Twelve constellations in the eyes of scientists:

Among all kinds of astrology, the most popular one is the "Twelve Constellations", which, in the eyes of astronomers, is only based on the names of constellations intersecting with the ecliptic.

Because the earth revolves around the sun, when people look at the sun from the earth's mobile platform, it is the sun that revolves around the earth relatively-the sun moves slowly on the starry background, only once a year, and returns to its original position. The route that the sun "walks" in this way is called the ecliptic.

Moreover, the orbit of the moon around the earth, that is, the "white road", and the orbit of planets around the sun is very close to the ecliptic, so the moon and planets always "shuttle" back and forth not far from the ecliptic, so that the ecliptic region has become a "runway" for celestial bodies such as the sun, the moon and the planets to chase and meet each other.

Babylonians paid special attention to this phenomenon more than 3000 years ago, so they drew a wide road along the ecliptic-the so-called "Zodiac Belt", whose width extended to 8 degrees on both sides of the ecliptic, *** 16 degrees. The zodiac signs were first marked by the zodiac signs, with an average score of 12, which is called "zodiac signs".
