Who invented the constellation? How to calculate?

Everyone knows that "constellation" is the culture of western countries, but how did he invent it, how to calculate it, and why is it so popular? Many people are not very clear. Today I will tell you about the calculation process of constellations.

In western history, the constellation was originally just a street lamp extended in ancient times to correctly identify the orientation and observe the weather changes during navigation. By combining the scattered stars in the sky with the imagination of the ancients at that time, they were named according to the myth and shape of ancient civilization respectively. In ancient times, half of the constellations were named, and the other half were named only in modern times. The naming method is the name of commonly used navigation instruments. The connection mode of constellations was unified in 2 1 century.

As we all know, the constellation originated in Babylon, one of the four ancient civilizations, and Cuba lives in the "two river basins" area. Under the impetus of cultural development, the culture of the two river basins spread to ancient Greece. Ancient Greek astronomers supplemented and developed the Babylonian constellation and compiled the ancient Greek constellation table. After the Middle Ages, European capitalism rose and needed to expand outward. The origin of constellations has greatly developed European navigation, and stars have become the best street lamps for maritime navigation.

His calculation process takes the sun as the observation center, which is called the ecliptic, and then divides the ecliptic into twelve sections, and divides the spring into zero, that is, the ecliptic is zero, and every 30 degrees is a palace, followed by Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces, which is called the zodiac.
