Is it possible for a comet to collide with Earth?

Yes. There are probably thousands of asteroids orbiting and intersecting the Earth, which means that thousands of asteroids can collide with the Earth. However, the odds are slim and old.

However, in recent decades, several asteroids have had a chance to approach Earth, and it is unknown whether they will collide (without the case of special envoys, they should not collide). At least for the rest of your lifetime, we don't have to worry about a comet colliding with Earth.

In this life, if you are really lucky enough to see a comet destroy the earth! My greatest wish is to be able to witness this great astronomical spectacle from the best vantage point! Even for a moment, at that moment, the spirit of the entire human race will be sublimated.

It turns out that death can be like that. He will be better than any death in the history of mankind! As far as I'm concerned, if I can see such a scene, why die?

Comets have the potential to hit the Earth, and comets are divided into three parts: the nucleus, the coma, and the tail, which is composed of very thin gas. So, the Earth will not be affected when it passes through the comet's tail, but it will not be so safe if the comet's nucleus, a major part of the comet, hits the Earth.

When it comes to comets, many people think of comets as beautiful celestial bodies with long tails. And in ancient times, the appearance of comets was often seen as a sign of disaster. In fact, it is just a natural phenomenon.

The comet we see is made up of three parts: the nucleus, the hair of the comet, and the tail of the comet. Among them, the comet tail is the most eye-catching, which can be tens of millions of kilometers or even longer. The main component of the comet nucleus is ice, and there is a small amount of dust.

Comets and tails are formed by gaseous dust volatilized by the coma's nucleus by solar radiation. At the beginning of the 20th century, astronomers calculated that in 1910, Halley's Comet would return to the vicinity of the Sun and that the comet's tail would sweep over the Earth.

At the time, people were terrified, and some newspapers even declared that the end of the world was imminent. On May 19, Halley's Comet passed through the Earth's orbit, and the Earth passed through its tail unharmed. In fact, the tail of the comet is made up of very thin gases.

So, the Earth passes through the tail of a comet, like a swallow through the smoke of a cook, and it will not be affected in any way.

A sweep of the comet's tail over the Earth won't make a difference, but if the core of the comet, a major part of the comet, hits the Earth, it won't be so uneventful. Will the comet nucleus hit the Earth?

It follows that there is a possibility that a comet will hit the Earth. However, there is no need to panic, as the chances of such an event occurring are slim to none. However, astronomers take this issue very seriously.

For example, the United States has a near-Earth asteroid search program to monitor near-Earth asteroids and comets to prevent them from colliding with Earth. Modern science and technology are highly developed, once a comet is found to collide with the earth, it is also possible to launch a non-penetrating and carry nuclear bomb to try to change its orbit and avoid colliding with the earth.

Yes and twice. In 1908, the Tunguska region of Siberia, Russia, which destroyed 2,000 square kilometers of forest, is thought to have been caused by the shock wave of a meteorite with a diameter of 100 meters above the ground. The meteorite rain that occurred in Jilin City in northeast China in 1976 proved to be an asteroid formed in the asteroid belt of 4.6 billion years ago, and collided with other stars in orbit 8 million years ago, and a large explosion occurred and broke away from the asteroid belt and fell to the surface of the earth.

A comet is a celestial body that enters the solar system and orbits the sun in brightness and shape depending on the solar distance. Comets are divided into three parts: the nucleus, the coma, and the tail. The comet nucleus is made up of icy material, which sublimates as the comet approaches the star, forming a hazy comet and a tail of thin material around the ice core.

Due to the pressure of the solar wind, the tail of the comet always points away from the direction of the sun to form a very long tail of the comet. The tail of a comet is generally tens of millions of kilometers long, and the longest can be hundreds of millions of kilometers. Comets are shaped like brooms, so they are commonly known as broom stars.

The orbits of comets are mostly parabolic or hyperbola, and a few are elliptical. More than 1,700 comets have been found orbiting the Sun. The famous Halley's Comet orbits the Sun for 76 years.

