The origin of the twelve 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 the 2nd century A.D., Ptolemy, an ancient Greek astronomer, synthesized the astronomical achievements at that time and sorted out 48 constellations. Connect the main bright stars in the constellation with imaginary lines, imagine them as images of animals or characters, and give them appropriate names in combination with fairy tales. This is the origin of the constellation name.
