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. Webthe axis slowly tracing a cone shape. The wobble is very slow; it takes the Earth 26,000 years to trace one complete conical shape. This wobbling motion of Earth on its axis is called precession. Because of precession, Polaris and Vega alternate as the North Star every 13,000 years. Polaris: The Current North Star Today the Earth's axis points ...
