What apparent path does the ecliptic great circle represent on the celestial sphere?

The apparent path the Sun traces across one year.

The ecliptic is defined as another significant great circle that traces the Sun's apparent path across the celestial sphere over the duration of one full year. This apparent motion is a direct consequence of the Earth undergoing its annual revolution around the Sun, meaning the ecliptic plane is effectively the projection of the Earth’s orbital plane outward into space. Because it defines the Sun's yearly route, the ecliptic is indispensable for understanding seasonal variations and tracking calendar cycles. Furthermore, the condition for an eclipse is that the Moon's orbital plane must intersect this ecliptic plane very closely or exactly.
