◆ Introduction to the film:

Asteroid experts may be the researchers who attract the most media attention this year. They issued warnings of "big collision between heaven and earth" again and again, causing anxiety and panic of the world again and again. In September this year, astronomers at Cornell University in the United States suddenly announced that an asteroid code-named 2000QW had brushed the earth a week ago, and scientists didn't notice it until five days before it flew to the earth. After a false alarm, scientists came to a gratifying conclusion: if this asteroid hit the earth, it could destroy 654.38+05 billion people!

A wave of unrest, another wave. 165438+1October 3, an astronomical team in Hawaii, USA, announced at the Celestial Federation that an asteroid code-named 2000SG344 may hit the earth in 2030, and its impact energy is equivalent to 100 Hiroshima atomic bombs, which caused public outcry. But just one day later, astronomers urgently corrected their previous judgment and thought that the possibility of "meeting" with the earth was about one in a thousand, and it was in the more distant 20 17 years. Nevertheless, the discussion about the impact of asteroids on the earth is not over, and more and more people are beginning to pay attention to the possibility of "a big collision between heaven and earth". British scientists even formally submitted a report to the government, suggesting that the government must actively take preventive measures. China Purple Mountain Observatory also decided to invest 20 million yuan to build the largest asteroid telescope station in China.

The reporter was confirmed by the Beijing Observatory of Chinese Academy of Sciences yesterday that this asteroid is indeed the most dangerous asteroid ever discovered by human beings. Its orbit is very similar to that of the earth, with a time of 354 days around the sun (the earth cycle is 365 days). Zhu Jin, the only asteroid observation researcher at the Chinese Academy of Sciences, told reporters that this dangerous asteroid will not "collide head-on" with the Earth because its turn is consistent with the Earth. The latest observation shows that in 20 17 years, its orbit will "coincide" with the earth's orbit, but it is hard to say whether the two stars will meet. With further exploration, perhaps this terrible conclusion will be ruled out.

According to researcher Zhu Jin, at present, the international astronomical community does not know much about this asteroid. Astronomers only judge whether it must be an ordinary asteroid by its brightness. But if it is a metal object, the volume is much smaller. At present, observers can't see its material structure. It may be a stone or a propeller fragment of a human spaceship in the 1970s.

/kloc-Leo Biederman, 0/4 years old, never thought that he would make such an earth-shattering discovery. While observing the sky, he came across the "Comet Biederman" named after him later, but scientists soon found that this comet was about to hit the earth violently. Jenny Lai Na, the new TV host, was busy reporting the sex scandal that led to the downfall of the finance minister, and found the news that a comet would hit the earth, so Jenny was "invited" by the president to have a private talk. The president asked Jenny to keep this secret for two days on condition that she reported it exclusively. At the press conference, President Baker announced that he would send a special team into space to destroy the comet that hit the earth. Former famous astronaut Tanner was ordered to lead five astronauts to the comet in the Messiah spacecraft, and set a nuclear bomb on the comet to detonate or deflect the comet, thus saving the endangered earth. In the next few months, everyone is facing the coming disaster, and everyone is trying to find the meaning of life. In order to prevent the extinction of all living things, the American government specially built an underground shelter similar to Noah's Ark, which allowed a few people and animals to survive. After the failure to destroy the comet with a nuclear bomb, the astronauts resolutely decided to drive the Messiah spacecraft with a nuclear bomb into the comet on their way back to Earth, in exchange for the safety of human beings on earth, but a small comet still hit the earth, causing an unprecedented disaster. ...

According to Brian G.Marsden of Harvard Smithsonian Center for Astrophysics, in 2028, a celestial body with a diameter of 1.5 km (1 mile) will pass 50,000 km (30,000 miles) away from the Earth, which is an astronomical necessity. In fact, researchers were not sure that asteroids would not hit the earth. The next day, astronomers discovered the celestial photo taken by 1990 and recalculated its orbit. They calculated that it would pass about 1 100 million kilometers away from the earth, which is more than twice the distance from the earth to distance to the moon.

Apophis is one of nearly 800 potentially threatening asteroids known to astronomers and one of the few celestial bodies that astronomers hope to further study in detail.

Apophis is a near-earth asteroid orbiting the sun, with an irregular shape, a diameter of only about 320 meters and a mass of about 42 million tons. It was discovered in June 2004, and then it lost its trace until it was discovered again half a year later. In 2004, on Christmas Eve, scientists calculated in the Near-Earth Object Project Office of NASA that Apophis would pass the Earth on April 13, 2029. Scientists have continuously observed the Apophis asteroid, and the estimated data show that by 2029, the distance between the Apophis asteroid and the Earth will be 18640 miles, which is thousands of miles closer than the distance between most communication satellites and the Earth.

When Apophis approaches the earth, its speed is 5.9 kilometers per second. If it hits the earth, it will generate energy equivalent to 1 1 10,000 Hiroshima atomic bombs, which is equivalent to instantly destroying the whole city of new york and its surrounding areas; If it hits the ocean, it will trigger a devastating tsunami, which is even more violent than the Indian Ocean tsunami in 2004. Therefore, astronomers described Apophis as a deadly enemy.

On April 13, 2029, Black Friday, millions of people will go outdoors, look up and marvel at their good luck. The asteroid Apophis will pass by the earth, and a light spot will cross the night sky, faster than many satellites and brighter than most stars. On April 13, 2029, the asteroid Apophis will fly over the earth at an altitude of 30,000 kilometers. In contrast, the orbital height of geosynchronous satellites is 36,000 kilometers. At the nearest distance, this asteroid will be as bright as a third-class star. Even under the city lights, it is visible to the naked eye in Africa, Europe and Asia. No one has seen such a bright asteroid in space since records began.

Scientists predict that in 2029, when Apophis whizzes past the earth, the earth's gravity will twist the celestial body into a complex state of rotation and swing, and the torque generated by gravity may also tear Apophis.

Such an event has never been witnessed before, and scientists will get the best opportunity ever to observe how the gravity of the earth affects the motion of asteroids. This kind of research is of great reference value for scientists to deal with other celestial bodies that are in danger of colliding with the earth, because similar state changes will occur when small celestial bodies approach the earth.

When the asteroid Apophis passes the earth at a height of more than 30,000 kilometers from the earth's surface in 2029, its own state and orbit will change due to the gravity of the earth. This change is enough to cause it to "hit" the earth seven years later, in 2036. The force generated is enough to make Texas disappear, or two European countries disappear. In such a devastating impact, it is difficult for life on earth to escape this robbery. A Russian scientist predicts that one day in 2036, an asteroid will hit the earth, and the energy generated by its explosion is equivalent to 1 10000 atomic bombs exploding in Hiroshima, and life on earth will be destroyed.

At the symposium on the safety of asteroids and comets held in St. Petersburg, Russia, Russian astronomer Shor made a model. Suppose Apophis hits the Pacific Ocean, it will set off a 200-meter-high wave, and the dust raised by its shock wave will cover the earth14 area, where animals, plants and humans will die because of cold and the destruction of the food chain. ...
