What happens if an asteroid with a diameter of 1 km crashes into an aircraft carrier battle group?

Straight quiet 1km? I don't know if the landlord has seen "The Great Collision of Heaven and Earth", also translated as "Comet Hitting the Earth", the diameter of the asteroid that was blown out by the nuclear bomb seems to be about 1 kilometer, and the waves launched soaked the Statue of Liberty. The waves that high will directly push the battle group to the bottom of the sea.

Unless the battle group uses a bunch of anti-missile missiles with nuclear warheads (a few nuclear bombs are enough, and a bunch of them are launched to increase the hit rate, of course, to smash the planet into pieces, and the fragments will burn up when they enter the atmosphere, it will be possible to avoid total annihilation.

A kilometer? You have to look at how you land, you have to look at the angle of entry into the atmosphere. However, a kilometer is also a little bigger, and the anti-aircraft fire of the aircraft carrier is not against this, and it is useless at all.

1 km? Just kidding. Guided missiles are necessary. And interception needs to begin before entering the atmosphere. If you can hit the aircraft carrier group,. There were enough fragments for them to wipe out their entire army.

Absolutely.

It was wiped out before it entered the atmosphere.

If it weren't for the nuclear missiles, they would all be annihilated.

Missiles don't work.

How much energy will a spherical iron meteorite with a diameter of 100 meters hit the Earth in 100 kilometers per second?

Sphere volume formula: v=43r3

Kinetic energy formula: e=

So we can calculate:

Meteorite with a diameter of 100 meters: Joule.

Meteorite with a diameter of 1000 meters: Joule.

Meteorite with a diameter of 10,000 meters: joules.

For comparison: Hiroshima atomic bomb: Joule.

Tangshan**: Joule Joule.

Wenchuan**: Joule.

The most powerful hydrogen bomb ever made: Joule.

Tunguska Great**: Joules.

Sumatra big ** joules.

You can see that even if an asteroid with a diameter of only 100 meters hits the Earth, the result is catastrophic, and if an asteroid with a diameter of 10,000 meters hits, there is a historical precedent to investigate: the asteroid that caused the extinction of the dinosaurs was 9,600 meters in diameter, and its impact caused the liquefaction of the earth's surface within a diameter of at least 200 kilometers and the formation of a crater with a diameter of 180 kilometers, and the extinction of most of the world's life.

I roughly calculated that the kinetic energy equivalent is about 700 billion to 1 trillion tons of TNT equivalent. That's more than 100 times the world's current total nuclear yield.

So human civilization is directly reset. The sight is roughly equivalent to a world war.

However, it should not be enough to let the human race go extinct, and a small number of people will survive. Because the asteroid that wiped out the dinosaurs is estimated to be 10 kilometers in diameter and a thousand times heavier than yours.

If you want to have a good last piece of land, there are still a lot of architectural wreckage remaining.

Then the asteroid is about 50 kilometers in diameter.

In addition, kilometers are the same as kilometers, and 1 kilometer is 1 kilometer. 500 km is 500 km.

An asteroid with a diameter of 500 kilometers will smash the entire earth into pieces, and it will not retain any traces of human society.

It will knock the earth out of a big crater, and then tsunamis, **, volcanic eruptions, and so on will follow. The Earth's terrestrial atmosphere is forced to deteriorate! Animals and plants die, changing the original terrain and causing immeasurable disasters!

There are only two possibilities for an asteroid to hit the Earth during an approach to Earth: yes or no, and there is a question of chance. However, in reality, due to the accuracy of observation and complex gravitational perturbations, there will be a considerable degree of error in long-term forecasts, so only one probability can be obtained at present.

Although the probability of 1 in 10,000 is very small, the probability that it will not hit the earth is overwhelmingly advantageous after subsequent observations. However, before it can be completely ruled out, no matter how small the probability is, it needs to be taken into account. From my personal point of view, it doesn't seem to be of much significance to just talk about whether the probability is in danger or not, and it doesn't get to the point.

In the asteroid impact event that caused the extinction of the dinosaurs 65 million years ago, the asteroid was almost 10 kilometers in diameter. Scientists say the asteroid slammed vertically into the Yucatan Peninsula in Mexico at a speed of about 20 kilometers per second, which is 20 times faster than a high-speed bullet. The energy generated by the impact was 1 billion times higher than the energy of the atomic bomb dropped by the United States on Hiroshima, Japan, during World War II.

