Alpha Centauri, aa, is frozen Saturn.

It is the earliest planet discovered by the extraterrestrial civilization project team and the last planet to arrive in the Centauri Alpha Galaxy.

The volume of the planet is about 125% of the earth and its density is 1.1 times that of the earth. After calculation, its gravity level is slightly lower than that of the Sand Star, about 118% of the earth's gravity. Its average orbit of the star a has reached 1.31 billion kilometers, so the temperature on the planet's surface is very low, roughly maintained between -210c and -160c.

"Why, frozen Saturn gives me a very peaceful and familiar feeling."

Lynn looked at the silver-white planet outside the porthole in a daze.

As the spacecraft of the Future approaches, the silver-white planet hanging in the dark universe becomes increasingly prominent.

At this time, Yuan Shichen, Smith and Lynn could see the texture of the surface with their naked eyes without using the observation equipment. Those were winding mountains.

Yuan Shichen stopped the work in his hand, and the moment he turned around, his eyes accidentally glanced at a very bright star in the distance.

That's the sun!

Yuan Shichen's heart trembled inexplicably. It was the light from the hometown of human civilization.

He couldn't help but say that his eyes were on that star and he knew that a loud voice came.

"After analysis, the atmospheric components of the Frozen Star are as follows: 9.1% carbon dioxide, 80.1% nitrogen, 6.9% oxygen, 2.1% argon, and 0.9% hydrogen."

Smith informed the other two of the other two of the analysis results of the atmospheric composition of Frozen Saturn.

"Compared with the atmospheric conditions of Sand Star, the carbon dioxide content is much lower and the oxygen content is 6%. Such an atmosphere mass is already relatively close to the atmosphere level of the earth." Yuan Shichen said thoughtfully.

"The surface atmospheric pressure is 1.5 Earth's standard atmospheric pressure. However, the surface temperature is too low, around -200 degrees Celsius," Smith continued.

"You can detect the water content again." Yuan Shichen suggested.

"OK!"

Ten minutes later.

"Oh my goodness, come and see!" Smith shouted in surprise.

“What’s the situation?”

Yuan Shichen and Lin En surrounded.

"Future feedback, there is a lot of water on frozen Saturn, oh no, it should be said to be a lot of ice!" Smith pointed to the screen excitedly, "Look at these plains!"

"This is" Lin Neng looked puzzled.

"These are completely frozen lakes and oceans!!"

"It's so shocking, it's like a frozen earth!" Lin Neng murmured to himself, "No wonder frozen Saturn gives me an inexplicable sense of familiarity."

"This situation is in line with previous guesses." Yuan Hashichen said slowly, "According to the binary gravity system model we established before, Frozen Saturn should not be in its current position at the earliest. Perhaps it was once in the habitable zone, but was gradually thrown by the gravity of the binary system to the edge of the star system over the long years. Moreover, in the near future, it will be completely abandoned and become a planet wandering in the universe."

"Can Frozen Saturn be the birthplace of the Creator's civilization?" Smith asked.

"It is possible that, even if it is not the origin, it will at least be an important residential planet." Yuan Shichen replied.

"What a pity, it has now become a completely frozen world." Lynn said with regret.

"Can there be life in frozen Saturn?" Smith continued.

"If Frozen Saturn had a complex and complete ecosystem at the earliest, then I believe there would be some simple forms of life that could survive," said Lynn.

"Oh~" Smith nodded in anticipation of the following.

"You can imagine what the earth will become if the sun suddenly disappears." Yuan Shichen made an assumption.

"I know this. If the sun suddenly disappears and the earth still exists safely, the earth and other planets in the solar system will continue to float without any ties like kites with broken lines. Because the universe is vacuum, the earth that has lost its gravity will fly straight into the depths of space along the tangent line of its original orbit and become a wandering planet." Smith said enthusiastically.

"Yes, we won't discuss the situation where the earth is affected by external forces during its wandering process. Then, without sunlight, the earth will slowly cool down, and the world will soon enter a cold winter. Within a week, the global temperature will drop to more than ten degrees below zero. At that time, whether we are in the original equatorial tropical areas or the Antarctic ice field, we will feel biting cold. Within a year, all freshwater lakes and rivers will freeze into ice, and the sea water will gradually freeze. Three or four years later, the vast and deep oceans on the earth will freeze into a huge ice cube." Harashi-chan added.

"That looks like the frozen Saturn in front of you." Smith said.

"If it is to become the current state of frozen Saturn, it will take a long time."

Naichen and Lin En continued to have hypotheses and discussions.

"After all the water on the earth is frozen, all the weather phenomena on the earth will disappear: there is no wind, rain, snow, clouds, hail..., the earth will become as quiet as frozen Saturn. However, the pace of cooling will not stop, and the earth will continue to cool down slowly."

"In millions of years, the temperature on the earth's surface will drop to about minus 200c and then it will not drop anymore, because the earth has a scorching core. When the heat emitted on the surface of the earth is equal to the heat absorbed from the core, the surface temperature will not drop again."

"As the saying goes, everything grows by the sun. If there is no sunlight suddenly, the entire earth's ecosystem will collapse soon: first, all kinds of plants die one after another, then vegetarian animals that rely on plants for their lives die, and finally carnivorous animals die. According to the pyramid of the food chain, the entire ecosystem will disappear one after another. The animals that died early are animals in the ocean, because as the sea water continues to cool down, animals in the ocean will be frozen to death and frozen in huge ice cubes, and perhaps, they will not rot for millions of years."

"Animals on land should not die soon. They may continue to survive for several years or even decades. The first ones are cold-blooded animals. They will fall into hibernation and die slowly, and will never wake up again. After the earth loses its sunshine, it will soon become a "big refrigerator". Plants, especially those woody plants, will be "refrigerated and kept fresh" for a long time. If herbivores with thicker fur can withstand the cold, they will not have to worry about food for at least a few years. Decades later, herbivores and most carnivores die, and the earth is full of frozen corpses. At that time, the scavengers who survived tenaciously will have a very happy time, and they will have endless corpses. However, the corpses will always be eaten on the day they will be eaten, and they will all die."

"Humans shouldn't perish that quickly," Smith asked.
