There were no astronomical telescopes in ancient China, so why could the five planets be appropriately named after the five elements?

Because the five stars are the five planets that ancient Chinese observed with the naked eye very early. Therefore, more people think that people in ancient times may have named them according to Yin Yang and Five Elements, so that they can be trusted. These five planets were originally called Chenxing, Taibai, Yinghuo, Suixing, and Zhenxing (or filling stars). Later, these planets were named according to the concept of five elements. They were correspondingly called Mercury, Venus, Mars, Jupiter, and Saturn in order. They are arranged from nearest to far from the sun.

In ancient China, astronomers existed for a long time, but they did not use this title. People at that time always liked to observe the sky at night and look at the stars in the sky. Over time, , he himself summed up some rules. Of the eight major planets in the solar system discovered now, there are five planets that humans can observe with the naked eye. They are the well-known five elements, metal, wood, water, fire, and earth. In ancient times, people continued He didn't even know there was a planet beneath his feet.

In fact, the ancients were able to observe these stars, but they did not know much about them. They just thought that if they moved, they might mean something. Therefore, in history, many emperors would set up an official position specifically for Find some people who understand astronomical phenomena, just look at the sky every night. If you find the movement of the stars, it will indicate something, so you can prepare in advance.

Due to limited observation methods, the ancients did not discover Uranus, Neptune and Pluto. Since there has been controversy over whether Pluto is a planet in the solar system, I heard that a conclusion has now been reached and Pluto has been expelled from the planets, so that there are eight planets in the solar system.
