While approaching Saturn in 2004, Cassini found that the radio rotation period of Saturn had increased appreciably, to approximately 10 h 45 m 45 s ± 36 s. [ 91 ] [ 92 ] An estimate of Saturn's rotation (as an indicated rotation rate for Saturn as a whole) based on a compilation of various measurements from the Cassini , Voyager , and Pioneer ...
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 Sun has an equatorial rotation speed of ~2 km/s; its differential rotation implies that the angular velocity decreases with increased latitude. The poles make one rotation every 34.3 days and the equator every 25.05 days, as measured relative to distant stars (sidereal rotation).
One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere. [22] Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery.
The CDA was an in situ instrument that measured the size, speed, and direction of tiny dust grains near Saturn. ... In 2019 NASA announced Saturn's rotational period ...
In gravitationally bound systems, the orbital speed of an astronomical body or object (e.g. planet, moon, artificial satellite, spacecraft, or star) is the speed at which it orbits around either the barycenter (the combined center of mass) or, if one body is much more massive than the other bodies of the system combined, its speed relative to the center of mass of the most massive body.
The speed of the planet in the main orbit is constant. ... as conservation of angular momentum does via rotational symmetry for the second ... Saturn 9.53707 10775. ...
The problem is that the components of Saturn's atmosphere, especially hydrogen and helium, travel at different speeds and do not attest to Saturn's own rotation. [8] Therefore, Helled's research was based on calculating the speed of rotation by measuring Saturn's gravitational field and calculating its density and oblateness (the fact that its ...
