    We know that in the huge universe, there are many planetary celestial bodies, and these planetary celestial bodies have their own orbits, or they become garbage in the universe without their own purpose, and they fly in the universe ethereally, which is also a very normal phenomenon in the entire universe. And these meteorites or asteroids, which have no purpose and are not attracted to other planets, will land on this planet when they are attracted to one planet. So about asteroids being a threat to Earth?

    What are the scientific reasons for this? Asteroids are definitely a threat to Earth, and the main reasons for this are as follows. <>

    1. Change the earth's climate and environment. First of all, the first point is that if an asteroid hits the earth, it will definitely change the condition of some of the natural climate of our earth. Because the asteroid is very huge, and this huge asteroid will cooperate with our air and various factors in the process of landing, generating a lot of friction and heating, if it lands on the earth, it may form a fireball.

    And if such a fireball hits our ground, it is likely to change the ecological environment and climate of this continent or an island. If this is the case, our precedent dinosaurs were very good at encountering such a situation, encountering an asteroid impact that directly triggered a volcanic eruption in the Earth's interior. <>

    Second, there is the possibility of a tsunami. Secondly, the second point is that there is also the possibility of a tsunami, and if the asteroid hits our oceans, such as the Pacific Ocean, it is very likely that the surrounding coastal countries will face a serious tsunami problem. Because, the water in the sea was suddenly hit by a huge asteroid, and the impact caused by this planet was very huge, which would stir up thousands of layers of seawater.

    Tsunamis are also inevitable. <>

    Third, there is also the possibility of volcanic eruptions. Finally, we know that there is a geological structure in the interior of the earth that is very unstable, and there are countries in the interior of the earth, such as Malaysia or Southeast Asia, and if a meteorite falls on these areas, it is very likely to cause a volcanic eruption.

    There is danger, and it will even pose a serious threat to the Earth, because the asteroid may fall, and when he falls, it may hit the Earth, and at his speed, it may even cause a devastating blow to the Earth.

    At present, asteroids do not pose a great threat to the Earth, of course, it is not excluded that there is a possibility that the asteroid will change its orbit to other places, or threaten the Earth, such as the possibility of **, collision, etc.

    Asteroids are still not much of a threat to the Earth, because the Earth's periphery is protected by the Moon in orbit, so the asteroid cannot hit the Earth.

    These asteroids have the potential to pose a threat to Earth in the future.

    Asteroid impact on Earth is a very common phenomenon. Scientists have found that there are many asteroids in the solar system that have extremely strong gravitational pull, volume and density, and the larger the diameter, the larger the volume. The more likely they are to hit the Earth.

    Theoretically, some asteroids or comets in the solar system would produce ** when they collide with Earth.

    Scientists have discovered 3 asteroids that may threaten Earth.

    On November 1, 2022, an international team of astronomers discovered three near-Earth asteroids hidden in the Sun's bright light, one of which is a "planet killer" that could pose a threat to Earth in the future. After the incident, it attracted the attention of many netizens on the Internet, and it is reported that relevant personnel have tried to protect the earth by changing the orbit of the asteroid and have succeeded.

    If it hits the Earth, what will it do to the Earth?

    If this asteroid hits Earth, it will burn up in the atmosphere and produce a lot of energy, which will then release a lot of hydrogen. This could be devastating to the Earth's atmosphere, while also altering the structure of the atmosphere. Under the action of hydrogen and helium, it forms a large fireball that flies over the surface of the planet.

    When an asteroid collides with the Earth, the asteroid hits rocks, trees, and atmospheric barriers on the ground. These collisions all generate heat and alter the surface temperature of the asteroid. Eventually, hot lava and lava may be produced on the surface, creating a large lava pit made up of rock and water.

    The water in this lava pit will form steam.

    What are the possibilities?

    For asteroids, the most terrible threat comes from asteroid bodies. For Earth, if an asteroid hits, it will have a very serious impact on Earth. There are two scenarios in which an asteroid hits the Earth, namely an "impact" and an "erasure" impact.

    An "impact" is the process by which an asteroid is affected by the Earth's gravitational pull as it passes near the Earth and changes its direction or orbit on the Earth's surface. In this process, the asteroid changes direction or speed under intense pressure from the Earth, making some parts of the Earth outside of the cliff areas.

    There is a high probability that these asteroids will hit the Earth, and according to scientists, one of them may pose a threat to the Earth.

    There is no such possibility, because the asteroid is still far away from the Earth, and it is impossible for an impact to occur.

    "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.

    Do scientists say an asteroid is approaching and poses a threat to Earth? The asteroid impact on the earth happens every day, and the meteor phenomenon we see at night is actually the luminescence phenomenon produced by frictional ablation after the asteroid breaks into the earth's atmosphere, and some fire meteor events are caused by the asteroid not completely ablating off after entering the atmosphere, so as to fall to the earth, so the asteroid will form a meteorite on the ground. On a million-year scale, the probability of an asteroid hitting Earth is 100%.

    This is the data given by astrophysicist Doshi Calais. On a scale of 100 million years, Neil Douglas Tyson gives data that most of those asteroids with a diameter greater than 1,000 meters will crash into the Earth within 100 million years. In the solar system where the Earth is located, there may be 1,000-1,500 asteroids with diameters greater than 1,000 meters, and nearly a million asteroids with diameters greater than 50 meters.

    They are distributed in the asteroid belt between Mars and Jupiter, and their elliptical orbits intersect with the Earth's orbit. According to convention, these asteroids will be named after people or places, and the asteroids named after the Chinese are Zu Chong's Star, Zhang Heng Star, andQian Xuesenxing and so on as many as 120.

    Let's hope they don't rush to Earth. Astronomers have been keeping an eye on these dangerous little guys, and fortunately, only 42 asteroids have been found to hit the Earth at a certain time. They will often give some warnings, causing many false alarms.

    Computers calculate that an asteroid called 1950da could hit the Earth on March 16, 2880, and although the probability is not very high, it is not zero. Judging from the current speed of scientific and technological development of human beings, it will not take too long to have the ability to avoid disasters, so there is no need to worry, maybe it will be a surprise. In fact, it is very common for asteroids to hit the Earth.

    But devastating giant asteroids are rare, and if there is nothing to interfere with the impact on the earth, it is actually a matter of probability, but don't worry, they will solve it, and if they can't solve it, then there is no way.

    It is possible to pose a threat to the Earth, but this is also a matter of probability, it is possible that the asteroid will ** itself during the approaching process, or it may cause some damage, but it will take time to verify.

    Humans can use spacecraft for defense. It is difficult to destroy an asteroid by using a spacecraft to hit it, but it can change the orbit of the asteroid, because the impact will cause the orbit to deviate, and it will affect the speed of the asteroid, thus indirectly changing the orbit of the asteroid and avoiding collision with the Earth.

    It is necessary to monitor in advance, use existing instruments to carry out the trajectory of the asteroid, and then intervene to avoid being impacted.

    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.
