What are the zodiac signs? The name of each constellation

The word "zodiac" comes from the Greek zodiakos, which means zoo. In the eyes of the Greeks, constellations are made up of various animals, which is the origin of the names of the twelve constellations.

In astronomy, the orbit of the sun around the earth with the earth as the center is called the ecliptic. The width of the ecliptic is 16 degrees, 360 degrees around the earth. The ecliptic plane includes the orbits of all planets except Pluto, as well as the constellations, exactly every 30 degrees.

Each interval has a constellation, a total of twelve constellations, called the "Zodiac".

The sun runs from west to east on the ecliptic and circles the sky once a year. There are twelve constellations on a belt on both sides of the ecliptic. They are Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. People on earth can see them one after another in a year.
