42Invariable plane — The invariable plane of a planetary system is the plane passing through its barycenter (center of mass) which is perpendicular to its angular momentum vector. In the Solar system, about 98% of this effect is contributed by the orbital angular… …
43Rotation around a fixed axis — Rotational motion can occur around more than one axis at once, and can involve phenomena such as wobbling and precession. Rotation around a fixed axis is a special case of rotational motion, which does not involve those phenomena. The kinematics… …
