The Moon is a satellite of the Earth, and in the solar system, in addition to the Earth, Mars and Venus are also in the habitable zone, but only life has formed on Earth, and it can only be said that the conditions for the formation of life are too harsh, and one of the many conditions cannot be formed.
In the nineteenth century, astronomers found in the telescope that there are canal-like lines on Mars, so the theory about Martians became popular, and it was later confirmed that these are not real canals, but the pace of human search for aliens has not stopped, so far human beings have explored all the extraterrestrial planets in the solar system, and have not found the existence of extraterrestrial life.
According to the form of life on Earth, scientists propose that in order for life to evolve on a planet, many requirements need to be met, first of all, the planet must be in a habitable zone to ensure that water can exist in liquid form most of the time, if it is too far away from the parent star, then the water will freeze for a long time, and if it is too close to the parent star, the water will completely evaporate.
The position of the earth in the solar system is optimal, the average surface temperature is about 14, and there is an ocean of liquid water, in addition to Mars and Venus are on the edge of the habitable zone, human probes have also landed on these two planets, of which the surface temperature of Venus is as high as 450 all year round, and the average temperature of the surface of Mars is -50, and no life has been found.
The only extraterrestrial planet that humans have landed on is the moon, as a satellite of the earth, although it is also in the habitable zone of the solar system, but the surface conditions of the moon are very poor, which is not conducive to the survival of life at all, such as:
1) No atmosphere.
The gravitational pull of the Moon is only one-sixth of that of the Earth, plus the Moon itself has no magnetic field, and the strong solar wind can reach the surface of the Moon, so the Moon cannot bind the atmosphere, and the surface is in a high vacuum.
2) The temperature difference between day and night is large.
The moon revolves around the earth, the orbital period is about 27 days, because the earth is also revolving around the sun, so the moon phase change cycle is about 29 days, that is to say, a day and night cycle on the moon is as long as 29 days, which makes the temperature difference between day and night on the surface of the moon very large, the maximum temperature during the day is as high as 120, and the night is as low as -200.
With these two extreme conditions, the probability of life on the moon is basically zero, and there is also a possibility that when other asteroids hit the earth, the earth's material will be knocked out, and it is possible to spill life on other planets.
Some people may have questions, the temperature difference between day and night on the moon is so large, how did the American astronauts land on the surface of the moon in the first place, if you check the time of the six manned moon landings, you will find that the moon landing time is between the sixth and the tenth of the lunar calendar, that is, it completely avoids the highest temperature during the day and the night when the temperature is extremely low.
-
Being in the habitable zone is just not easy to be hit by asteroids, and there are many living conditions, such as water, air, etc., which are not available on Venus and Mars.
-
The temperature of their surface varies greatly, the atmosphere is very rich in toxic gases, and their autobiographies and revolutions are relatively long, which makes it difficult for organisms to survive on them.
-
Because although Venus and Mars are in the habitable zone, the environment on these two planets is too harsh and unsuitable for survival.
-
Venus. Mercury, are close to the sun, not in the habitable zone of the solar system, Mars, earth, wood, Neptune, Pluto, these galaxies are too far away from the sun, let alone in the habitable zone of the solar system, at present, only the earth in the solar system is in the habitable zone, the earth is a living planet, with a magnetic atmosphere, liquid water, oxygen, <>
And it is just right, if Venus, Mercury, and Mars are moved to the current location of the earth, the missing ones are suitable for life to survive, because Venus, Mars, and Mercury are all dead planets. The Moon is also in the habitable zone of the solar system, so why is there no life on the Moon? Because each moon has no magnetic field, no atmosphere, and a dead planet, it can become a habitable planet, suitable for life, and the conditions are difficult for other planets to achieve.
Venus, which the German Hans has already investigated, has proved with facts that it is still not suitable for human habitation, let alone for human life and reproduction.
In fact, the habitable zone of the solar system is a very wide range, and it does not only refer to the area where the earth is located, our earth is only in the middle of the habitable zone, that is, a very perfect position. And the planets located in the habitable zone are not only our earth, but also the moon, Venus and Mars are located in the habitable zone, but Venus and Mars are located on the edge of the habitable zone.
But don't think that as long as the planet is located in the habitable zone, it must be suitable for human survival, look at our Moon, which is located in the ** region of the habitable zone like the Earth, but the Moon is not suitable for human survival at all, and the same is true for Venus and Mars. What does this mean? It shows that "being located in the habitable zone" is only the most basic condition suitable for human survival, and there are many other conditions that restrict whether a planet is suitable for human survival.
Humans, animals and plants are the internal elements of the earth, the tools used by the earth to regulate its own dynamic equilibrium in the solar system, or the components and elements of the earth to regulate its own balance and dynamic operation, which can only be unique to the earth. Human beings will lose their role if they leave the earth, so there is no need for human beings to exist, and of course they will be eliminated by the solar system.
