds, a 20-kilometer-wide crater will form, and the resulting debris will be ejected into the Earth's suborbit, which will then re-enter the atmosphere, like a large meteor shower that spreads across the globe, forming a strong global heat pulse that will cause fires and destroy large amounts of biomass.

The ozone layer will disappear. A large number of volcanoes and ** will occur throughout the planet with shock waves. When the impactor enters the atmosphere, the intense acid rain from the collapse of oranges due to the ionization of the air, and the large amounts of pyrotoxins from the global fires will fall on a global scale.

In addition to these effects, impacts, once impacted in an offshore area, can produce huge tsunamis, which can travel considerable distances and are accompanied by enormous energy.

These waves will pose a significant threat to low-lying coastal areas. An asteroid with a diameter of 1 km impacts the Atlantic Ocean and produces deep-water waves 10 to 15 meters high. When an asteroid hits the continental shelves of Europe and North America at a speed of 600 kilometers per hour, the wave height formed will be between 300 and 800 meters, depending on the coastal topography.

Apophis is an asteroid with a diameter of about 370 meters, which has caused concern because of its proximity to Earth. But judging by current scientific research and observations, Apophis will not hit China or any particular country in the coming decades.

Apophis is a near-Earth object whose orbit is so close to the Earth's orbit that it has raised concerns about its possible impact on the Earth. However, scientists have made detailed calculations and observations of its trajectory, and ruled out the possibility that it could hit the Earth in the short term. According to current observations, Apophis is closest to Earth at about 16 million kilometers, far exceeding the distance between the Moon and Earth.

Based on this, Apophis will not hit China or any particular country in the next ten years, so you can rest assured.

In addition, scientists are keeping a close eye on the trajectory of Apophis so that they can take timely action if any anomalies are detected. They have developed a series of technologies and tools to monitor celestial objects, such as telescopes and satellite monitoring, which can continuously observe and analyze the trajectory of Apophis. With the continuous development of science and technology, we have reason to believe that technologies such as monitoring and analysis of celestial bodies will become more sophisticated and advanced, so as to better protect the earth and human beings.

In summary, Apophis will not hit China, and scientists have studied and observed its trajectory in detail and are paying close attention to its trajectory. We should be confident that the development of science and technology and the efforts of scientists will better protect the earth and people. <>

Not necessarily, after all, it was a long time later.

But I can give you some information about Apophis.

The asteroid Apophis hits the Earth, an asteroid 400 meters wide, and the latest calculations and recent data indicate that the probability of Apophis hitting the Earth on April 13, 2036 has dropped from 1 in 45,000 to about 4 in 1 million, and on April 13, 2029, it is 18,300 miles (about 29,450 kilometers) above the Earth's surface, thus setting a record for the closest thing to Earth, which is of course harmless to Earth.

Monica Grady, an expert on meteorites at the Open University in the United Kingdom, said: "It is only a matter of time before a near-Earth asteroid collides with the Earth, not if. Many of the smaller space objects melted as they crashed into the Earth's atmosphere, so they failed to collide with the Earth.

However, an asteroid with a diameter of more than 1 km will collide with the Earth every hundreds of thousands of years, and an asteroid with a diameter of more than 6 km will collide with the Earth every hundreds of millions of years, and such an impact would trigger an extinction catastrophe. This time, humanity is facing a big guy who is late. ”

It has attracted the attention of scientists in recent years due to the possibility of impacting the Earth in the relatively recent future. Scientists once believed that if the Apophis asteroid hit the Earth, it would not cause global destruction, but could cause a serious regional disaster.

Apophis is believed to have a chance to hit the Earth in 2029. NASA scientists have found that "Apophis" will pass by the Earth in 2029, but will return to the Earth in 2036 and may break through the atmosphere and collide with the Earth! Apophis is currently ranked at Tier 4 of the Torino Scale, and a Grade 10 means an inevitable global devastating collision.

Apophis has the highest danger rating of any asteroid ever discovered, and scientists once thought it had a 1 in 37 chance of colliding with Earth in 2036!

Judging by these sources, Apophis may rub against the Earth's atmosphere, but not to the point of destroying the Earth!

Don't be afraid, scientists across the country say that after the asteroid appears in 2029, each country will launch one or two nuclear bombs, because scientists have already imitated it and it can indeed be used.

First of all, this asteroid is real, number 99942, and the English name is Apophis. In Egyptian mythology, apophis is the god of destruction and darkness, so its official Chinese name is translated as "Destruction Star". It is a near-Earth asteroid with a diameter of about 270 meters, and if it hits the Earth, it will release 25,000 times more energy than the Hiroshima atomic bomb.

When it was first discovered in 2004, due to the lack of observational data, there was still a large uncertainty in the calculation of the exact orbit of this asteroid, so at that time, the probability of it hitting the Earth in 2029 reached the highest, which was the highest risk of hitting the Earth on record. But subsequent observations have completely ruled out the possibility of a "Destroyer" hitting the Earth in 2029.

On April 13, 2029, which happens to be Black Friday, the asteroid will pass by Earth at least 29,470 kilometers away – a distance lower than the altitude of a geostationary satellite. An asteroid of this size grazing the Earth so close is statistically speaking, on average, only once every 800 years. At that time, the asteroid will be visible to the naked eye.

However, after a close flyby of Earth in 2029, Annistar will be affected by Earth's gravity and turn into another orbit. Current estimates suggest that the asteroid may orbit back to Earth again on April 13, 2036. Since the asteroid's orbit is still affected by some uncertainties, such as the interference of the Yarkovsky effect, it is currently impossible to determine the orbit of Anglomer in 2036.

As of October 7, 2009, the probability of astronomers** destroying God hitting Earth on April 13, 2036 is about 1,250,000.

But in 2013, astronomers had a good chance to revise the orbit of Reposacher with precision again. On January 9, the planet will pass by 14.45 million kilometers from Earth. Although the distance is still quite high, radars on the ground are already able to observe it and accurately measure its distance.

The observation is expected to dramatically improve the accuracy of the asteroid's orbit, with a high probability of completely ruling out the possibility of its impact on Earth in 2036.

At the very least, on NASA's Jet Propulsion Laboratory (JPL) official page, astronomers are quite optimistic that upcoming observations are likely to confirm that on April 13, 2036, the planet will be 49 million kilometers away from Earth.
