Constellation history

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 spring is divided into 0, and every 30 degrees away from the vernal equinox (that is, zero degree of the ecliptic) is a palace, and it is named after the main constellations contained in each palace at that time, which are Aries, Taurus, Gemini, Cancer, Lion, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces in turn, which are called the zodiac.
