The Sun, Moon, Winter, and Summer

Leveling its position and measure? The Sun moves North? Above?

This diagram illustrates the celestial paths of the sun and moon relative to the ecliptic, equator, and lunar orbit during various seasons. It uses the traditional "Three Paths" system: the Yellow Path (Ecliptic), the Red Path (Equator), and the White Path (Lunar Orbit).

Equatororiginal: "chìdào" (赤道), literally the "Red Path."

Eclipticoriginal: "huángdào" (黄道), literally the "Yellow Path," representing the Sun's apparent annual path.

Lunar Pathoriginal: "báidào" (白道), literally the "White Path," representing the Moon's orbit relative to the Ecliptic.

This diagram serves as a visual guide for predicting the positions of the celestial bodies. By showing the intersection of the "Three Paths," an astronomer could determine when the Moon might pass through the Earth's shadow (causing an eclipse) or how the height of the Sun changes between the Summer and Winter solstices.
