There are several space probes that have visited Saturn, but the most famous and successful is Cassini.

Here are some other probes that have studied Saturn:

* Pioneer 11: Flew by Saturn in 1979, providing the first close-up images of the planet.

* Voyager 1 and 2: Both flew by Saturn in the 1980s, providing more detailed images and data about the planet and its rings.

However, Cassini is the only probe that has orbited Saturn and studied it in detail for many years.
