Why is Mercury called Mercury?

Mercury is called mercury because, in the Western Han Dynasty, it was recorded in history books? Sima Qian, the author of Tian Guan Shu, found that it was gray in actual observation, which was related to the theory of five elements. Black belongs to water, hence the name Mercury, and China was called Chen Xing in ancient times.

Mercury, because of its rapid movement, was called Mercury in ancient Europe. In ancient Roman mythology, it means the messenger god running at full speed.

Mercury is the smallest of the eight planets in the solar system and the closest planet to the sun. The orbital period is 87.969 1 day, and it meets the earth once every 6 days, and its revolution speed is much faster than other planets in the solar system.

Mercury is the planet with the largest temperature difference between day and night, and its atmosphere is extremely thin, so it cannot effectively store heat. The temperature in the equatorial region can reach 432°C during the day and drop to-172 C at night.
