What is the most feared celestial body in the solar system? Let me say that all celestial bodies except the earth are terrible, because you cannot survive on any celestial body other than the earth.
There are eight planets in the solar system. The environment on each planet can be said to be different. The solar system has at least 170 satellites and countless asteroids. When humans want to get out of the solar system, they must first explore the planets in the solar system. From the planet closer to the earth, the moon is the first. We know that there is no atmosphere on the moon, so people can’t breathe on it, because the air pressure is too small. And die. In addition, the temperature difference between the moon and the moon is very large. When the sun is shining directly during the day, the surface temperature is more than 100 degrees Celsius. When there is no sunlight at night, the temperature is minus 100 degrees Celsius. Such an environment is unimaginable for human beings.
In addition to the moon, the next step for humans is to explore Mars. The United States intends to land on Mars within 10 years. Of course, the conditions of Mars are relatively good, at least Mars is better than the moon. First of all, although Mars does not have such a strong atmosphere as the Earth, it also has a thin atmosphere, but the main gas is carbon dioxide. In addition, the temperature difference between day and night on Mars is not as large as that on the moon. The average surface temperature is minus 23 °C, and there are ice poles on Mars. Therefore, Mars is the most similar to the Earth in the solar system. Planet.
But the Martian Moon is far from the horror of some planets to be said next. First of all, what I want to say is the planet farthest from the sun, that is, Venus. Why is Venus horrible? Because Venus is very close to the sun, the surface temperature is much higher than that of the Earth. Venus has a dense atmosphere and clouds. In the atmosphere of Venus, carbon dioxide accounts for 97%. So it is conceivable that the greenhouse effect on Venus is very serious. How serious is it? The surface temperature of Venus is as high as 500 degrees Celsius, the atmospheric pressure is about 90 times that of the Earth, and the corrosive acid rain often falls on Venus. This kind of environment is simply hell.
In addition to Venus, Jupiter is also scary. Jupiter is the largest and most massive planet in the solar system. Jupiter is the big brother of the solar system. Its mass is 2.5 times the mass of all other planets. Its radius is about 11 Times, equivalent to 1/10 of the sun. Jupiter is a gas planet. Except for the stone core, it is almost entirely composed of gas. There is a violent storm on Jupiter. The prominent sign of Jupiter is a huge storm on Jupiter. The largest one in the red erythema is larger than the diameter of the Earth. It must be big. Since Jupiter has no physical surface at all, Jupiter can be said to have undergone a transition from a gaseous state to a liquid to solid state from the surface to the inside. Jupiter’s magnetic field strength is 10 times that of the Earth. At a pressure of 10pa, the temperature is 340k. The deeper the temperature is, the higher the temperature is. The temperature at the core is 36000k and the pressure is 3000~4000Gpa. If you fall into Jupiter, it will either be burnt at high temperatures or crushed by high pressure.
