If you look at the sun on the earth, it looks like a small hot disk at noon, then it looks like an enlarged version of duck egg yolk in the morning and evening, then it looks like the sun on the Mercury closest to the sun. What does it look like?

You can hear it from Lei Tiantang's pretending emotion now. Because the distance between Mercury and the sun is the closest in the entire solar system, the sun on Mercury will of course be much larger than on the earth. Kuafu Tucao is not wrong at all.

In fact, the size of the sun on other planets is inversely proportional to the distance between the planets and the sun. The earth is 1 AU from the sun, and Mercury is 0.387 AU from the sun.

Then the size of the sun when viewed on Mercury is 1/0.378=2.645 times that of the Earth. If you calculate the number of pi, you will get 8.31 times the number. Therefore, when you look at the sun on Mercury, you should look at the sun on the earth. 8 times more points.

But because Mercury has no atmosphere, it will not scatter sunlight. Therefore, although the sun is very large and the sunlight is very strong on Mercury, it does not have an atmosphere and will not scatter and refract sunlight. The sky on Mercury still looks dark, just like the color of the earth’s night sky. You can see the stars.

So the pretending remarks behind Lei Tiantang are still nonsense. It would be a **** to see the stars facing such a big sun!

Although the company has also put two probes into the orbit of Mercury, Lei Tiantang and the others put a large number of probes in the solar system during their last voyage to Mars, and of course there are also Mercury here.

A total of 12 probes that flew to Mercury finally, 9 of them successfully entered the orbit of Mercury. Both Lei Tiantang and Kuafu are very satisfied with this success rate. If they really enter the orbit of Mercury 100% It would feel strange.

Thousands of large-scale detectors Lei Tiantang and their psychological expectations are 80%. As long as 80% of the detectors can successfully complete their missions, they will be satisfied, even if the environment inside the solar system is still safe, but This does not mean that it is not dangerous at all.

All kinds of tiny space debris, the gravity of the sun and other planets, the failure of the probe itself, and other factors will cause the loss of the probe. It is really good to have 9 into the orbit of Mercury.

There are a total of 10 satellites to provide Lei Tiantang with detailed data, and they don’t need to come here to detect Mercury data. After all, Mercury is so small in size, even more famous than Ganymede and Titan. The Titans are even smaller.

What if its mass is greater than them? The speed and efficiency of the detector's detection depend on its volume, not its mass, so the data provided by these 10 satellites is sufficient for Lei Tiantang to determine the location of the base before coming here.

After all, they only plan to build an outpost on Mercury, and there is no need to entangle the issue of site selection, and as long as they don’t want to die on Mercury, they have to choose places that are relatively risky. There is no problem anywhere else, anyway. What they built was just an underground base.

The underground environment of Mercury is much better than that of Mars and Venus. Don't look at people small, but they have a solid body! Why is Mercury so massive? That's because people are made of about 70% metal and 30% silicate materials!

The density of Mercury is 5.427 g/cm??, which is the second highest in the solar system, after the earth's 5.515 g/cm??. If the effect of gravitational compression on the density of matter is not considered, the density of Mercury’s matter will be the highest—the density of Mercury’s matter without gravitational compression is 5.3 grams/cm??, compared to the lower Earth’s matter at 4.4 grams/cm? ?.

From the density of Mercury, we can infer the details of its internal structure. The high density of the earth, especially the high density of the core, is caused by gravitational compression, and Mercury is so small that its interior will not be strongly squeezed.

Therefore, if it has such a high density, its core must be very large. The mass of its inner core can even account for 2/3 of its total mass. In contrast, the mass of the inner core of the earth only accounts for 1/3 of the total mass of the earth.

The main components of this nuclear ball are iron, nickel, and silicate. According to this structure, based on the data detected by the probe, the iron content of the entire Mercury may reach two trillion tons. If the entire planet produces steel, Based on the annual output (about 800 million tons), it can be mined for 240 billion years.

Of course, Lei Tiantang himself and Kuafu do not look down on these metal resources. The various materials left by the body of the small black hole swallowing the star system are more than 10 times more than this, and they can all be used at any time. Under the circumstances, of course they will not exploit the metal resources here on a large scale.

However, after the construction of the underground base is completed, if Kuafu is boring, he can mine some by himself, otherwise the energy of a nuclear fusion reactor is only used to maintain the normal operation of a base, which is a bit wasteful.

And even without considering its metal core, the crust that can be retained at such a close distance as the sun is not strong enough, it must have been evaporated by the sun a long time ago.

This is also the reason why Lei Tiantang and the others directly landed toward the selected position as soon as they entered the orbit of Mercury. Although the temperature rise on the surface of the spacecraft will not cause any damage to the spacecraft, but it is so far away from the sun. Lei Tiantang still didn't want to stay too long nearby.

Because after seeing it, he would easily calculate in his mind how much his ability would increase if he swallowed it~lightnovelpub.net~ What a terrible thing!

You must know that he is a native of the earth. He only appeared on this star. The entire human beings on the earth cannot do without this star of life, so even if he could not help flashing these data in his heart , He was not so frantic enough to destroy the sun to bring himself one of the few ability improvements.

In order to get rid of the influence of these distracting thoughts, Lei Tiantang decided to finish early and finish early, so he successfully left his footprints on Mercury and retained the evidence of his success in clocking in, so he started directly with a positive attitude towards work. That won't work!

Since there is no need to build a cumbersome thing like a collider at this base of Mercury, the construction of the entire underground base is not too simple for Lei Tiantang and Kuafu, who are already proficient in business. It only takes a day. At that time, the construction was completed successfully.

Even the channels and processing space for mining and smelting ore are ready for Kuafuxian's boring time, so I can take this opportunity to test the long-term self-sustaining ability of the underground base without supply.
