Are the thirteen constellations real?

When the concept of the thirteen zodiac signs came out, many people expressed disbelief, and some were surprised to find that they were not of any particular zodiac sign. According to the horoscope table after the change date, many people's horoscopes have quietly changed. Many people also question whether the thirteen zodiac signs are true? Why are there thirteen constellations? Some say it is true, some say it is false, so are the thirteen constellations true or false?

In fact, the thirteen constellations are the boundaries of the all-sky constellations determined by the International Astronomical Union in 1982. The ecliptic passes through thirteen constellations. If you look closely, there is even a constellation, that is Cetus, but the ecliptic within the boundary of Cetus is less than a quarter of a degree.

Some people also asked, why do we usually use the twelve zodiac signs to analyze personality? That's because the twelve constellations are an astrological concept, or more precisely, the "zodiac." The twelve zodiac constellations are divided into 12 equal parts at the seven points of the vernal equinox. When a person is born, the zodiac sign of the sun is called that person's "zodiac sign". In astrology, this is a person's "sun sign".

After clarifying the zodiac, in fact, the increase or decrease of constellations in astronomy, or the change of the vernal equinox caused by the activation of the earth's axis, will not affect the "zodiac". So it will not change from the twelve zodiac signs to the thirteenth zodiac sign. But there are actually thirteen stars that are passed through by the ecliptic.

To add, the Western calendar uses the Gregorian calendar, which is customized solely based on the movement of the sun, so the dates of the twelve zodiac signs in the Gregorian calendar are fixed. The twelve zodiac signs are based on the sun. These dates are simply divided into twelve categories based roughly on the sun. But if it is astrology, the various characteristics of the twelve constellations need to be viewed in combination with many changes, such as the classification of water signs and fire signs.

So the thirteen constellations do exist. In astronomy, it is Ophiuchus, which was actually discovered by scientists a long time ago. Scientific records show that when a British astronomer was observing the changes in the stars, he found that there was some error in time every year. Over time, the time error became larger and larger, so there is actually another constellation crossing the ecliptic, which is Ophiuchus.
