Ecliptic
The ecliptic is the apparent path that the Sun traces out in the sky, as it appears to move in the sky in relation to the stars, this apparent path aligns with the planets throughout 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. It should be distinguished from the
invariable ecliptic plane, which is the vector sum of the
angular momenta of all planetary orbital planes, to which
Jupiter is the main contributor.
