Pluto, which was kicked out of the nine planets, is terrible because its atmosphere is very thin, and the air pressure is extremely low, and the temperature reaches MINUS 200 degrees Celsius. In many people's minds, Pluto was kicked out of the nine planets because of its extremely small mass. In fact, this understanding is wrong. There is a scientific theory to kick Pluto out. First of all, if you want to be a planet in the solar system, you must revolve around the sun. Pluto did this, but she didn't remove the small objects in its orbit. We can find them in earth orbit. There will be no small celestial bodies or some small meteorite blocks at all. Pluto's orbit is full of small meteorite blocks, so it will not be included in the eight major planets, just because it is too small to attract those small celestial bodies to form a major planet. Next, I will give you a good explanation of Pluto's terror.

Pluto is terrible because it is very far from the sun and its surface temperature has reached more than 200 degrees below zero. Originally, the distance between the earth and the sun is far enough, but if you look at Pluto, its distance is about 40 times that of the earth and the sun, which means 6 billion kilometers. Because it is too far away, the surface temperature of Pluto is very low, and there can be no human beings. Unless it is some advanced intelligent creatures, it will be directly frozen into ice. The most frightening thing is that 98% of its surface is solid nitrogen.

The terrible thing about Pluto is that it has not only the atmosphere, but also liquid water. This makes many scientists very interested, because where there is water, there may be some kind of creature in it. Even if it is cold, maybe some intelligent creature can adapt to the environment there. After all, water is the source of life, but we humans can't live on it because the temperature is too low.

With current human technology, it may be difficult to explore Pluto. After all, human exploration of Mars is a bit too much now.
