What would it be like if humans immigrated to Earth-like planets?

In the last article, I shared with my friends that the eight planets in the solar system are divided into two categories, wood-like planets and earth-like planets. Wood-like planets are mainly gas, rocks and land, which are not suitable for human survival.

So what kind of environment would it be if you moved to a terrestrial planet outside the earth?

I will continue to share it with my friends.

I believe that when friends watch TV dramas about myths, they often hear the phrase "a day in heaven has passed for a year". So, "where is the prototype of heaven?" In fact, I think the mythical "heaven" is actually Venus. Because Venus rotates from east to west, it is called "reverse rotation" by human beings. So on Venus, the sun rises in the west and sets in the east. In addition, Venus rotates very slowly. A day and night on Venus is about 1 17 days on Earth, and a year on Venus is only twice as long as that on Venus.

Venus has many similarities with the earth.

There is also a thick atmosphere outside Venus. Venus has a radius of 6,070 kilometers, which is 95% of the Earth's, and its mass is 82% of the Earth's, and even its average density is only 5% lower than the Earth's. With so many similar places, friends should also think that human beings can immigrate to Venus in space in the future!

Can we humans live on it?

But Venus is also like a pressure cooker. Its thick atmosphere can continuously receive sunlight, but heat cannot be emitted from the atmosphere. On the other hand, the high-density atmosphere has caused extremely high air pressure, so Venus is like a pressure cooker, constantly receiving heat and getting hotter and hotter. If we humans live on Venus, it will be melted soon.

Why are the days on Mercury like years? First of all, the rotation speed of Mercury is relatively slow, and one day here is equivalent to 59 days on Earth. Because mercury is close to the sun, it takes the shortest time to circle the sun among the eight planets, only 88 days, and it ends in less than three months a year. A day on Mercury is two thirds of a year.

What is the environment on the surface of Mercury?

First of all, Mercury is close to the sun, so the sun seen on Mercury is six times larger than that seen on Earth, and the radius of Mercury is only 38% of that of the Earth, its mass is only 5.5% of that of the Earth, and its gravity is only 37% of that of the Earth. The surface of mercury is very similar to the moon, but it is even more rugged than the surface of the moon. Mercury is covered with craters, as well as plains, rifts, basins and other landforms, among which Calorie Basin with a radius of 1300 km is the place with the highest surface temperature in planets of the solar system. It almost reaches 634.5℃, and the lowest temperature is-173℃.

Is there a lot of water on Mercury?

Mercury was named because ancient China people named the planet according to the "five elements" (water, fire and earth in Jin Mu). There is no air on the surface of Mercury, so there is no water on Mercury. If human beings live on mercury, they will first die because of temperature difference, water shortage and air.

Speaking of Mars, friends feel familiar with it, because almost every year, developed countries in the world launch satellites and robots to explore the environment of Mars and study whether it is suitable for human habitation.

Although Mars is much smaller than the Earth with an equatorial radius of only 3,398 kilometers, it is similar to the Earth in many places. First of all, it also revolves around the sun with a curved body like the earth, and its day and night time is only more than half an hour longer than the earth. There are also four distinct seasons in a year, and the temperature in some places is close to the earth.

Traces of river beds and water sources on Mars.

Moreover, in recent years, it has been reported that there were traces of liquid water rivers on Mars, which is one of the important conditions inseparable from human living environment.

But water is invisible and intangible. Scientists found that it was frozen, locked in water-rich minerals and hidden below the surface, which is why we still don't know where it is.

However, some scientists believe that Mars can't carry out plate movements like the earth, and it can't have atmospheric circulation like the earth, which leads to its extremely low temperature and it is extremely difficult for life to exist in such an environment.

Due to various conditions, scientists' research on the universe is still limited, including the study of the solar system and other planets in the Milky Way. But I believe that with the continuous progress of science and technology and the unremitting efforts of scientists, we humans will know more and more about the universe, and space migration will certainly be realized in the near future.

Friends, are you looking forward to this day? You can talk about your own ideas!
