Why is Mercury unfit for human habitation? It's hot during the day and cold at night. It's called mercury, and there is no water.

1. Why Mercury is not suitable for human habitation: Mercury is the smallest of the eight planets in the solar system and the closest to the sun. The distance of Mercury at apohelion is about 1.5 times that of perihelion, and the surface of Mercury is covered with craters. Similar to the moon and other satellites, its geology has been inactive for billions of years. Mercury has a thin atmosphere, and the oxygen that humans can breathe is mainly composed of helium and vaporized sodium, and the temperature difference between day and night of Mercury is very large. During the day, the temperature is extremely high, the highest temperature may reach 427 degrees Celsius, and the night temperature is extremely low, which may reach MINUS 173 degrees Celsius. Humans simply cannot survive in such an environment;

2. Why Mercury is not suitable for human habitation. Reason 2: Mercury is hot during the day and cold at night. It's called mercury, and there is no water. Mercury is called mercury because in the early stage of scientific development, human beings have limited knowledge and don't know how to distinguish planets, so they are named according to Yin-Yang and Five Elements. It has mountains, basins and plains, as well as round mountains. However, because Mercury is very close to the sun, when it faces the sun, the surface temperature is as high as 400 degrees, but it will drop to MINUS 100 degrees at night. So the temperature difference between day and night is very large, which is simply a true portrayal of ice and fire. At the same time, due to the temperature difference, Mercury can't store liquid water, and even if it does, it will evaporate to the nearest place in the Mercury solar system in the universe. Although it is called mercury, its surface temperature is as high as several hundred degrees, which is not suitable for human habitation.

3. Why is Mercury unfit for human habitation? 3. The terrain of Mercury is rugged, with many steep slopes, the highest of which may be three kilometers and the length may reach several hundred kilometers. Some scientists think that Mercury may be a little bigger than it is now, but it has been partially compressed by the gravity of the sun, and its radius has been reduced by about one kilometer. And mercury has a large temperature difference between day and night, and the air is thin, because the outer layer of mercury is thin? There is hardly any atmosphere outside. This exosphere consists of atomic oxygen, sodium, magnesium, hydrogen, helium and other trace minerals. Mercury cannot retain heat from the sun and will experience extreme temperature changes. Of all the planets in the solar system, the sunny side will also receive the strongest solar radiation during the day. Because of its orbital position, these extreme days and nights will last for several months at a time, and human beings can't survive at all.

4. Why is Mercury unfit for human habitation? Reason 4: The temperature on the side of Mercury facing away from the sun will be as high as 427 degrees Celsius, while the lowest temperature on the side facing away from the sun will be as low as minus 173 degrees Celsius. Mercury is the weirdest in the solar system. The distance between mercury and the sun also leads to a short orbital period, slightly less than 88 earth days, and the rotation period is only 58.646 days. This means that the spin orbit of Mercury vibrates to 3:2, that is, Mercury rotates three times around its axis for every two times around the sun. This means that 1 day on Mercury can last for two years. Being close to the sun, Mercury receives the strongest solar radiation of all planets. This means that even with temperature protection, mercury exposure to the sun is fatal;