Of course, there must also be an Earth in another solar system. For the solar system to maintain its own dynamic equilibrium in the Milky Way, its components are unchanged, and the existence of the Earth is required.
-
Venus and Mars are more habitable than the earth, why there is no life on them, whether a planet has life or not depends not on its habitability, but on its various factors, the temperature is suitable, water, soil and other natural resources are complete, so that life can be born and can be inhabited.
-
This is because the environment above Venus and Mars is very harsh, and there is no attraction on the ground, so it is not suitable for human survival, and the air above is very thin, and it also needs to provide very sufficient oxygen to survive normally, so there is no life on it.
-
Mainly because these two planets are either short of water or oxygen, so there is no life.
-
In all respects, Venus is indeed similar to the Earth in many places, it is the closest terrestrial planet to the Earth, and because its mass is similar to that of the Earth, it is also called the "sister star" of the Earth's Wheel Change. Venus, Earth, and Mars are all located in the habitable zone of the solar system, but in the end, only Earth evolved life. Whether the formation of Venus's atmosphere means that humans can move to Venus is obviously not absolute, Mars also has an atmosphere, but the current Mars is not suitable for human migration.
Of course, proof is needed to show that Venus is not suitable for human migration.
The atmosphere on Venus is mainly carbon dioxide, and secondly, it also contains a small amount of nitrogen. In addition, the atmospheric pressure on Venus is very large, equivalent to 92 times the atmospheric pressure of the Earth, which is equivalent to the pressure at a depth of a thousand meters in the ocean, and most things are deflated under this pressure.
In fact, the United States and the Soviet Union once explored Venus, because the pressure on Venus was too great, and the lander was directly crushed in the process of descent and lost contact. Can humans survive at this atmospheric pressure? Pressed alive into a piece of bread.
Secondly, on the top of Venus, due to the large amount of carbon dioxide, the greenhouse effect on Venus is very serious, and the maximum temperature can reach 500 degrees Celsius, which is not suitable for migration.
Let's talk about the surface of Mars, there are countless volcanoes on the surface of Mars, more than 1,600 large volcanoes have been discovered, and countless small volcanoes are estimated to be millions together. In addition, there is no moisture on the surface of Mars, and the main component of Venus's clouds is sulfuric acid, in which it is obviously difficult to even land a lander, let alone move on a large scale.
Speaking of moving to other planets, Venus is more impossible than Mars, Mars is easier to transform than Venus, and it is still possible for humans to stay on it for a short time with the help of special aids, Venus is absolutely impossible, it is difficult to even enter Venus, and Venus is a hellish world above it!
-
Not at all, the environment of the Jin Shen satellite is extremely harsh, and it is very difficult to even launch a probe to land and investigate; Venus is too close to the Sun, and the solar radiation is too strong for humans to bear; Venus's self-equilibrium rotation cycle is 243 days, either too cold on one side or too hot on the other; The rain above and below Venus is sulfuric acid rain, and no living thing can survive. Finally, Venus has no magnetic field, and without a magnetic field, it is easily attacked by the solar wind.
-
No, because the living environment of Venus is still far from the earth, and the technology has not yet reached the step of migration, so it cannot be moved.
-
Humans can't move to Venus, because the planet Venus is not suitable for human life, and the environment here is really poor.
-
No, because the environment of Venus is not suitable for human survival and is not suitable for growing plants.
-
With the advancement of science and technology, mankind has become more active in aerospace.
The realm is developing rapidly, and moving to other planets is a goal that humanity strives for. Nowadays, people are paying more attention to Mars, hoping to move to Mars one day. Why did humanity abandon the near future and go to Mars instead of landing on Venus?
Compared with Mars, it only takes 100 days for humans to reach Venus from Earth, and it will take more than half a year to reach Mars at the earliest. Moreover, Venus is known as the sister planet of the Earth, and its mass and volume are about the same as that of the Earth. Venus also has an atmosphere.
Why don't humans choose to live on Venus?
There's a reason for that. After so many years of research and exploration, it was found that although Venus is very close to the Earth, its living environment is quite harsh. First, let's take a look at the temperature on Venus.
The temperature of Venus can reach 480 degrees throughout the year. The orbit of Venus is almost circular and almost not tilted. So there will be no four seasons, day and night, and the temperature of the entire surface will be almost the same.
We can't stand the heat on Venus. For humans, such a high-temperature environment.
Not suitable for human survival. In addition to high temperature conditions.
Venus is not suitable for human survival. The second condition is the atmosphere. Carbon dioxide in the atmosphere of Venus.
