Among the eight planets of the solar system, if you only look at the appearance, there is no doubt that Venus is the planet that most resembles Earth, known as the "Twin Brothers of Earth".
So if it is a future human being to carry out extraterrestrial migration, is Venus a good choice? Is it suitable for human habitation?
Venus is Earth's close neighbor, with a mass, density, and radius similar to Earth's, but, without a doubt, Venus is not suitable for human habitation.
1, Venus also has an atmosphere, but the main component is carbon dioxide, the concentration is very large, which is completely different from the nitrogen and oxygen needed by life on our earth, and it is difficult to survive alone.
2, the atmospheric pressure of Venus is very strong, about 90 times higher than the Earth, so the surface of Venus is equivalent to 900 meters underwater on the Earth, which is simply unimaginable for humans who have enjoyed standard atmospheric pressure on the surface of the Earth.
3, Venus rotation cycle is too slow, reaching 243 days, longer than its orbital period, such a long time, means that almost equivalent to more than half of the earth's time to pass a day. And the speed is too slow, the temperature difference between day and night is too large, and there is no possibility of survival.
The environment on Venus is really too harsh, and there is a long, suffocating rain of sulfuric acid and so on. Many scientists have imagined that if humans want to immigrate to Venus, they need to transform Venus.
So is it possible that Venus will be transformed?
The conclusion is that in the current human technology, it is impossible, even if there is the ability to transform in the future, there is no need to spend this cost to transform, but the cost of transforming Mars and so on is much smaller.
To modify Venus, it is necessary to modify its orbit, accelerate the rotation period, and change the atmosphere above. Some people want to use asteroids for impacts, so that they reach Mars, Jupiter, and so on, so that the temperature drops, the greenhouse effect is not so heavy, and it may be possible to produce water. Of course, with the current idea, there is no way to complete it directly, unless it is the use of level 2 civilization, that is, the stellar civilization technology, the use of dyson ball ideas.
But obviously there is no point, we want to immigrate, that means that the earth is not suitable for human habitation, but the current environment of the earth is not too bad, human beings have the ability to destroy themselves, but there is no way to destroy the earth, so the earth must be safe and sound.
So that means that the solar system is at fault, and if so, what is the difference between earth and venus?
Therefore, Venus is not suitable for human habitation, whether it is now or in the future, it is impossible to be transformed.
