(Ps: I wonder how many people still remember the Lc element of Chu Siyuan when deducing the third equation?)

——

Taoling Town is holding a six-month space fair, and the whole world is reporting that human space industry has entered a great new era. A irregular celestial body with a maximum diameter of 6.92 kilometers seems out of place in the asteroid belt.

It seems that it is not the "native people" of the asteroid belt, but eventually leaves the main belt, that is, it leaves from what people often call the asteroid belt, and goes with the sun.

The reason so many asteroids can be condensed in the same place without running around is that in addition to accepting the gravity of the star of the sun, they are also greatly affected by the gravity of the largest planet Jupiter.

The distinctive "abnormal behavior" of the incompatible asteroid shows that it is also affected by other forces. Its orbit at this moment indicates that it will deviate from the main belt area and become a near-Earth asteroid.

At this moment, under the spatial coordinates of the entire solar system, when it flies inward, Mars will "accidentally encounter" it, and this irregular celestial body will also change its orbit due to the influence of Mars' gravity.

The current orbital position of Mars shows that this asteroid will not be captured because the gravity of Mars is not enough to capture it, but it will be further accelerated by Mars' gravity.

It will be further "turned" toward the Earth by Mars. The closest Earth and Mars are about 55 million kilometers. The orbit of this asteroid can be calculated. The final result shows that it will be captured by the gravity of the Earth.

...

Purple Mountain Astronomical Observation Station.

A young doctoral student is sitting in front of a monitor observing the star map. This is the star map taken by Schmidt telescope today, mainly observing the situation of near-Earth asteroids.

The so-called near-Earth asteroids are very easy to understand by looking at the literal meaning. "Nearth" means that their orbits are very close to the earth. They are relatively special asteroid groups that deviate from the main ring.

So far, according to the latest release of the International Asteroid Center website, through global joint testing, astronomers have discovered and established 1,672 near-Earth asteroids that have potential threats.

As early as 65 million years ago, dinosaurs that dominated the earth for 150 million years disappeared. Astronomers have guessed that there are two possible hypotheses:

First, the supernova erupted, which is approximately equivalent to 10^24 hydrogen bomb energy, causing the dinosaurs to become extinct.

The second is that the asteroid hits the earth.

"Hmm? Why is there one more?" The young doctoral student was stunned for a moment, but instantly realized an incredible discovery. He immediately suppressed his excitement and then called out another old star map for comparison, comparing it over and over again.

The final result made him extremely sure that he should have discovered a new Near-Earth celestial body. He was so excited that he couldn't help but call: "Professor, professor, I have made a major discovery. I may have discovered a new Near-Earth asteroid."

"What? I'll come here right now!" A surprised voice came from the phone, and then hurriedly hung up the phone, and after coming to the observation room, he said bluntly: "Where is the star map?"

"Here..." The doctoral student called out the two-point star map, and the professor began to compare and murmured after a moment: "Yes, you may have really discovered new NIE objects, but it needs further confirmation. Quickly, we need more reliable evidence to observe it with a space solar telescope."

...

At the same time, the NASA Space Center in the United States also discovered this uninvited guest through the "Web Space Telescope".

"The track has been calculated!"

Another white man in a suit came to the console and put his hands on his hips with one hand on his hips, saying, "How is the result?"

On the display panel is the spatial layout image information of the solar system. A man sitting in front of the stage swallowed and said, "The calculation results show...... 553 days later... hit the earth!"

The white man looked relaxed, but when he heard this, he almost fell down, and exclaimed: "What did you say? Hit the earth?"

The sitting man nodded, supported his glasses and said solemnly: "According to its current orbital speed, it should eventually pass by 730,000 kilometers away from the Earth. However, due to the existence of Mars, it will be affected by Mars' gravity in 103 days and will change its orbit in 103 days. The new orbital calculation results show that it will be captured by the Earth's gravity in 547 days and will eventually hit the Earth. Our calculation results are so refined that it will hit the Pacific New Zealand area."

"My God..." Charlie was confused. A nearly 7-kilometer-diameter asteroid would hit the earth in one and a half years? The meteorite that hit the Gulf of Mexico 65 million years ago led to the extinction of dinosaurs. Although the 7-kilometer asteroid ladder was not as good as the 7-kilometer asteroid, it was still enough to eliminate all living things on the surface of the earth, including humans.

He instantly realized that NASA could observe, then ESA could observe, and Chinese could also observe.

"Quick, contact the White House immediately. We must contact other astronomical units in the world as soon as possible. This message must be prevented from being leaked."

"Sir, the people have the right to know, and I think we should make it public to..."

"Shut up Corris, if you say such an idiotic thing again, I will send you to prison with your own hands, and you all."

...

After 36 hours, while media around the world were reporting and hotly discussing the cause of human space and the first space fair, the outside world did not find that at this time, many aerospace agencies and astronomical institutions in the global aerospace field sent a group of extremely important figures to fly from all over the world on special planes to China, to be precise, to go straight to Huasheng Technology.

Huasheng Technology Headquarters.

At this time, Li Chuan was having lunch at home, and Xiaomu's voice sounded: "Dad, there is an emergency news that a large group of important figures from aerospace or astronomical institutions are coming towards the company and are expected to arrive at the headquarters entrance in twenty minutes."

At the same time, a huge black fleet lined up in a long queue and drove on the main road of the Taoling Town Highway. This scene also attracted the attention of many people, and ordinary people did not pay too much attention. Now this scene is not new in Taoling Town. The difference is that the convoy this time is a little bigger.

However, it attracted the attention of the reporters here. The train convoy was too long, with more than 30 black cars in a row, which was really eye-catching.

What many reporters regret is that people outside the car cannot see who is sitting in the car, but the car can clearly see the scene outside.

"Taoling, Space House... This may be the place to solve this crisis." A white man sitting in the back seat in a car in the convoy muttered to himself as he looked outside. At this time, Taoling Town was holding the first space fair, everything here seemed to be related to the sky.

The white man on the car is the current director of NASA in the United States. This time he hopes that Li Chuan and Huasheng Technology can become saviors without any jealousy, because he has to accept that other space agencies in the world seem to be unable to deal with this crisis. Huasheng Technology and Li Chuan may be the biggest reliance on solving this common crisis in mankind. Just because of the existence of Yuntian-class aircraft, perhaps Li Chuan has other advanced technologies.

That's why this huge convoy carries with important figures from aerospace agencies in Taoling Town, which may represent the ultimate alliance of world aerospace forces.

The time is too urgent and the incident is too terrible. It is not even exaggerated. The survival of human civilization has entered the countdown of the last 553 days.
