What is the zodiac? It comes from the constellation.

Around the 5th century BC, Babylonian astronomers first used the concept of the zodiac. Imagine the whole sky as a big ball, and the stars are all distributed on the spherical shell. This is the so-called celestial sphere. The ecliptic is the trajectory of the sun on the celestial sphere. 8 degrees on each side of the ecliptic is the ecliptic. Planets all move on the ecliptic. Babylonians also divided the zodiac into twelve regions, but the names of these regions came from the ancient Greeks. In fact, the names of most constellations come from Greek mythology. If the equator of the earth expands infinitely and intersects the ecliptic, one of the intersections is the vernal equinox. From the vernal equinox, divide an area every 30 degrees, which is Zodiac Palace 12. Maybe you are familiar with the following names: Aries Palace, Taurus Palace, Twin Uterus, Cancer Palace, Lion Palace, Virgo Palace, Libra Palace, Scorpio Palace, Sagittarius Palace, Capricorn Palace, Aquarius Palace and Pisces Palace. These names are named after the zodiac where each region is located.
