Is the thirteen constellations true?

The national aeronautics and space administration (NASA) said: Everyone said that we had changed constellations? No, we just calculated it. We are talking about astronomy, not astrology. About 3000 years ago, the Babylonians divided the zodiac into twelve equal parts, called the zodiac. Each region represents a constellation, and the time when the sun passes through each constellation varies greatly in a year. In addition, the Babylonians knew that there was a thirteenth Ophiuchus, which was not included for the convenience of calculation. Since 3000 years, the earth's axis has swung slightly, and the positions of constellations in the sky have also changed. In modern astronomy, constellations and houses are different, so NASA did some arithmetic instead of changing the zodiac.

The correct time of thirteen constellations

In fact, the zodiac and the constellation are completely different concepts. The ecliptic is the orbit of the earth around the sun, or the orbit of the sun from the center of the earth. The unit of measurement is degrees. The so-called zodiac is to divide the whole zodiac into 12 parts, each constellation accounts for 30 degrees, and the whole zodiac is 360 degrees. The zodiac, the zodiac in astrology, is a kind of "four-season calendar", which corresponds to the changes of the four seasons on the earth. When the ancients named the constellations, the astronomical Aries happened to be at the vernal equinox, so they borrowed Aries to name them, and other constellations were postponed in turn.

Astronomical constellations are not constellations measured by a stable index, but different constellations imagined by different cultures and connected by several stars.
