"There are six planets?" Hu Bin's eyes lit up like a 120-watt light bulb, "Quick, let me see!" ”

The astronomical community has determined the universality of planets more than 100 years ago, but planets can only be determined indirectly, and the opportunity for direct observation is very rare.

When the expeditionary force arrived at Proxima Centauri, others didn't have any special feelings, but Hu Bin was different, because he knew that this was the first person in astronomical history to directly observe stars and planets outside the solar system with the naked eye.

Hu Bin directly ignored the fleets of the United States and Russia - although the fleets of the Americans and Russians were one step ahead, the distance of the Wolf 359 was long, and the arrival time of the Russians should be about the same as the time when the expeditionary fleet arrived at Proxima Centauri, and as for the Americans, they would not be able to reach Gliese 581 in half a year.

Hu Bin threw himself on the screen in everyone's surprised gaze and exclaimed: "Great, there are so many planets!" ”

"Staff Officer Hu, do you think these planets have any value in transformation?" The purpose of this trip was to find a planet suitable for colonization, Ye Fei felt that Hu Bin's state was not normal, and immediately reminded him dutifully.

"Oh, yes, that's good." Hu Bin stabilized his excited mind, "Please give me the observation data." ”

As soon as the voice fell, the complex data was immediately displayed on the screen in front of him.

Hu Bin looked at it carefully, clicked on the screen and said: "You also found that A is a little larger than the sun, and B is a little smaller than the sun, and together they are exactly twice the size of the sun...... The two planets of B are about the same size as Earth, but they are too close to the stars and have been tidally locked, so there is absolutely no value in transforming them. ”

"What is Tidal Lock?" The black bear asked curiously.

"The moon is always facing the earth because it is close to the earth, and Mercury is close to the sun and always facing the sun, which is tidal locking." Hu Bin tried to be as intuitive as possible, trying not to use an accurate but obscure explanation, "Centaur αB and its planets are completely hopeless. ”

Hu Bin stretched out his hand and crossed the star on the right out of thin air: "A and its three planets...... Well, the second planet is 1.3 astronomical units away from the star, which is exactly in the habitable zone, and the third planet is in close orbit to the second planet, which is also within the habitable zone...... Give me detailed data on these two stars! ”

The first mate Fu Hongye handed Ye Fei an inquiring look, Ye Fei nodded slightly, and the data in front of Hu Bin immediately changed.

As the captain of the Celestial Army, Ye Fei also has a lot of astronomical knowledge, but the knowledge he has mastered is mainly related to combat, and the knowledge he has learned does not include how to judge whether a planet is in the habitable zone, otherwise how can there be Hu Bin's business?

Hu Bin's fingers drew and drew on the screen: "The mass of the third planet is too large, and the gravitational force is at least 1.7 times that of the earth, so it is worthless; The second planet is only a little larger than the Earth, and there is hope! Is the orbital data out? ”

"The time is relatively short, and the orbital data is still being calculated." Ye Fei replied, "Counselor Hu, the distance of the second planet is appropriate, but does the other star have no effect on it?" ”

"Impact? What impact? Hu Bin asked inexplicably.

"I'm talking about temperature." Ye Fei said, "Everyone knows the myth and legend of Hou Yi shooting the sun, right? Isn't it a little bit of an impact to hang two suns in the sky? ”

Two stars about the size of the Sun are crammed into the same galaxy, and it feels like a pair of twins are crammed into the same **.

"Oh, that's what you ask." Hu Bin pushed his glasses, "There must be an impact, but it's hard to say how big the impact is." ”

"Hey, don't sell it, say something useful." The black bear urged impatiently.

Hu Bin said without looking back: "When these two stars are closest to each other, they are also 11.2 astronomical units, which is equivalent to the distance from Saturn to the sun. ”

The black bear couldn't help laughing: "It's just a small bright spot, not much bigger than just jumping." ”

"That's right!" Hu Bin smashed his fist in the palm of his hand, "I don't need to say, you also know what kind of environment Saturn is, when B is closest to the second planet, it is also about 10 astronomical units, plus star B is a little smaller than the sun, and the heat radiated to the second planet is very limited, so it is more practical to worry about not being able to sleep with multiple suns at night." ”

After hearing this, everyone suddenly realized, and Hu Bin nodded to the giant planet at the gravitational equilibrium of the two stars: "Actually, I think this planet is the most valuable for research." ”

"For what?" The black bear asked very cooperatively, and was immediately glared at fiercely by Ye Fei.

The black bear smiled, they were all old brothers, and he knew that Ye Fei would definitely not take this little thing to heart.

As soon as Hu Bin heard that someone was picking up, he suddenly became more interested: "The sun is the absolute center of our solar system, but there are two stars orbiting each other, neither of them is actually at the center point of this galaxy, and the Lagrang day point between the two stars is the real center of this galaxy!" ”

The image of two suns orbiting a small giant asteroid immediately appeared in everyone's minds, and what was even more joyful was that the two suns each carried a planet, and the giant planet in the center wore a hat-like halo in addition to a group of moons......

"The orbital data is out!" Fu Hongye shouted excitedly.

"Show me!" Hu Bin couldn't wait to squeeze over, but immediately realized that the data would be displayed on the screen, and quickly turned back, just in time for the data update.

"Ahelion point 2.6 perihelion point 0.8......" Hu Bin's face changed, and he suddenly collapsed to the ground like a deflated ball.

"Staff Officer Hu?" Ye Fei was stunned for a moment, "Quick, call a military doctor!" ”

"No need." Hu Bin waved his hand weakly, "I didn't have anything to do, I didn't expect it, I didn't expect it, I thought we were lucky enough to find a planet suitable for transformation, ridiculous, ridiculous, how can I believe in something so ethereal?" ”

Everyone looked at each other, and Hu Bin's appearance seemed to be stimulated by something.

"Staff Officer Hu, what are you ......" Ye Fei didn't want Commander Lu's red man to have an accident on his ship, so he immediately glanced at the black bear, and the black bear nodded knowingly, meaning that the military doctor had been notified.

Hu Bin stood up with his arms propped up, looking at the second planet on the screen with complicated eyes: "Its orbit is elliptical, and the perihelion is only 0.8 astronomical units, which is nothing, controlling the greenhouse gases in the atmosphere can ensure that the temperature is suitable for human life, but the aphelion is 2.6 astronomical units away, which has exceeded the boundary of the habitable zone." Let's go, there's nothing to see here, let's go back. ”

Ye Fei couldn't help but smile bitterly, this time it's good, and he ran in vain: "Go back the same way, I need to calm down, first mate, you will command." ”
