Ecliptic - Wikipedia
WEBPerpendicular to the ecliptic are the ecliptic poles, the north ecliptic pole being the pole north of the equator. Of the two fundamental planes, the ecliptic is closer to unmoving against the background stars, its motion due to planetary precession being roughly 1/100 that of the celestial equator.
Orbital pole - Wikipedia
WEBThe ecliptic is the plane on which Earth orbits the Sun. The ecliptic poles are the two points where the ecliptic axis, the imaginary line perpendicular to the ecliptic, intersects the celestial sphere. The two ecliptic poles are mapped below.
Ecliptic coordinate system - Wikipedia
WEBIn astronomy, the ecliptic coordinate system is a celestial coordinate system commonly used for representing the apparent positions, orbits, and pole orientations [1] of Solar System objects.

Orbits and the Ecliptic Plane - HyperPhysics
WEBThe apparent path of the Sun's motion on the celestial sphere as seen from Earth is called the ecliptic. The ecliptic plane is tilted 23.5° with respect to the plane of the celestial equator since the Earth's spin axis is tilted 23.5° with respect to its orbit around the sun.

Ecliptic Poles - an overview | ScienceDirect Topics
WEBThe formal definition of the ecliptic plane adopted by the IAU calls for the ecliptic pole to be the mean orbital angular momentum vector of the Earth–Moon barycenter. The normals to the actual orbital planes have inclinations relative to the ecliptic normal that are small, only a few degrees.
