In many movies and novels, there will be a very dark and cold world-the underworld. In Roman stories, the underworld is the residence of the soul and the dead. Pluto is the boss of the underworld, but in the Greeks In the myth, the boss of the underworld is Hades.
In fact, in the solar system, we have also found a planet similar to the underworld. It is Pluto at the extreme edge of the solar system. Because Pluto is very far away from the sun, there is almost no light. It is very dark, and the temperature is extremely low, covered by rocks, which is very similar to the underworld in people's mouth. Scientists say that one year in the underworld is equal to 246 years on Earth.
Pluto was discovered by Clyde Tombaugh in 1930 and identified it as the ninth largest planet in the solar system. Because Pluto is so far and dark, it has been Think of it as the "underworld," and many people also think that the soul will go there when humans die.
Although Pluto has been eliminated from the eight planets of the solar system, scientists also know a lot about Pluto, especially when the US probe "Shinno" reached the orbit of Pluto. At that time, let us have a glimpse of the full picture of Pluto. Scientists found that a year on Pluto is equivalent to more than 90,000 days of the earth, which is 246 years.
Actually, Pluto and the earth also have some similarities, for example, there is a movement of the earth’s core beneath Pluto, and Its cracked surface is in order. Maybe there are many unknown secrets on Pluto, but scientists can’t detect them.
Pluto is also destined to be an unsuitable place for survival. Compared with the earth, the atmosphere of Pluto Very thin. Many people feel regretful. Why is Pluto excluded from the planet? In fact, it’s mainly because there is a Kuiper belt near Pluto. There is a celestial body in the Kuiper belt, the size of which is about the same as Pluto., So scientists identified Pluto as a similar celestial body in the Coipu Belt and excluded him from the ranks of planets.