On February 21, 2014, a team of researchers from Kyoto Sangyo University in Japan discovered the presence of ammonia on a comet. According to the latest reports, scientists have recently found some chemical residues belonging to the comet "67P Chulyumov Grashimenk" on board the Rosetta spacecraft.

Scientists used detectors to analyze these chemicals and found that the main components were ammonia, methane, hydrogen sulfide, hydrogen cyanide and formaldehyde. From this, the scientists concluded that the comet's smell smelled like a combination of rotten eggs, horse urine, alcohol, and bitter almonds.

There has been, the most famous comet in history that hit the Earth's source eventTunguska Great**It is thought that a comet hit the Earth.

Yes Many craters have been found on Earth, the largest of which is in Mexico

It seems that there are none, but many craters have been found on the earth, the largest of which is in Mexico (it seems to be), and it is very likely that the extinction of dinosaurs and other creatures is due to this reason.

It is very likely that life on earth has been destroyed many times and then reborn, and whether this crisis can be resolved depends on the development of human science and technology. Science and technology are not only the primary productive forces, but also the primary combat strength.

According to the records of experts and scholars, there has never been a comet hitting the earth!! But before the advent of human beings, no one can say.

Of course there is, and there are many times.

In the early morning of June 30, 1908, a celestial body with a huge fireball flew over the Tunguska region of Siberia, about 800 kilometers northwest of Lake Baikal. Charlotte's fireball shines brighter than the morning sun, and the thrilling roar reaches 1,000 kilometers away. Subsequent investigations have shown that this is most likely caused by a comet hitting the Earth.

The comet will first rub against the atmosphere to produce sparks, and the speed will slowly decrease, the small comet will rub away, and the large one will fall straight down, forming a meteorite or meteorite.

I think that if it really happens, it will take at least a few trillion more years for the earth to adapt to the activities of living things, and microorganisms and viruses will dominate the new earth, but it is not excluded that human beings will evolve again, but it is difficult to say whether apes or orangutans will appear at that time, and it can be said that the probability of human reappearance is almost equal to 0

Asteroid experts may be the most popular scientific researchers this year, and they have issued warnings of "heaven and earth collision" again and again, causing anxiety and panic in the world again and again. In September this year, astronomers at Cornell University in the United States suddenly announced that an asteroid codenamed 2000QW had "grazed" the Earth a week ago, and scientists did not realize it until five days before it flew to the Earth. After a false alarm, scientists have come to a thankful conclusion that if the asteroid hits Earth, it could wipe out 1.5 billion people!

Hoyle was a British astronomer. He believes that the ice ages that have occurred on Earth are likely caused by comets colliding with Earth. Because the center of the comet is an ice core, which is formed by freezing water, hydrogen cyanide, acetonitrile, carbon dioxide, etc., and dust is mixed in.

When a comet crashes into the Earth, it immediately scatters a large number of fine particles into the atmosphere, and even one hundredth of the dust of a small comet weighs 100 million tons. The dust poured down from all over the world, causing a sharp drop in the amount of sunlight on the earth, a drop in land temperatures, and water vapor turning into hail and falling. In this way, it will not be long before the land will be covered with glaciers.

Yuri's view is the opposite of Hoyle's. He believes that if the comet nucleus really collides with the earth, due to the effect of compression and heating, it will produce **, and its energy will become **energy and heat energy, so that the temperature of the earth's atmosphere will increase by 200. If the nucleus of the comet falls into the sea, the temperature of the sea water rises.

Within the reach of the comet, it will become a "scorching hell", and living things will be destroyed. If there are survivors who are given the right opportunity to reproduce, then a new era of species has begun.

Theoretically, it is possible. For example, in 1994, Comet Shoemaker-Levy 9 hit Jupiter. It was an event that caused a sensation in the astronomical community at the time.
