Who is the blood clan in the zodiac?

In the three-dimensional universe, there is no necessary connection between these stars. Their positions on the celestial sphere are similar, but in fact they may be far apart.

If humans were in another solar system of the Milky Way, they would see the starry sky completely differently. Since ancient times, people have been interested in the arrangement and shape of stars, and naturally linked some stars with similar positions to form constellations.

The origin of constellations

Mesopotamian astrologers divided the starry sky into several regions for the convenience of studying and observing many stars in the sky, and each region was a constellation. It is difficult to say exactly when humans began to have the concept of constellations. This astronomical knowledge was known long before there was a historical record, and the name of the constellation probably came from the sailors who sailed early.

The origin of constellations may be completely different between civilizations in different regions, but with the expansion and mutual influence of civilizations, the culture of constellations also includes the process of integration.
