around the Earth in an elliptical orbit with a period of 27.32166 days - this is the so-called sidereal month (that is, the movement is measured relative to the stars);
rotation of the plane of the lunar orbit: its nodes (the points of intersection of the orbit with the ecliptic) are shifted to the west, making a complete revolution in 18.6 years. This movement is precessional;
rotation of the major axis of the lunar orbit (lines of apsides) with a period of 8.8 years (occurs in the opposite direction than the movement of the nodes indicated above, that is, the longitude of the perigee increases);
periodic change in the inclination of the lunar orbit with respect to the ecliptic from 4°59' to 5°19';
periodic change in the size of the lunar orbit: perigee - from 356.41 to 369.96 thousand km, apogee - from 404.18 to 406.74 thousand km;
the gradual removal of the Moon from the Earth due to tidal acceleration (by 38 mm per year) [12] [13], so its orbit is a slowly unwinding spiral
