Which country do the twelve constellations come from?

The twelve constellations originated in ancient Babylon and were perfected by ancient Greek astronomers.

The theory of twelve constellations originated in Babylon. More than 2000 years ago, Greek astronomer Baccus divided the ecliptic into twelve segments to show the position of the sun on the ecliptic. The vernal equinox is 0 degrees away from the vernal equinox, that is, the ecliptic is zero degrees, and every 30 degrees is a palace named after the main constellations contained by officials at that time, which are Aries, Taurus, Gemini, Cancer, Lion, Foreign Woman, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and other palaces in turn.

There are twelve constellations, and babies born when the earth moves to each equal constellation will always have some similar characteristics when they grow up, including behavioral characteristics. The rich imagination and creativity of these associations are connected in series, which makes the humanity of these constellations visualized, increases the color of myths and becomes an important part of culture, mainly referring to Greek and Roman myths. This numerology has evolved and spread for at least 5000 years.

The change of the twelve constellations from now on

The twelve constellations, the zodiac, are astrological descriptions of the twelve regions on the celestial sphere where the sun passes through the zodiac, including Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. Although Ophiuchus also passes through the zodiac, it is not in the zodiac used in astrology.

Astrology's definition of the ecliptic only refers to the twelve equally divided regions of the ecliptic, which is different from astronomy. After the International Astronomical Union standardized the constellation boundary in 1928, there were 13 constellations on the ecliptic. Because of precession, the zodiac in 2 1 century is not consistent with astrology.
