Our sun is just an extremely ordinary star in the Milky Way. There are 200 to 400 billion stars in the Milky Way alone. The known universe has included the Milky Way of ten to eleven square meters, the order of magnitude. Over the past few decades, a series of astronomical observations have shown that the solar system we live in is just an extremely ordinary star system in the vast universe. There is no special place except the earth where we humans and other creatures live.

Centauri alpha is a three-star system, called Nanmen II in Chinese. This is the star system known as the closest to the sun. It is also the planet that is most likely to exist in life at present. It is also Yun Yi's destination. There are three stars in this galaxy. Alpha Centauri A and Alpha Centauri B are a pair of binary stars, forming a relatively stable binary system. The third star, Alpha C, is a red dwarf, also called Proxima C.

This planet is also an important source of inspiration for the work of "Three-Body Body". In the setting of "Three-Body Body", the three stars in the centaur galaxy are volatile, so the climate of the planet where the Three-Body Body is located is also extremely unstable. In the Three-Body Body world, sometimes two or even three suns appear in the sky, and the surface temperature of the Three-Body Body planets rises rapidly. Sometimes three stars appear at the same time away from the Three-Body Body planets, and the temperature suddenly drops, and even stones can freeze into powder. Just like the game that simulates the survival of the Three-Body Body Body, the arrival of disaster is always unexpected, and if you are not careful, it will destroy all civilizations and let everything on the planet start from scratch. In the novel "The Wandering Earth", when a disaster occurs in the solar system, people's first choice for escape from the solar system is also the centaur alpha.

What is the truth?

Nine months later, Yun Yi was quite expecting the destination that he would arrive soon. He had consulted countless speculations about Proxima Centauri when he was on Earth. However, unlike humans on Earth, he could immediately witness the real situation of this triad galaxy with his own eyes.

The gravity of the three-star may be too strong. The Ort cloud at the edge of the galaxy does not have countless meteorites and asteroids like the solar system. Their density is much lower than that of the solar system, but the range is much wider than that of the solar system. The spacecraft Yun Yi is riding has been flying in its range for several months, and he has not seen the dawn of flying out of this range.

"How long will it take to reach the destination in 'Yindan'?"

"Yindan" focused on studying the recipe and answered without raising his head: "I have been persisting for three months and several years. It's not too late to see how leisurely I am?"

"You are a robot, and I am a human. Besides, you have entered the Proxima Galaxy now. Can you let me see its structural diagram? I know you have these information. I didn't allow it before, but now you can use spacecraft to detect it. This is not a violation of the program, right?"

"Uh, you can check it out, as long as you don't be too surprised, there are many magical celestial bodies in the universe!"

Yun Yi didn't think the structural diagram of Proxima Star would surprise him, but he was indeed shocked when the film and television resources displayed on the big screen.

"Our destination is here. We used to call her Tiansheng Star. The three stars are close to Proxima Centauri. It is 1.8 astronomical units from Alpha Centauri A and Alpha Centauri B. It orbits Proxima Centauri, with a distance of 1.3 astronomical units, which is far away from the sun and earth in the solar system. You also feel that the solar energy of this galaxy is very sufficient. According to the original guess, there is no life planet in such an environment, but in fact, Tiansheng Star exists, and the environment is very good."

"Yindan" came to Yun Yi, who was still in a daze, and pointed at the galaxy structure diagram and introduced.

"And there are far more planets in this galaxy than the Earth. There are nineteen planets of different shapes, orbiting three stars, and the gravity of the three stars is involved in each other, maintaining a huge and balanced planetary system.

Except for Tiansheng Star, the other planets are not suitable for life and do not even have the value of transformation. The temperature here is too high."

"How did Shengxing develop into a life planet that day?" Yun Yi asked curiously.

"Yindan" did not speak, but brought the galaxy structure diagram closer first, and fully presented their destination Tiansheng Star in front of Yun Yi.

"Do I call God now? This universe is so magical!" Yun Yi said exaggeratedly, but this statement was not enough to express his shock.

"I know you don't believe in God, maybe you should be called God. Tiansheng Star has a diameter of 283,254 kilometers. The two on the earth are mostly. 59% of it is the ocean and 41% of the land, and the gravity is 1.8 times that of the earth. That is to say, a hundred kilograms of life must bear 180 kilograms of gravity on her surface. She is not suitable for ordinary humans on earth to survive. If it is a life that unlocks the gene lock, it will be completely unhindered.

This also proves that if genetic technology is not developed, it is very difficult for humans to enter space. Look at Tiansheng Star, it is like the earth is a beautiful blue life planet, but now even if humans on Earth discover it, there is no way for them to survive. Any herbivorous animal on the surface can take human life. The living environment determines their physical fitness. Perhaps their kind-hearted approach will take human life, and at least it will be the end of broken bones and disabled people."

Yun Yi's face turned a little dark, and the robot's tone was obviously sarcastic. It seemed that he had evolved too perfectly, and I don't know when he learned to speak in a sarcastic tone.

"What's going on with the three big satellites around him? Judging from their diameters, it's too wrong for them to say that the satellites are!"

The satellites Yun Yi mentioned are three planets orbiting the Tiansheng Star, such as the moon next to the earth, but the volume of the moon cannot be compared with these three, and the distance is much farther than the distance between the earth and the moon.

"This is the magic of the universe. Tiansheng Star, which is between the three stars, and its three satellites. It is really a coincidence to maintain the current structure under their cross-gravity. They are locked by tides like the moon, with only one side facing Tiansheng Star, which has no night. It rotates for 36 hours a week. Every twelve hours, a satellite blocks the direct sunlight and forms the night. This repeated alternation forms a 24-hour zone similar to the earth, but it only rotates by two-thirds."