The atomic bomb on Hiroshima, Japan, is equivalent to the energy released by 20,000 tons of TNT explosives. Then an asteroid with a diameter of 10 kilometers hits the earth, and the energy released is equivalent to the energy released by 20 trillion tons of TNT explosives at the same time. The asteroid impact 65 million years ago produced a huge shock wave and heat wave, causing fires and a magnitude of more than 10 on the Richter scale**, causing the continental plate to move and form a tsunami up to 300 meters high.

At the same time, the impact ruptured the Earth's crust and ejected between 100 billion and 500 billion tons of sulfuric acid and dust into the atmosphere from the Earth's interior. These materials have blocked out sunlight, triggered global acid rain, sent the Earth into a cold ice age, and severely damaged ecosystems in both the sea and land, leaving nearly half of the planet's species unable to adapt to this hellish environment and going extinct, including the dinosaurs that ruled the planet for hundreds of millions of years.

It is understood that in recent years, the United States, Britain, France, Germany, Japan, Russia and other countries have jointly established an international monitoring network for near-Earth objects, and more than 1,640 potentially threatening near-Earth asteroids have been discovered. Among them, astronomers are most concerned about a near-Earth asteroid called "Apophis". According to the American "Discovery Channel"** report:

In 2004, scientists discovered that the asteroid Apophis was a threat to Earth, and that it was large enough to wipe out life on Earth. The Apophis asteroid was discovered in 2012 and is more than two football fields wide and 400 meters wide. 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 thought that if"Apophis"An asteroid impact on Earth will not cause global destruction, but it may cause a serious regional catastrophe. The United Nations Committee on the Peaceful Uses of Outer Space (COSP) convenes an annual meeting of the Scientific and Technical Group, which includes a special discussion on the topic of NEOs, summarizes the observation and early warning of NEOs in the current year, and guides follow-up observation and research plans. As a representative of China's NEO researchers, Zhao Haibin, chief researcher of the NEO Telescope Group of the Purple Mountain Observatory, has been invited to participate in the conference for three consecutive years.

Humanity's ability to protect against asteroids is improving. Zhao Haibin said that on the basis of monitoring potential threat asteroids and effectively calculating their orbits, once an asteroid or comet with a serious threat to the earth is found, a rocket or spacecraft carrying a device can be launched to detonate near the asteroid to change its speed and direction, so as to ensure the safety of the earth.

Not too! It takes at least a meteorite with a diameter of 100 meters to crash into the earth to touch the surface of the earth! The thickness of the earth's atmosphere is five or six hundred kilometers thick, and then it rushes into the atmosphere at the speed of hundreds of kilometers per second of meteorites, and the drag and friction are particularly large, and it is worn away by the atmosphere after a while; A meteorite of this size would have been treated as a meteor at night!

The power of an asteroid depends not only on its mass, but also on how fast it flies towards Earth. Generally, a meteorite of 200,000 kilometers per hour will destroy the earth (if it completely destroys life), and the diameter is between one kilometer and two kilometers. However, scientists will not let the asteroid collide, so there is no need to worry about ......

It depends on the angle, shape and composition of the orbit, as well as the speed, so it is impossible to give an accurate answer to the impact of a celestial body with a diameter of a kilometer, just like a leaf, a tornado wrapped in leaves can penetrate the human body, but at the same time it is related to the angle of force.

Tunguska** (caused by an asteroid with a diameter of 60m "kissing" Siberia) Ending: (I don't remember enough).

1. People who are 30km away from the center of ** are thrown into the sky.

2. The clothes on the drying rack 70km away from the center of ** are scorched (I forgot a few).

3. The luggage of the train 1000km away from the center of ** was shaken off the shelves 4. Almost all the aurora can be seen in the northern hemisphere.

5. ** waves were recorded around the world.

6. Economic loss? More than 100 million (I can't remember exactly).

7. If the meteorite falls a few hours late, it will hit Europe (the earth is rotating), it is estimated that the earth's atmosphere can only withstand an asteroid with a diameter of 50m, and an asteroid with a diameter of 1km is enough to bring a global disaster.

By the Way: The asteroid that caused the extinction of the dinosaurs was ten kilometers in diameter.
