If an asteroid hits Earth, what do we do about it?

Asteroids have different diameters, impact speeds, impact angles, and impact locations, resulting in different destructive effects on the Earth.

If you don't have to, don't you think it's too late to take action after the asteroid hits the Earth?

However, the Earth has a very thick atmosphere, so there is a probability of collision with alien stars, and the probability of collision with a star with a larger diameter is smaller.

Generally speaking, for the earth, about 10 stars with a diameter of about 10 meters rush into the earth's atmosphere every year, and about one or two will fall to the ground to form meteorites or meteorites, which will not cause any serious disasters.

Stars with a diameter of about 50 to 100 meters will rush into the earth's atmosphere every 100 years, and some will fall to the ground, causing a limited range of disasters.

A star with a diameter of 1,000 meters, about 100,000 years, will rush into the Earth's atmosphere and hit the ground, which will cause a global catastrophe (one of the reasons why scientists speculate that the extinction of dinosaurs), unless you are not on Earth at this time, you are estimated to die.

Therefore, in fact, the best way is to scientifically observe asteroids, detect stars that may collide with the Earth in time, and scientifically determine the diameter of the asteroid, its velocity, the possible impact angle, the impact location, and the destructive force that the impact may cause to the Earth.

Then take measures - such as launch a deep impact or something, blow up the star or change its orbit to keep it away from the Earth.

It can only be said that it lies in the true size of the planet, and a little smaller may be the affected area, but it also needs to face the reality, and it can't be pushed like the wandering earth.

I don't think we can do anything about it, because human beings are weak in the face of nature.

There is little to deal with, because humans are helpless against nature.

The answer is that there is no measure, the trajectory of the earth is almost fixed, unless the earth itself can feel it, but this is pure fantasy.

The asteroid hit the Earth should be ** early to hit the Earth and destroy it too late.

Nothing can be done to survive, and you may only be able to prepare a good-looking posture and wait for death.

The asteroid hits the Earth long in advance** It's too late for the asteroid to destroy the Earth.

Human scientists must have a way to deal with it, rest assured.

We can launch a spaceship to destroy an asteroid.

There is no measure, after all, the power of nature is infinite, and man cannot overcome the sky.

Scientists have long had such considerations, scattering with missiles.

There's nothing that can be done about it, because humans are so small.

The means of human defense is that it can be defended by satellites, it can be defended by armed forces, it can be defended by the atmosphere, it can be defended by missiles, and it can be defended by cruising technology.

Human beings can develop a satellite rocket, which can be used to prevent the asteroid from hitting the earth and change its trajectory, so that the planet will not directly hit the earth, which can protect mankind.

The most feasible defense method for mankind is to carry out nuclear explosion, which is the simplest, crudest and most effective.

Humans may not have any means of defense, and humans will probably use technology to defend themselves, which is generally insignificant.

If an asteroid hits the Earth, I think it can be dealt with with the current technology of human beings, but it will be very damaging.

The asteroid hitting the earth is unstoppable with current human technology, because when the asteroid enters the earth from outer space, the inertia of the asteroid will increase and the kinetic energy will increase through gravitational acceleration.

With our current technology, we can't stop an asteroid from hitting the Earth, because our technology is mainly aimed at human life.

I think we can cope with it, because the technology is very advanced now.

With the current technology of mankind, if the asteroid can be detected in time to be in the orbit of the impact on the earth, and there is enough buffer time, the danger can be dealt with. However, the problem is that with the current human technology, it is not possible to completely monitor whether there are asteroids to hit the earth, especially some smaller ones, which cannot be successfully monitored and perceived.

The Earth itself is protected by an atmosphereAn asteroid is a small stone floating in the solar system, or it may be iron or other minerals, attracted by the gravitational pull of the earth in the process of flying, and then fly to the earth, although there are countless asteroids around the earth, there are many asteroids flying to the earth every year, but they do not threaten the safety of the earth, because the earth has an atmosphere as protection, the asteroid will rub against the atmosphere when it enters the earth's atmosphere, and the high-speed friction will produce a lot of heat energy. This heat energy will melt the asteroids, so that the asteroids disappear in the air, and some large asteroids will be broken down into sizes that are not harmful to the Earth. <>

The Moon has blocked meteorites for the EarthWhen the earth is facing the attack of asteroids, it not only has the protection of its own atmosphere, but also has a vital layer of protection in space, that is, the earth's satellite, the moon in front of the void. The Huiran Moon also has a gravitational pull, although it is not as big as the Earth, but it can also capture asteroids and attract the asteroids that originally flew to the Earth to the Moon, which can be confirmed from the countless craters on the Moon, so the Earth has not been attacked by huge asteroids until now, all because the Moon has helped the Earth withstand these impacts and protect the Earth. <>

Humans can also destroy asteroidsThe earth not only has natural protection measures, but also the ** of human civilization can also destroy some asteroids. For example, the asteroid defense system that all countries are forming now is an organization established for the harm of asteroids, when it is found that the asteroid will hit the earth and the atmosphere cannot decompose the asteroid, it will launch missiles to destroy the asteroid, even if it cannot be destroyed, the asteroid can be decomposed, such as minimizing the harm of the asteroid to the earth, but the asteroid is too large for human beings to deal with, but with the rapid development of human science and technology, I believe that in the near future asteroids will no longer be a threat to Earth. <>

There is a lot of gravity, and there are many large planets next to the Earth, which are easy to dodge.

There are other planets and moons to protect, such as Jupiter and the Moon, which can protect the Earth.

If you want to avoid the impact of their stools, you must let them maintain a certain trajectory and running rules, and let Zao Min observe them to do their own work in their own position.
