What was the name of Mars in ancient China? Why was Mars called a fluorescent star in ancient China?

Mars is one of the eight major planets, and it is the planet that modern scientists focus on. Do you know what Mars was called in ancient China? Why is Mars also called a fluorescent star? Next, let's reveal it in detail by constellation knowledge!

What was the name of Mars in ancient China?

The flicker is Mars. Because Mars is red and shines like fire, its brightness often changes. And in air movement, sometimes from west to east, sometimes from east to west, the situation is complicated and chaotic, so China called it "Ying Ying" in ancient times, which means "Huo Guang, Ying Ying, leaving chaos".

Track inclination: 1.8 degrees.

Earth's equatorial radius: 3398 kilometers

Mass (Earth mass = 1): 0. 1074.

Density: 3.94 g/cm3

Rotation period: 1.026 days.

Number of satellites: 2

Introduction to Mars

Mars is about half the diameter of the earth, with a volume of 15% and a mass of 1 1%. Its surface area is equivalent to the land area of the earth, but its density is much less than that of the other three terrestrial planets (Earth, Venus and Mercury). In terms of radius, mass and surface gravity, Mars is about halfway between the earth and the moon: the diameter of Mars.

About twice as much as the moon and half as much as the earth; Its mass is about 9 times that of the moon and19 of the earth, and its surface gravity is about 2.5 times that of the moon and 2/5 of that of the earth.

Mars is the fourth planet in the solar system from the inside out, belonging to the earth-like planet. Its diameter is about half that of the earth, and it takes twice as long to make a revolution tilted from the axis with a similar rotation period. The West calls it Mars Mythology Star, God of War and China call it Fluorescent Star, because it is as bright as fire, and its position and brightness often change. Its orange-red appearance is because the surface is covered with hematite (iron oxide), and the prefix areo- is Mars in English. Mars is considered to be the most likely planet in the solar system to have extraterrestrial life.

Mars is basically a desert planet, with sand dunes and gravel all over the surface and no stable liquid water body. The atmosphere dominated by carbon dioxide is thin and cold, and dust is suspended in it, and dust storms often occur every year. Compared with the earth, the geological activity is inactive, and most of the surface landforms formed dense craters, volcanoes and canyons in ancient times, including Mount Olympus, the highest peak in the solar system, and Mariner Canyon, the largest canyon.

Another unique topographical feature is the obvious difference between the northern and southern hemispheres: the southern part is an ancient highland covered with craters, while the northern part is a young plain. Both poles of Mars have polar caps mainly composed of water and ice, and the dry ice covered on them will fluctuate with the seasons.
