Origin in ancient times:
Western constellations originated from ancient Babylon, one of the four ancient civilizations. It is said that the so-called 12 constellations of the zodiac, including more than 20 constellation names, were born in Mesopotamia about 5,000 years ago. After this, the ancient Babylonians continued to divide the sky into many areas and come up with new constellations.
30 constellations were proposed around 1000 BC. Ancient Greek astronomers supplemented and developed the Babylonian constellations and compiled the ancient Greek constellation table. In the 2nd century AD, the ancient Greek astronomer Ptolemy compiled 48 constellations based on the astronomical achievements of the time.
And use imaginary lines to connect the main bright stars in the constellation, imagine them as animals or characters, and give them appropriate names based on myths and stories. This is the origin of the name of the constellation. Most of the 48 constellations in Greek mythology live in the northern sky and north and south of the equator.
