Earth precession rate
WebMar 31, 2024 · precession, phenomenon associated with the action of a gyroscope or a spinning top and consisting of a comparatively slow rotation of the axis of rotation of a spinning body about a line intersecting the spin axis. The smooth, slow circling of a spinning top is precession, the uneven wobbling is nutation. WebMar 23, 2024 · During this rotation, the change in direction of Earth's axis of rotation is known as precession. Earth's axis precesses in a 26,000-year cycle. As it does so, the …
