Saturn currently has 61 known moons, six of which have been discovered in data gathered by Cassini. Two more possible discoveries by Cassini still await final confirmation, as the objects might not be proper moons but instead are transient in nature. When Cassini-Huygens was launched in 1997 there were only 18 known Saturnian moons. In addition to the Cassini discoveries, reanalysis of data from the Voyager 2 spacecraft, as well as Hubble observations and ground-based observations of Saturn have led to the further discoveries.
