Earth axis wobble period

WebIn the case of Earth, the principal sources of tidal force are the Sun and Moon, which continuously change location relative to each other and thus cause nutation in Earth's axis. The largest component of Earth's nutation has a period of 18.6 years, the same as that of the precession of the Moon's orbital nodes. http://astro.wsu.edu/worthey/astro/html/lec-precession.html
