Why was Ophiuchus destroyed? The real Ophiuchus.

When people mention constellations nowadays, most of them only remember the zodiac, that is, the twelve constellations, but there is actually a thirteenth constellation besides the twelve constellations, Ophiuchus. However, Ophiuchus has been neglected for a long time, and its position has been excluded from the twelve constellations for a long time. There must be some reasons why it will be excluded. Why Ophiuchus was eliminated is because it ranked thirteenth. Westerners are quite taboo about the number thirteen, so they ruled it out. Moreover, the legend of Ophiuchus in western mythology is not very good. Asclepius, the god of medicine, tried to save his dead mother with a snake, which was known by Pluto. He was killed by lightning, which is somewhat shocking in image. Not to mention thirteen is not good in western culture, God was betrayed and killed by his thirteenth disciple, and the legend 13 is a symbol of the devil, so slowly, Ophiuchus, ranked thirteenth, disappeared. Ophiuchus is a real constellation. It is one of the zodiac constellations, but it does not belong to one of the zodiac constellations. Seen from the earth, it is located to the south of Ursa, to the north of Scorpio and Sagittarius, and to the west of the Milky Way. 1928, the international astronomical union identified Ophiuchus as one of the thirteen constellations on the ecliptic at its international astronomical congress. Ophiuchus, which actually exists in astronomy, never belongs to the zodiac in western astrology. The difference between Ophiuchus and astrology has always been an old topic of debate among astrologers, and it is still under discussion. The position of Ophiuchus The present situation of Ophiuchus is relatively large and wide. Its present situation is like a rectangle, and the celestial equator just passes through it. Although the Milky Way across Ophiuchus is short, its center is Sagittarius, not far from Ophiuchus. The Milky Way has a prominent part here, forming the widest area of the Milky Way. You can see the latitude change between +80 and 80. The brightest star α in Ophiuchus is a white giant (A5Ⅲ) with an apparent magnitude of 2.08, an absolute magnitude of 0.96 and a distance of 54 light years. In other areas, there is a big cluster.
