The twelve constellations are introduced as follows:

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.
