The origin and legend of the twelve constellations

More than 2000 years ago, the Greek astronomer Hipparchus (190 ~ 120 BC) divided the ecliptic into twelve segments, with spring divided into zero, and every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic) as a palace, taking the main constellations contained in each palace at that time.

In turn, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces and other houses are called the zodiac. There are twelve constellations in all. Babies born when the earth moves to every fraction (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics.

By connecting these associations (rich imagination and creativity) in series, these constellations are visualized; It also adds the color of myth and becomes an important part of culture (mainly Greek and Roman mythology). This set of numerology has been developed and circulated for at least five thousand years, represented by these twelve constellations respectively.

Extended data:

The twelve constellations are the twelve regions in astrology that describe the sun passing through the ecliptic 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 is not consistent with astrology. ?
