No, it is not possible that Saturn acquired its rings from the planet Uranus or via one or more of its moons. The rings of Saturn are believed to have originated from within the Saturnian system itself, rather than being captured from another planet or moon.
The most widely accepted hypothesis regarding the formation of Saturn's rings is the "Roche limit" theory. According to this theory, the rings were formed from the debris of a shattered moon or a moon that failed to form due to tidal forces. These tidal forces, caused by Saturn's gravitational pull, exceeded the moon's structural integrity at a certain distance from the planet, known as the Roche limit. As a result, the moon was torn apart by tidal forces, and its fragments spread out to form the rings.
The rings of Saturn consist of countless small particles, ranging from tiny grains to larger boulders, all orbiting around the planet. They are composed primarily of ice particles, with some rock and dust mixed in. The exact details of the ring formation process and the mechanisms that have shaped them over time are still the subject of scientific study and investigation.
In summary, while the origin and evolution of Saturn's rings continue to be areas of active research, there is currently no evidence to suggest that they were acquired from Uranus or any of Saturn's moons.
