Ecliptic
The ecliptic is the apparent path the Sun traces out along the sky — independent of Earth's rotation — in the course of the year. More accurately, it is the intersection of the celestial sphere with the ecliptic plane, which is the geometric plane containing the mean orbit of the Earth around the Sun.
