Extended data

In western astrology, constellation 12 is synonymous with the orientation of the universe. When a person is born, the position of each constellation on the ecliptic shows a person's innate character and talent. Zodiac 12 symbolizes the psychological level and reflects a person's behavior.

So the ecliptic is divided into 12 constellation, which is called 12 constellation. Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces.

The twelve constellations, namely the zodiac, are astrological regions that describe the sun passing through the zodiac on the celestial sphere, 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 no longer conforms to astrology.
