Chapter 537 Probably Really Second Earth
arc star.

Dong Chen named the Second Earth Arcstar.

He feels uncomfortable if he doesn't have something to do with "Arc Light" when he names it now.

"Arc Star" sounds so good. It not only swears ownership, but also is easy to remember. The most important thing is that you don't have to think of a name from scratch, which will cause a lot of headaches.

The new galaxies are also called arc galaxies, and the names of the planets from the inside to the outside are called arc 1 star, arc 2 star, arc 3 star..., and then all the way to arc 7 star.

This is Dong Chen's official name. As for the specific name, I haven't thought about it yet. I only named the most conspicuous planet of life, and it is not much different from the overall name...

"Forget it, that's the name. The name is just a code, don't care, don't care."

Dong Chen has always comforted himself like this.

Since the four unmanned detection spacecraft have entered, he has received a lot of news these days, and these news made him more and more excited, but also made him more and more doubtful.

This red giant star has been around for 2320 billion years. It can be said that it is older than the sun, but it has only been a red giant star for less than 20 billion years. It has been around for more than 2000 billion years, but its mass is much smaller than that of the sun, which is understandable.

But for such a long time, the civilization of this galaxy has not developed, which shows how lucky the earth is.

Arcstar is smaller than Earth, its diameter is only 80% of Earth's, and its gravity is about 0.94 times that of Earth's. However, it has two satellites, but compared to Earth's satellites, their size ratio is much normal.

However, they are still very bright in the night sky of arc stars. Although the brightness of a single star is not as bright as that of the moon, when both are in the sky, one is much brighter than the moon, at least 15% brighter.

The two satellites are one big and one small, the smaller orbit is closer, and the orbit is farther, so it looks like the small satellite is larger and the larger satellite is smaller on Arcstar.

They are all tidally locked by the arc star, and they always face the arc star, and they also make the tides on the arc star have different changes from those on the earth, even to the point where the double satellites are on the same side of the arc star, and are on the same side as the arc star When they are in a straight line, there is still a spring tide.

One revolution of the arc star is equivalent to 480 hours on the earth, that is, the arc star is [-] hours a day, and one revolution around the red giant star is equivalent to [-] days on the earth. If calculated according to the time of the arc star , that is, one revolution is [-] arc days.

Its temperature is slightly higher than that of the earth, its humidity is also slightly higher, and its seasonal changes are similar to that of the earth, but its air composition ratio is not suitable for human survival.

Although it is mainly nitrogen and oxygen, its oxygen content has reached 25%. The ammonia and chlorine in the air composition are much higher than that of the earth, and the content of various rare gases is also higher than that of the earth. GG is not far away.

Knowing this information, Dong Chen knew how excellent No. [-]'s proposal was. If he really wanted to wear a space suit when he got there, even if he didn't wear a space suit, then an air filter mask would definitely be indispensable.

That would be too inconvenient, and a mechanical substitute would be better.

What surprised Dong Chen was that the creatures on the arc star, or directly intelligent creatures, turned out to be about the same size and appearance as humans.

In addition to intelligent creatures, the animals and plants on Arcstar are also 70% similar to those on Earth. Although the appearance is not exactly the same, they also have some strange animals and plants that are completely different from Earth, but many things can See the shadows of plants and animals on Earth.

This is a little strange.

The two galaxies are separated by an unknown number of light-years, and they can't see each other at all, and the air composition is so different. How can this intelligent creature be similar?
I can't figure it out for a short time, but Dong Chen suspects that this may be related to the wormhole. Maybe humans and arc people are relatives after three generations, so it is true that arc star is the second earth.

This is called 500 years ago was a... er, 37... [-]... [-] billion years ago was a family.

But don’t worry about this matter, anyway, billions of years have passed, and the past few years are not bad, so he just asked No. [-] to record this problem, and he will deal with this matter carefully when he has time and verified.

After observation, Dong Chen found that the level of civilization development of the Arclight people is not high. It looks a bit like a primitive tribe, and a bit like a slave society, but it is a bit strange. The development stages of each place feel very uneven and a bit chaotic.

Their level of metal smelting seems to be high, and some of the buildings look weird, unlike what they should have at this stage.

Just when Dong Chen was wondering, the 3-star Arc Light gave him the answer.

The Lone Light 3 star is the planet that is closer to the red giant star than the arc star, similar to Mars in the solar system, but the arc star 3 is larger than Mars, and its atmosphere is thicker than Mars.

Although the top has been basically covered by yellow sand, the detection spacecraft still found some architectural relics on it, and there are quite a few of them.

Combining the situation of this galaxy and looking at the expanding red giant star, Dong Chen knew the situation.

It should be that with the expansion of the parent star of this galaxy, the habitable zone of animals in the galaxy moved to the outside, and the planets that were suitable for living in the interior were not suitable for living, and became what they are now.

The planet that was originally outside the habitable zone for animals has come into the habitable zone, and has become a beautiful planet suitable for arc people to live on.

Moreover, Dong Chen also felt that the Arclight people on the Arclight 3 star may not necessarily be the first civilization of this star system, after all, this galaxy has existed for too long.

In theory, and only in theory, if the development model of civilization on the earth side is followed, those with high civilizations would have no idea where the waves have gone to the universe.

The more Dong Chen looked at it, the more he felt that there were many secrets to be discovered in this galaxy, but he was not in a hurry now, since he was the only one who knew about it.

Moreover, the stand-in robot is still being upgraded, its dedicated small unmanned spacecraft is also being built, and the equipment it may use on Arcstar is also being manufactured.

Dong Chen's Black Eagle is also being upgraded. After all, he will take the Black Eagle to the wormhole to absorb energy, and then open his third game world. He has been waiting for this day for a long time.

But to execute this plan, he will have to wander in space for a long time, after all, there are still two planets between the wormhole and the earth.

Even if the energy concentration can be recharged in advance halfway, it will still take 20 days to start. It is impossible not to change the cargo warehouse of the Black Hawk into a living cabin.

Therefore, it is still necessary to get things done on the earth side first, and there are a lot of things on the earth these days.

A few days passed, and the time came to June 2020. Under the super-fast construction speed of Arc Light Group, the complete form of the new Tiangong space station was finally completed.

With a body length of 1000 meters, plus the two gravity simulation cabins with a diameter of 500 meters, its huge body is horizontal in the orbit of the earth, how mighty it looks.

At the overall completion ceremony, Dong Chen, a group of guests and reporters finally stopped standing in space or staying in the plane, but all gathered in the reception hall.

The reception hall belongs to the Arclight Group, and it is also a public area. It has been renovated by the Arclight Group. This is also a viewing spot. One side faces the earth, and the other side can see the moon and space.

To hold a press conference in such a place, the face of the Arclight Group is really in heaven.

Those invited guests are better off, the invitation letter from Arclight Group has been delivered directly, there is nothing to argue about.

It was different for the reporters who were invited here. The Arclight Group sent the invitation letter directly to their company. As for who they sent, the Arclight Group didn’t care. The Arclight Group only reserved seats.
