Lunar standstill: every 18.6 years, the declination range of the Moon reaches a maximum or minimum.
Lunar precession is a term used for three different precession motions related to the Moon.
First, it can refer to change in orientation of the lunar rotational axis with respect to a reference plane, following the normal rules of precession followed by spinning objects.
In addition, the orbit of the Moon undergoes two important types of precessional motion: apsidal and nodal.
