WebNov 5, 2024 · Very long baseline interferometry (VLBI) is the technique that allows the most regular and precise observations of the nutation of the Earth by means of the observations of extragalactic radio sources, although according to , lunar laser ranging (LLR) has also the potential to determine celestial pole offsets (CPOs) with an accuracy comparable ... WebJan 23, 2024 · $\begingroup$ If you want a precise answer, you will also need to take nutation into account. The effect is less than an arcminute, so only ignore it if that's precise enough for your purposes. The search term to find an algorithm including nutation is "true obliquity of the ecliptic". $\endgroup$ –

The nutation of a planet occurs because the gravitational effects of other bodies cause the speed of its axial precession to vary over time, so that the speed is not constant. English astronomer James Bradley discovered the nutation of Earth's axis in 1728. Earth Nutation subtly changes the axial tilt of Earth with … See more 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 flight, or as an intended … See more • Libration • Teetotum See more If a top is set at a tilt on a horizontal surface and spun rapidly, its rotational axis starts precessing about the vertical. After a short interval, the top settles into a motion in which each point … See more In the 1961 disaster film The Day the Earth Caught Fire, the near-simultaneous detonation of two super-hydrogen bombs near the poles causes a change in Earth's nutation, as well as an 11° shift in the axial tilt and a change in Earth's orbit around the Sun.
