What is the common name of the Milky Way?

The common name for the Milky Way in ancient my country was Tianhe. The English name of the Milky Way: The Milky Way The Milky Way is a giant barred spiral galaxy (a type of spiral galaxy), Sb type, with 4 spiral arms. Contains 120 billion stars. The Milky Way as a whole rotates poorly. The rotation speed at the sun is about 220 kilometers/second, and the sun orbits the center of the galaxy for about 250 million years. The visual absolute magnitude of the Milky Way is -20.5. The total mass of the Milky Way is about 1.4 trillion times the mass of our sun, which is roughly 10 times the total mass of all stars in the Milky Way. Extended information The discovery and names of the eight planets in the solar system 1. Mercury Mercury always appears near the sun. When viewed from the earth, its angular distance from the sun is no more than one chen. In ancient times, a week was divided into 12 chen. Therefore, in ancient China, Mercury was called "Chenxing". Mercury sometimes appears at dawn and sometimes at dusk, causing ancient people to think it was two different stars. The early Greeks called Mercury "Mercury" when they saw it in the mist, and "Apollo" when they saw it in the early morning. Ancient Indians called Mercury "Lolinaya" and "Buddha". The ancient Egyptians called Mercury the Set of Herus, and the Buddha was the two guardians of the sun god. 2. Venus In ancient China, people called Venus "Taibai". When it appeared in the morning, people called it "Morning Star", which means that the east is dawning and opening up the light. When it appears at night, it is also called "Chang Geng", which means that twilight is falling and the long night is approaching. Now, the whole world calls Venus Venus, the name of the goddess of love in Roman mythology. The beauty of Venus, the goddess of love, matches the crystal clearness of Venus very well. It is called Venus because some people believe that it is composed of gold and silver. Astronomical surveys in recent years have shown that Venus is indeed rich in mineral deposits. 3. Earth Earth was based on the Indo-European language family and gave rise to the Germanic noun "Ertho". Eventually, Germany, the Netherlands, Scandinavia and the British all called the earth the earth or land. People once called it "Pangaea", and there was also a "Pangaea", that is, the ancient Pacific Ocean. 180 million years ago, Pangea separated and gradually drifted, forming five continents and four oceans. . 4. Mars Mars is the brightest star that people can see with the naked eye. Because the dark red color of Mars makes people imagine that it symbolizes the iron and blood of war, so Westerners call Mars Mars. Mars is the name of the god of war in Greek mythology. In astronomy, the representative symbol of activity is a spear. In ancient China, Mars was called "Yinghuo" because Mars is red and glowing like fire, and its brightness changes frequently and its whereabouts are unpredictable, which is confusing. 5. Jupiter is in the west. Jupiter is considered to be the incarnation of Cupid, the god of love in mythology. In ancient China, it was called the "year star" because people used it to determine the age. It orbits the sun for exactly 12 years, which is consistent with the heavenly stems and earthly branches. The chronology matches. Jupiter is a planet with extremely large size and mass. Its volume is more than 1,300 times that of the Earth, and its mass is 2.5 times that of the other planets combined. 6. Saturn When ancient Westerners saw the slow movement of Saturn, they thought it symbolized the passage of time and changes in fate, so they named it after the god Satum in Roman mythology, symbolizing that the passage of time would not bring harm to people. come any good. The symbol of Saturn is a scythe, which symbolizes both time and agriculture. In ancient China, people believed that Saturn moved once every 28 years, as if it "sited in one of the 28 constellations" every year, so they called it the "presence star." 7. Uranus In 1781, the Englishman William Herschel discovered a new planet in the solar system. He wanted to call it "George's Planet" to repay King George III for his support and funding. Some astronomers advocate naming the new planet "Herschel" to show respect for the discoverer. However, both proposals were rejected. People adopted the suggestion of Bode, director of the Berlin Observatory, and followed the tradition of naming planets after mythological figures. They named it after the god Uranus, which is translated into Chinese as Uranus. The Uranus symbol is marked with the letter "H", which is the first letter of the name of its discoverer Herschel.

8. Neptune Neptune is the eighth planet farthest from the sun. It was discovered on September 23, 1846 through its perturbation of the orbit of Uranus. The earliest calculator was Adams, a college student at the University of Cambridge in the United Kingdom. The German astronomer Galle first observed Neptune on September 23, 1846. It appeared very close to Adams and Le Verrier. Based on the observed positions of Jupiter, Saturn and Uranus, it was independently predicted through calculations. Out location. He was the first person to observe the planet from its calculated position. The discovery was seen as an example of the accuracy of the theory of planetary motion. Neptune is dim because of its distance. An international dispute arose between Britain and France over who discovered Neptune first and who had the right to name it. However, there was no apparent personal dispute between Adams and Le Verrier; now the discovery of Neptune* **Important credit goes to both of them. Later observations showed that the orbit calculated by Adams and Le Verrier deviated considerably from Neptune's true orbit. Had the search for Neptune been carried out a few years earlier or later, people would not have been able to find it at or near where they predicted it would be.
