Has the constellation date really changed?

For reference only, the first part is some theories, and those who can't stand it can be seen directly from the last part of Ophiuchus Interpretation. _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ For example, in London in June and February of 5438, it gets dark around 3 pm and the sunrise is after 8 pm. However, with the arrival of spring, the orbit of the sun (ecliptic) will slowly turn to the north latitude, and enter the northern hemisphere after crossing the equator on March 2 1 day, directly shining in the northern hemisphere. Around June, the North Pole will enter a state of eternal day (at this time, the South Pole will enter a state of eternal night), because the sun is directly in the northern hemisphere at this time, until June 2 1 day, the sun begins to move to the south latitude, and September 2 1 day passes through the equator. Why is the sun's orbit so complicated? That's because the earth's axis is not perpendicular to the ecliptic plane, but has an inclination of 231/2 degrees, so half of the sun's orbit (ecliptic) passes through the northern hemisphere and the other half passes through the southern hemisphere. Due to the tilt of the earth's axis, the time when the sun shines on the northern and southern hemispheres is different, including four seasons: spring, summer, autumn and winter. When the sun's orbit passes through the equator on March 2 1 day and September 2 1 day, it will make the time of day and night equal (because the sun does not illuminate the southern hemisphere or the northern hemisphere at this time), which is called the vernal equinox. These two times are about the vernal equinox and the autumn equinox in the northern hemisphere. In Babylonian times, the vernal equinox of March 2 1 happened to be the time when the sun entered Aries, which is why the Babylonians took these 30 days as the first month. However, in Greek and Roman times, there was a big problem with this law. Greek and Roman astrologers (said to be the Greek astrologer Sipacus mentioned earlier) found that the sun did not set in Aries on the day of the vernal equinox, but moved to Pisces, only to find that the constellation behind the zodiac is not fixed, but moves at a very slow speed, which is the precession phenomenon mentioned earlier. After years of research, astronomers also found that the earth's rotation axis runs in a cycle of 26,000 years. 14000 BC, Vega was the north pole of the sky; 3000 years ago, the North Pole of the Earth was Dragon Alpha, and the vernal equinox was in Aries. Today, according to astronomical observation, the north pole of the sky is Polaris, and the vernal equinox has fallen in the middle of Pisces. Return to the ecliptic and the star ecliptic, but for ancient astrologers, the vernal equinox is the starting point of Aries and an important coordinate to define the position of the planet. If it keeps moving or changing, it will bring considerable trouble to determine the position of the planet. So around 1 century BC, Greek astrologers and astronomers decided to keep the position of vernal equinox sun on March 2 1 day every year as the starting point of Aries on the ecliptic (at this time, the position of vernal equinox and the sun is close to that of Pisces on the ecliptic), and kept the Babylonian way. Since then, the ecliptic has been divided into 12 equal parts, keeping the original name, that is, such a ecliptic system is called [tropical ecliptic]. However, astrologers in India use different ideas. They insist on the position of Aries in the sky as the starting point of the ecliptic. This calculation method of the ecliptic is called the stellar ecliptic, and these two different concepts of the ecliptic system are called the ecliptic divergence. Today's astronomy needs more accurate methods to distinguish the ecliptic. Astronomers can't accept the coordinate way that the ancients roughly divided the sky into twelve constellations. They made a more detailed distinction between the constellations on the ecliptic to facilitate the observation of planets. The correct statement that European and American astrologers often return to ecliptic astrology is which constellation the sun belonged to when you were born. At present, most astrologers in Europe and America use the ecliptic, but if you go to an astrologer in India, he may use the stellar ecliptic. For example, your birthday is April 2 1. For astrologers who use the zodiac, you are Taurus, but for Indian astrologers who use the star system, you are Aries.

Modern astrologers also have more elaborate methods to calculate the constellation of birth date, so people born on March 2 1 may not be Aries, but they may still be Pisces because they are only one minute away. In the eyes of astrologers, it is absolutely not because you were born at the junction of Pisces and Aries that you are half Aries and half Pisces. These specious statements have caused many astrologers a headache. As for why many people have the characteristics of different constellations at the same time, or show different personalities at different times, there are more rigorous methods to explain this in astrology. Interpretation of Ophiuchus Modern astronomers claim to have discovered Ophiuchus, the 13 constellation on the ecliptic, which even caused quite a controversy. Many astronomers think that the ecliptic should not be roughly divided into 12 constellations, or astrologers know the existence of Ophiuchus, but turn a blind eye. In fact, this case involves the debate between astronomy and astrology. From a scientific point of view, astrology is not a rigorous knowledge system, but astronomy and astrology have always been the same subject in early history. It was not until after the scientific age that the two disciplines parted ways and have been attacking each other ever since. Ophiuchus was not suddenly discovered by astronomers. In fact, Ophiuchus has always been near the ecliptic, between Scorpio and Sagittarius. The image of Ophiuchus is a man holding a giant snake. If we observe the starry sky, we will find Ophiuchus stepping into the ecliptic, just between Scorpio and Sagittarius. As early as the Pan-Greek era, Ophiuchus appeared in the constellation group in the records of Egyptian astronomer and astrologer Ptolemy. Ophiuchus was indeed included in the constellation group of the zodiac at a certain period, and even included the southern constellation. Such a * * * has 14 zodiac constellations. It was only in the Egyptian era that Ptolemy divided the ecliptic into 12 according to the Babylonians and deleted the constellation on the ecliptic as 12. This concept of the ecliptic has been used ever since. Modern astronomers only use this constellation to express inaccurate and unscientific astrology. Today, most astronomers add Ophiuchus to the constellation group on the ecliptic, making the ecliptic into thirteen unequal regional coordinates. However, this method of marking the position of the ecliptic is only used in astronomy, and most astrologers still use it. Since the vernal equinox, the zodiac has been divided into twelve equally divided constellations, also called "Return to the Zodiac".
