Extended data:

The ecliptic passes through 13 in 88 constellations. Except for a small number of Ophiuchus, they are Pisces, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn and Aquarius, which are collectively called the zodiac signs. The names of the zodiac have indeed undergone many changes, many of which are related to myths, and most of them are named after animals.

The sun runs on the ecliptic, and the orbits of other planets around the sun intersect with the orbit of the earth at a small angle, that is, the planets intersect with the ecliptic at a small angle, which is called orbital inclination. Among the nine planets, except Pluto, Mercury has the largest orbital inclination of 7. The orbital inclination of other planets is generally between 1 ~ 3, while Pluto exceeds 17.

This shows that all other planets except Pluto, no matter where it runs, their positions in the sky are always in the sky not far from the ecliptic. They often appear or pass through this or that constellation and never go to other constellations. The celestial sphere with a width of 8 on each side of the ecliptic, * * * 16, is called the zodiac, also known as the zodiac. The zodiac is the place where the sun, moon, planets and other celestial bodies haunt and the corridor through which they pass.
