The origin of constellations

Western constellations originated in Babylon, one of the four ancient civilizations. It is said that the so-called zodiac 12 constellation has more than 20 constellation names, and Mesopotamia was born about 5000 years ago.

Since then, the Babylonians have continued to divide the sky into many regions and put forward new constellations. Around 1000 BC, 30 constellations have been proposed. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table.

In ancient China, Sanyuan, which is near the North Pole, was defined as a middle official, while Erbasu was actually subdivided from four elephants. The star area south of Erbasu was called a foreign official, that is, "middle official+four elephants+foreign officials", which was just one of the many ways to divide the star areas in ancient China.