The concentration is above 98%. Don't say any of that. After all, outside of Earth, humans have not found any oxygen on any planet.
Such a strong atmosphere. The surface pressure of Venus is about 90 times that of Earth. It's like we have 2,000 people on our chests.
Who can withstand this pressure?
In addition to high temperature and high pressure, Venus's harsh environment also includes wind speeds of several hundred meters per second, and the sulfuric acid on the surface of Venus will be blown by strong winds.
It forms a thick layer of sulfuric acid mist. In addition, Venus has thick clouds that reflect 90% of the sun's rays, so the surface is dark and the visibility is visible.
Approximately kilometers. It is difficult for such a person to survive on it. Secondly, there is acid rain every day.
Falling on Venus, these highly corrosive substances are not suitable for human survival. The last day on Venus corresponds to the year of Earth time. So a lot of factors suggest that we are not fit to live on Venus.
Mars may be a better option. After the transformation of Mars, there may be the possibility of human migration, but the natural conditions of Venus are there, and human beings cannot be transformed. Not to mention that Venus has no research value. Scientists have discovered that Venus's upper atmosphere is full of ultraviolet rays that can absorb it.
particles, but no one knows what these particles are. If humans can find out, it may contribute to a breakthrough in UV protection research.
-
Based on the current exploration results, is Venus suitable for human habitation? I don't think it's suitable for human habitation. Venus, as Earth's closest neighbor planet, has always been considered Earth's "sister planet".
Its radius is only 400 kilometers smaller than that of Earth, its average density is Earth's, its volume is times that of Earth, and there is also an atmosphere and clouds around Venus.
-
Unhappy. According to the current detection results, the environment above Venus is very harsh and the oxygen content is very low, so it is not suitable for human habitation.
-
It is uninhabitable for human habitation because Venus does not have enough water and does not have oxygen, making it unsuitable for human habitation.
-
Water is being generated on the surface of Venus, creating an atmosphere needed for life, which tends to be covered by water, and organic matter has begun to form in the surface space of Venus. The temperature of the sun is 140, because there are many solidified impurities in the space, the temperature rises close to 400, and the temperature below 10m underground is only 2, and the temperature in the temperature-proof building can be reduced to about 20, and the stratum is suitable for the survival of life. The temperature-proof building floor can be cultivated, and there is a water source in the valley, and the water source is increasing, and there is no shortage of water.
In the future, high-rise buildings can be built when they are covered by water, and life can be more easily sustained. Venus is moving away from the Sun at a rate of 30 meters per year, and it is the closest migratory planet to Earth humans, and it is the migratory planet where life is saved.
Venus is located at the inner edge of the habitable zone of the solar system, slightly smaller in diameter than Earth, but the surface environment is too harsh for human habitation. In the early days of the formation of the solar system, the environment of the Earth and Venus was very similar, but the emergence of early organisms such as cyanobacteria on the Earth improved the Earth's atmospheric environment and controlled the atmospheric carbon content within a certain level; The situation on Venus is completely reversed, with carbon dioxide levels completely out of control, and the current carbon dioxide content is as high as 96%, triggering a global greenhouse effect.
When the sun's rays reach the surface of Venus, the heat is stored in the atmosphere, and the average temperature on the surface of Venus is now as high as 460, which is enough to melt metallic lead, the pressure is up to 90 atmospheres, and the sky is full of strong acid rain. Several Soviet probes landed on the surface of Venus, but they were completely destroyed shortly after their operation. The most important chemical element for life is water, and in the conditions of the surface of Venus, water has become supercritical, and its chemical properties have become very active, and it is impossible to help life at all.
With the current level of human technology, it is simply impossible to improve the atmospheric environment of a planet, but on an extraterrestrial planet like Mars, human beings have the ability to build Mars bases, establish human settlements in a small area, and gradually realize interstellar migration, and the United States also has such a Mars plan in this century.
At present, the Nebula theory is the dominant view. For more information, please refer to the encyclopedia.
After studying the asteroid Cleopatra, astronomers determined that the asteroid was a unique object in the solar system. >>>More
The solar system consists of eight planets and their moons and more than 6,000 asteroid belts.
Yes, because the earth has an atmosphere, the temperature can generally be considered to be around 20, while the moon has no atmosphere, and the temperature can reach more than 100 degrees on the side facing the sun, and about -270 on the side facing the sun. So the temperature difference between the Earth and the Moon is huge. Other planets are either very far from the Sun, and the planets and their moons are very cool, like Jupiter and Saturn. >>>More
The planet is out of the gravitational range of the star in its motion around the star. Taking the solar system as an example, planetary escape means that all eight planets have left the solar system, and the fundamental reason is that the gravitational pull of the stars becomes smaller, and the planets cannot be restrained from continuing to move in their original orbits.
