"I haven't heard of any good meteorites in Fujian, since the situation said by the other party is so true, it is entirely possible to find the meteorite, you ask the other party, have you taken a video of the fire meteor. ”

Zhang Gaogong replied.

He Gang hurriedly called the phone back.

In the process of He Gang's phone call, Zhang Gaogong fell into deep thought, in fact, he was also skeptical, people have seen many meteorites fall, but nothing can be found in the craters they formed.

Historically, only one meteorite has been witnessed exploding in the sky and forming a large crater.

Also in Siberia, in February 1947, near Mount Alin in Sikhotan, hundreds of observers saw a fireball as bright as the sun passing through the sky.

In this glorious five-second display, a rainbow of colors appeared, and finally turned red, and the lumberjacks who were closer saw the meteorite explode into pieces, and with a thunderclap, they fell into the forest.

The shock wave was felt by residents 160 kilometers away.

The meteor shower fell into the field, which is 2 kilometers long and 1 kilometer wide.

Scientists later calculated that the meteor exploded about 6 kilometers above the Earth's surface.

If it had been in primitive times, this scene would have induced prostration and religious sacrifices. The government of the former Soviet Union also issued commemorative stamps for this purpose.

The site of the impact was very different from that of the Tunguska.

Thousands of meteorite fragments were found, the largest of which had a mass of more than 1,800 kilograms, some of which pierced tree trunks and branches.

The vast majority of meteorite fragments were found in numerous craters, the largest of which was 26 meters in diameter and 6 meters deep.

Interestingly, the largest meteorites were not found in the largest craters.

Although it crashed into the largest crater, it shattered on impact.

Meteorites with lower kinetic energy can only form small craters, but they remain intact.

The total mass of the impacts is estimated at about 63 tons, but the combined number of meteorites found is only 20 tons, and most of the rest have been vaporized or buried deep in forests.

The difference in the properties of the Sikhotan Alin and Tunguska meteorites lies mainly in their different compositions.

Tunguska may have been a stony meteorite, while Sikhotan Alin was iron and exploded very close to Earth.

Scientists have been able to calculate the orbit of the Sikhotan-Alin meteorite before the collision. It comes from the major asteroid belt, with an apogee of about 22 AU and perigee within the Earth's orbit.

What will happen to the asteroid that hit the Earth this time?

Zhang Gaogong clearly remembers that there are countless craters on the earth where human beings reproduce.

About 3,000 years ago, a huge meteorite landed on the Estonian island of Shalemaa, and the meteorite sank into the ground, forming a crater-like crater on the surface, with a diameter of 110 meters and a depth of 12 meters.

Over time, a lake gradually formed.

On the island of Shalemaa, there are seven other smaller crater-like craters.

Scientists have found that this may be the result of a huge meteorite exploding in the air before it falls to the ground, and the seven smaller craters are formed by the debris that fell during the explosion.

Ten craters have been found in Canada, several of which were also formed tens of thousands of years ago. In the Arab region, in Argentina, there are such craters.

In Chile, not far from the Argentine border, there is a large crater, which is believed to be the third largest crater ever found on Earth.

With a diameter of 480 meters and a depth of 30 meters in the center, scientists believe that this crater was formed about 5 million years ago.

There are many traces on Earth, such as those left by huge meteorites when they landed on the island of Shalemaa or in the Sikhotan and Mount Arin areas. Further scientific exploration of the Antarctic revealed a large oval-shaped crater beneath the 1-kilometre-thick ice near the Australian end of Antarctica.

Scholars believe that it is also a crater.

When the meteorite fell, the fragments of the meteorite that exploded fell in Australia, the Philippines, and Indonesia.

The meteorite's flight was abruptly terminated by its impact on Earth, releasing a large amount of kinetic energy, which was converted into high pressure and heat.

The amount of energy released upon impact depends on the size and speed of the flying object.

"Zhang Gaogong, the other party said that there was a video. ”

He Gang's reply interrupted Zhang Gaogong's thoughts.

"Alright, let's go. ”

Zhang Gaogong immediately wanted to leave.

"Xiao Huang, come with us to have a look, maybe you are lucky enough to pick up a meteorite. ”

He Gang sent out an invitation.

Kowloon did not hesitate for a moment, and immediately agreed to go together.

This time it was He Gang who drove his Beijing jeep all the way forward, and Kowloon's car stopped at the gate of He Gangshiguan, and this time the direction of going was to Fuzhou, He Gang drove fast and steadily, and it took nearly three hours to reach the destination - Gangtou Town.

Standing on the side of the road to greet He Gang's uncle, he claimed to be surnamed Wang, an old friend of He Gang, and the two did not need to be polite when they met, Uncle Wang directly turned on the mobile phone video taken last night, Zhang Gaogong According to the direction of the meteor's flight, he judged that this would definitely bring a meteorite rain.

According to the direction of the meteor shower's flight, Zhang Gaogong determined that the meteorite fell in the farmland.

He asked Uncle Wang to lead the way, and the people followed closely and walked to the fields.

Many villagers along the way were very curious, what is this Uncle Wang going to do?

There are also people who understand, the explosion last night was really strange, and today an expert came to the door, could it be that something good happened?

So, these people followed unhurriedly, wanting to see where Uncle Wang and the others were going, and whether they had found something extraordinary.

Uncle Wang walked forward in the direction guided by Zhang Gaogong, and the more he walked, the more strange he became, how did he go to his own field?

Zhang Gaogong came to the edge of a large farmland in the back mountain, and there were several farmhouses on the side, he paused, and he asked the farmers who came with him if there was any movement last night.

Some villagers said that it was dark late in the local area, and at this point around 7 o'clock that night, many people were still chatting and drinking.

Some homes have their curtains open and a spectacle through the windows.

Villagers' description: They first saw that the sky was as bright as day for about 10 seconds, and then they heard the sound of explosions, the roar of a large truck driven by a person, the "whining" sound like the wind blowing, and all kinds of "buzzing", "whirring" and "booming" sounds......

The grandson and granddaughter of villager Uncle Liu heard that "someone has smashed the house", and the two children, who were less than 10 years old, trembled with fear.

Uncle Liu's wife Yu'er said that she didn't have any enemies in her family, and she thought it was a drunk man who smashed the house.

After dawn, Yu'er's family found that a big hole had been smashed in the roof of their house, and a black stone had fallen into the living room on the second floor.
