Ruan Lin once again approached the porthole and looked at Gliese 581, which was gradually moving away.

"Dr. Nguyen, according to stellar ranging, Gliese 581 is about 2.4 light-years away from Gliese 667. The voyage is expected to take 119 years. ”

"During the voyage, he continued to delve into quantum-photonic computers and decimal problems with me."

After saying the last sentence, Ruan Lin's consciousness returned to the quantum computer. The current situation made him a little anxious: the fleet was getting bigger and bigger, and his computing power was almost out of reach, and the most urgent thing to solve at present was the development of new computers and the replacement of the base system.

With the confluence of the Titan, the entire fleet has turned on its engines once again, and this time the destination will be a temporary home.

With only 0.47 light-years left to Gliese 667, the brightness of one star is visible to the naked eye, but this is only an occultation phenomenon, and the appearance and brightness of the other two stars are completely obscured by it.

Gliese 667 is like the original Proxima Centauri, α β. It is also a three-star system.

Gliese 667A and B are two orange dwarfs with an average brightness of 8.5% of the Sun, but they do not have any planets.

One of the members, Gliese 667C, is a red dwarf star, but there are as many as 6 planets, which is why wit chose this place for development.

At the same time, this three-body system also operates in accordance with the law, and they are not an irregular three-body system.

There is an eccentric orbit between the two brightest members of the system, Gliese 667A and Gliese 667B, with the two stars closest to each other only 5 AU apart and an orbital period of about 42.15 years.

The trajectories of A and B are extremely interesting: they first distance themselves from each other to form a straight line, then quickly close the distance, wrap around each other twice and then separate again.

Gliese 667C, orbiting the two brighter member stars, is farther, at least 230 AU away from the couple.

It is also the same "licking dog" as Proxima Centauri, and can only watch the couple love from the sidelines, and can never get close to them.

In addition to the three star systems that are gravitationally constrained by each other, it also includes a fourth optically close member, but this fourth member is not gravitationally constrained by the three star systems mentioned above.

At the last 0.2 light-years, the solitary Gliese 667C is already in plain sight, and it appears even more faint in front of the light of the two orange dwarfs.

But its 6 planets are proud of it, and it is also a star system favored by the heavens.

In 2032, Glise 667C has been officially identified as having six planets, of which at least three are classified as rocky planets, two are classified as gas giants, and the remaining one is oceanic.

The conditions for development are unparalleled, but the scope of this star system is incredibly small: 6 planets are almost crammed together, and the farthest planet from Gliese 667C, 667Cg, is only the distance from the Sun to Mercury! Optimistically, at least 3 planets are permanently tidally locked by Gliese 667C.

Ruan Lin immediately set the goal: "wit, we need to lay a base in Gliese 667Cc, this is the best starting point!" ”

With only 0.7 AU left at Gliese 667C, the farthest gas giant is visible to the naked eye.

The planet is dark orange in color, and the more it looks, the more it looks like a large orange about to decay, and the surface is not as ornamental as Jupiter.

"The distance between them is too close, and if the scope of the solar system can be compared to a large villa, then Gliese 667C is one of the small bedrooms."

Ruan Lin began to miss the solar system again, and his hometown was incomparable to other star systems.

The solar system and the earth are all unique.

On the final journey, Ruan Lin did not continue to look at the other planets, and the anxiety in his heart once again appeared, and he longed to land on the land of the planet.

The appearance of Gliese 667Cc gradually appeared before Ruan Lin's eyes: it is a rocky planet with 6.5 times the standard mass of the Earth, it is in the habitable zone of the star system, and it also has a thick atmosphere.

In fact, it bears an 85% resemblance to Earth.

"The large ships have come to a standstill in the geostationary orbit of the planet, and the entire fleet is starting to slow down."

It is now 50,000 kilometers from the surface of the planet, and all but the meteor-class destroyers have come to a standstill.

The expected tidal lock-in situation did not occur, and the planet turned out to be day and night!

Through the thick clouds, it is sunset.

Looking down, the surface of the earth is full of mountains and ravines, interspersed with large and small lakes, and in some areas there are large grasslands.

To the right of the porthole, the clouds seemed to be within reach, and the entire sky was dyed a transparent orange, mixed with some girly pink.

The rest of the ships gradually stopped at the relatively flat terrain, and Ruan Lin was already waiting at the hatch, he wanted to see the scene of the three-day volley again!

As the hatch opened, so did the hint of WIT:

"The Gliese 667Cc will receive electromagnetic radiation in a wider band than the Earth's surface, with an average surface temperature of 4.25 degrees Celsius, which is higher than the Earth's average temperature: -18.85 degrees Celsius."

The oncoming glow of Gliese 667C, which is about three times the size of the Sun seen from Earth, receives 90% of the radiation flux on the planet's surface.

To its right is the light of two orange dwarfs, which are at the farthest distance apart at the moment, and the intersection of the two points can form a straight line.

With three stars shining on the planet at the same time, you won't get tired of watching it no matter how many times you look at it.

"Why isn't it tidal locked? wit。 ”

Ruan Lin was very puzzled by this, it was so close to the parent star, it was impossible for the sun to rise and set.

But instead of looking up the database, he stared at the three stars in the sky.

WIT replied: "According to the analysis, the planet may have suffered a massive celestial impact shortly after its full formation, and its rotation and revolution speed were altered.

Or maybe it's because the planets of the star system are too close to each other. Gliese 667Cc is only 0.031 AU away from 667Cf, and the distance between them does not exceed the Loch limit of the two planets.

For objects whose relative distances change regularly, the tidal locking state will appear or be lifted at a predetermined time.

Without taking into account the influence of other celestial bodies, the Moon will tidally lock the Earth in about 50 billion years, and the Earth and the Moon will stare at each other for a while, then the Moon will slowly move closer to the Earth, and the Earth's rotation will slowly accelerate and release the tidal lock. ”
