Why does a bright star always appear in different directions when the sun just sets or rises?

Since ancient times, people can always see a bright star next to the sun in the morning and one night, which is located on the west or east side of the sky and named it Morning Star and Geng Star respectively. However, these two stars have never appeared at the same time. There should be very few people who don't know what's going on now, because their real identity is actually Venus. In ancient China, it was also called Taibai Venus, and it was also the villars of the Roman population.

There was a rumor that the probe of the former Soviet Union found the ruins of the ancient city on Venus, but there is no official information about this news. All the information available shows that there can be no social civilization on Venus. So far, human beings are still the only intelligent life known in the world. Recently, there may be life on Venus, which caused a great sensation. So, let's know what kind of planet Venus is.

Why do people usually see Venus in the morning or at night?

The earth has a sister planet, not Mars, which many people pay attention to, but Venus, which is often the closest planet to the earth. This is because Venus and Earth are two Earth-like planets with little difference in mass and radius. However, since the orbital eccentricity of Venus is only about 0.0068 1 1, the orbit of this planet will be closer to a circle than that of ordinary planets. In fact, people usually see Venus in the morning and evening, and Venus seems to be very close to the sun.

In fact, if we look at the positions of the earth, the sun and Venus, we can easily find that if we regard the position of the earth as the vertex of a triangle, but connect the sun and Venus separately, it is easy to observe that the included angle between them is too small, and 48.5 is the maximum. In short, it is precisely because Venus's orbit is actually in the inner test area of the Earth's orbit, which is why we see Venus at a specific time and in different directions.

Why is there no known life on Venus?

First of all, Venus is a planet without a magnetic field. You know, all life living on the earth, including common animals around us, wild animals in nature and ourselves, can thrive on the earth. The earth's magnetic field plays a great role because it blocks most of the harmful radiation from the sun for us. In fact, the earth's magnetic field has been changing. Some scientists say that this magnetic field will have hundreds of magnetic pole reversals in tens of millions of years, and the latest one should be at some time 700,000 years ago.

Second, although humans have never reached Venus, we have learned through detectors that its surface temperature is as high as several hundred degrees Celsius, and its insignificant magnetic field is difficult to resist the solar wind. So Venus's atmosphere is so unbridled by the solar wind. Although the surface of Venus seems to occupy 70% of the plain area, and the lowlands and highlands are only 65,438+00% and 20% respectively, there are volcanoes everywhere on this planet, and thousands of large volcanoes have been discovered so far. Scientists believe that the total number of all volcanoes on this planet is at least 1 10,000, which is considered to be the planet with the largest number of known volcanoes among all planets in the solar system.

How many years will it take for humans to land on Venus?

It is undeniable that people's understanding of Venus began in the former Soviet Union. Although they failed to send probes to Venus many times at that time, Venus 7 finally succeeded in sending the collected information back to Earth. After that, the interplanetary probe in the United States let people see for the first time what the back of Venus looks like and what are the typical characteristics of Venus' clouds.

As we all know, since Pluto was downgraded from a planet to a dwarf planet, there are eight planets in the solar system where the earth is located. Venus is the second closest planet to the sun, but its average surface temperature is as high as 475℃ not only because it is closer to the sun. The moon manned by human beings more than 50 years ago is only the only satellite on the earth. It may take a long time for humans to land on other planets, especially Venus, where the environment is particularly harsh.

In fact, not only the temperature on Venus is too high, but also corrosive sulfuric acid clouds always exist. Even the atmospheric pressure of this planet is nearly 100 times that of the earth. To put it simply, an environment like Venus, not to mention manned landing, is a spacecraft that specializes in collecting planetary features, and it is difficult to land. Moreover, even if one day humans are really capable of landing on Venus, if there is no definite evidence that there may be life on this planet or other equally important exploration tasks, then I don't think anyone will be willing to venture into this planet.
