Venus, also known as Taibai, Venus and Aphrodite, is one of the eight planets in the solar system. Why is the surface temperature of Venus so high? How much do we know about it? Interested may wish to know about it!
Why is the surface temperature of Venus so high?
According to scientists' research and observation, the surface temperature of Venus is as high as 465 ℃ ~ 485 ℃. Scientists have finally solved the mystery of the high temperature of Venus after using space probes to conduct many on-site investigations on the atmosphere and the surface of the sphere on the surface of Venus. It turns out that 97% of the atmosphere of Venus is carbon dioxide, and the content of carbon dioxide close to the surface of Venus can even reach 99%. Such a high content of carbon dioxide is like a big quilt covering the surface of Venus. The temperature generated by sunlight on the surface of Venus cannot be emitted, but the temperature is higher and higher. Under the influence of this super "greenhouse effect", Venus finally reached such a high temperature.
Venus is all over volcanoes
Venus is full of volcanoes. It is the planet with the largest number of volcanoes in the solar system. Some scientists estimate that there are even more than 1 million small volcanoes on Venus. These volcanoes have different shapes and varieties. So far, scientists have not found active volcanoes on Mars. Although most volcanoes have been extinguished, we still do not rule out the possibility of their reactivation.
The sun on Venus rises in the West
Many people don't know why the sun on Venus rises in the West and sets in the East. In fact, this problem is easy to explain. Let's take a look at why the sun rises in the East and sets in the West from the earth.
The rotation direction of the earth is from west to East. The East can see the sun earlier than the West. The law of the earth's rotation makes all objects on the earth experience the alternation of day and night every day. The East sees the sun earlier and goes into darkness earlier. So our feeling on earth is that the sun rises in the East and sets in the West.
Venus rotates in the opposite direction of the earth, from east to west, so the sun on Venus rises in the West and sets in the East. The reverse rotation of Venus is probably the result of the collision between Venus and other asteroids a long time ago. If we stand above the northern part of the sun to observe the solar system, we will find that all planets around the sun rotate counterclockwise from west to East, and only Venus rotates clockwise. For the whole solar system, this is undoubtedly a retrograde rotation.
In addition to the reverse rotation, Venus is also very unusual. That is, the rotation cycle and orbit of Venus are synchronous. When the two planets are at the closest distance, Venus always faces the earth with the same face.
Traveling to Venus is fraught with difficulties
So far, there are still many difficulties to overcome if you want to travel to Venus.
The surface temperature of Venus is even higher than that of mercury, which is closer to the sun, and even exceeds 460 ℃. How to resist such a high temperature is a very difficult problem for human beings. Although human beings can walk on the surface of the moon now, the surface temperature of the moon is only 130 ℃. Because the moon has no protection of the atmosphere, the high temperature is only limited to the surface of the ground. The space suits worn by astronauts in the Apollo moon landing program can use the vacuum environment to sublimate water into steam in a vacuum through a special device called a "sublimator", so as to take away heat. However, the surface temperature of Venus is much higher than that of the moon, and the air pressure is very high, so the equipment on the moon cannot be used on Venus. There is also a very thick sulfuric acid cloud on Venus. The acid in the cloud is very corrosive, which requires that the spacesuit worn by astronauts must have very strong corrosion resistance.
In addition, there is a very severe test, that is, the strong wind. In fact, the wind speed on the surface of Venus is not large, about thousands of meters per hour; But the atmosphere on Venus has a very high density, and the wind will increase the external force on the objects that block its progress; So the surface of Venus is full of strong winds and flying stones. If one day, problems such as high temperature and oxygen are solved by humans, strong winds will also hinder humans from walking on Venus, making it difficult for people to walk.
