Nutation (from Latin nūtātiō 'nodding, swaying') is a rocking, swaying, or nodding motion in the axis of rotation of a largely axially symmetric object, such as a gyroscope, planet, or bullet in …

Those who have studied the gyrations of a spinning top will recall that, in addition to precessing, a top may nutate, or nod up and down (Latin nutare, to nod), the amplitude and type of nutation …

Nutation, in astronomy, a small irregularity in the precession of the equinoxes. Precession is the slow, toplike wobbling of the spinning Earth, with a period of about 25,772 years.

Dec 14, 2018 · Nutation and precession are the periodic and long-term motion of the Earth's spin axis in space. The direction of the Earth's axis in space, shown in orange, changes over time …

Nutation describes an oscillating or nodding motion in the axis of rotation of a spinning object. It represents a small, periodic oscillation superimposed upon a larger, more stable rotational …

These also included precession and nutation, phenomena usually observed only through global networks of large radio telescopes. Georgina Jedikovska, Interesting Engineering, 4 Sep. 2025 …

Oct 3, 2025 · Nutation and precession refer to the periodic and long-term motion of Earth's spin axis in space, with the axis's direction changing over time relative to distant celestial objects …

Nutation is a periodic oscillation in the orientation of the axis of a rotating body, specifically occurring in the context of gyroscopic motion. This phenomenon is caused by external forces …

Nutation was discovered by James Bradley from a series of observations of stars conducted between 1727 and 1747. These observations were originally intended to demonstrate …

In the case of the Earth, nutation is the periodic oscillation of the Earth's axis of rotation around its average position on the celestial sphere, due to the external forces of gravitational attraction …
