A resonance between the precession of Saturn's rotational axis and that of Neptune's orbital axis (both of which have periods of about 1.87 million years) has been identified as the likely source of Saturn's large axial tilt (26.7°). Source: Internet
A precession, or tilt, in the orientation of the rotor causes the London moment magnetic field to shift relative to the housing. Source: Internet
A secular resonance occurs when the precession of two orbits is synchronised (usually a precession of the perihelion or ascending node ). Source: Internet
Astrologers usually have only a small knowledge of astronomy, and often do not take into account basic principles—such as the precession of the equinoxes, which changes the position of the sun with time. Source: Internet
Astronomy In astronomy, precession refers to any of several gravity-induced, slow and continuous changes in an astronomical body's rotational axis or orbital path. Source: Internet
