Node comes from nodus, knot. North specifies the crossing where the Moon goes toward the north side of the ecliptic.
How we know · epistemology
Orbital intersection geometry
The node follows from the Moon's orbital plane crossing the ecliptic northward. It helps describe eclipse geometry, but it is a location defined by planes rather than a body that emits a distinct influence.
