Did the twelve constellations really become thirteen constellations?

In fact, the thirteen constellations have existed for a long time and have been used for a long time, but they have not been accepted by the broad masses of the people. From the astronomical point of view, the earth's orbit around the sun is fixed, and unless there is a very small probability event, the ecliptic will always be almost the same as today.

By the same token, if the position of the constant star has not changed at all, and the division of constellations has not been misinterpreted, there will always be thirteen constellations on the ecliptic, in addition to the constellation corresponding to the ecliptic, plus Ophiuchus. But in science, the position of the star is not fixed, it will move, which is called "self-motion" in astronomy.

Although the value is very small, after years of accumulation, the layout of astronomical phenomena will change greatly. When the thirteen constellations officially began to be widely used depends on when people can truly and thoroughly solve the mystery of this statement.

Extended data:

As early as 1930, after the International Astronomical Union unified the boundaries of constellations, it issued an official statement confirming that there are thirteen constellations on the ecliptic. The existence of Ophiuchus is no longer news, but old news more than 80 years ago.

From the astrological point of view, the division of zodiac signs by astronomy is meaningless to astrology. Now the zodiac signs mentioned in astrology are actually symbols and do not correspond to the real constellations with the same name.

Astrology is a system to explain or predict people's fate and behavior through the relative position and movement of celestial bodies. In this system, celestial bodies (including sun, moon, mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, etc. ) are absolute protagonists, so how do we determine the position of these stars in the vast universe? In ancient times, the zodiac was used to determine the specific location of celestial bodies.
