Names of the ancient twelve constellations

1, the twelve constellations were called Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces in ancient times.

2. More than 2000 years ago, the Greek astronomer Hipparchus (190 ~ 120 BC) divided the ecliptic into 12 segments, and divided it into 0 in spring.

3. Since the vernal equinox (that is, the ecliptic is zero degree), every 30 degrees is a house, and it is named after the main constellations contained in each house at that time, namely Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. They are called the zodiac. There are twelve constellations in all.
