WebEarth's axial tilt actually oscillates between 22.1 and 24.5 degrees. The reason for this changing obliquity angle is that Earth's axis also wobbles around itself. This wobble … WebJan 13, 2011 · The shift is caused by precession, the wobble in the Earth's axis caused by the gravitational attraction of the moon to the Earth's equator. Precession popped into the spotlight this week after ...

WebPrecession – As Earth rotates, it wobbles slightly upon its axis, like a slightly off-center spinning toy top. This wobble is due to tidal forces caused by the gravitational influences of the Sun and Moon that cause Earth to bulge at the equator, affecting its rotation. Webthe surface of a cone. Give it a nudge, however, and the axis will start gyrating wildly around the vertical, its motion tracing a cone ( drawing ). The spinning Earth moves like that, too, though the time scale is much slower--each spin lasts one day, but each gyration around the cone takes 26 000 years. The axis of the cone is perpendicular ... chronyc clients 見方

From our angle we can at one time peek over the north pole of the Moon, and then later in the lunar month we peek over the south pole. Over the entire four week cycle it gives the the effect of the Moon slowly “nodding its head yes.”.
