What is the date of Ophiuchus?

Ophiuchus, also known as the Thirteen Constellations, has a corresponding birth date range of165438+1October 29th-65438+February 18.

Ophiuchus is one of the zodiac signs. Seen from the earth, Ophiuchus is located to the south of Ursa major, to the north of Scorpio and Sagittarius, and to the west of the Milky Way. Ophiuchus is the only constellation connected with another constellation-Ophiuchus. At the same time, Ophiuchus is the only constellation that spans the celestial equator, the Milky Way and the ecliptic. Ophiuchus is big and wide, rectangular, and the equator of the celestial sphere passes through this rectangle diagonally.

Although Ophiuchus spans a short galaxy, the center of the Milky Way 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.

Extended data

Astronomically speaking, as early as 1930, after the International Astronomical Union unified the boundaries of constellations, it issued an official statement confirming that there were 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.

The earliest ancient Babylonians imagined the whole universe as a big ball, and the trajectory of the sun on this big ball was called the ecliptic. At first, in order to show the position of the sun on the ecliptic, the ancients divided the ecliptic into 12 segments on average, and according to their initial observation results, they selected the 12 constellations that coincided with the 12 segments of the ecliptic as markers, which led to the origin of the names of the original 12 constellations.

With the development of astrology, the twelve constellations, which were originally used to indicate the position of the sun on the ecliptic, are gradually used to indicate the positions of other celestial bodies in astrology.

Therefore, whether there are twelve constellations or thirteen constellations in astronomy and whether there are big constellations or small constellations in astronomy has nothing to do with the astrological constellation system. What astrology needs is to honestly divide the ecliptic into twelve equal parts and give names to mark the position of celestial bodies.
