Typically, the stated rotation period for a giant planet (such as Jupiter, Saturn, Uranus, Neptune) is its internal rotation period, as determined from the rotation of the planet's magnetic field. For objects that are not spherically symmetrical, the rotation period is, in general, not fixed, even in the absence of gravitational or tidal forces
The entire structure rotates with a period of 10 h 39 m 24 s (the same period as that of the planet's radio emissions) which is assumed to be equal to the period of rotation of Saturn's interior. [73] The hexagonal feature does not shift in longitude like the other clouds in the visible atmosphere. [74] The pattern's origin is a matter of much ...
In 2019 NASA announced Saturn's rotational period as 10 hours, 33 minutes, 38 seconds, calculated using Saturnian ring seismology. Vibrations from Saturn's interior cause oscillations in its gravitational field. This energy is absorbed by ring particles in specific locations, where it accumulates until it is released in a wave.

In the case of Saturn, however, this appears to be impossible, as the period varies at the timescale of ten years. In 1980–1981 the periodicity in the radio emissions as measured by Voyager 1 and 2 was 10 h 39 min 24 ± 7 s, which was then adopted as the rotational period of Saturn.
[4] [5] [10] It rotates with a period of 10h 39m 24s, the same period as Saturn's radio emissions from its interior. [11] The hexagon does not shift in longitude like other clouds in the visible atmosphere. [12] Saturn's hexagon was discovered during the Voyager mission in 1981, and was later revisited by Cassini-Huygens in 2006.
The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy , it usually applies to planets or asteroids orbiting the Sun , moons orbiting planets, exoplanets orbiting other stars , or binary stars .
Saturn's retrograde ends in Pisces on November 15, 2024, the same day as the Taurus full moon. The planet of karmic restriction begins to regain forward movement, allowing us to close doors on ...
