nutation

/njuːˈteɪʃ(ə)n

noun [mass noun]

1A periodic variation in the inclination of the axis of a rotating object.

1.1 Astronomy A periodic oscillation of the earth’s axis which causes the precession of the poles to follow a wavy rather than a circular path.There is a small periodic effect called nutation superimposed on precession caused by the motion of the perihelion of the Moon....

In addition to the precession and nutation of the Earth's rotational axis, the Earth itself undergoes a wobble such that the crust wanders about the rotational axis with a combination of two periods and amplitudes.
Bessel's work in determining the constants of precession, nutation and aberration won him further honours, such as a prize from the Berlin Academy in 1815.

2 Botany The circular swaying movement of the tip of a growing shoot.

Origin

Early 17th century (denoting nodding of the head): from Latin nutatio(n-), from nutare 'to nod'.
