Answer:

Saturn has 46 known moons (as of 4th May 2005 when 12 more were discovered).

These moons vary in size greatly, from the largest moon Titan (bigger than Mercury and Pluto), to other more controversial moons which are really just large rocks. Of the 12 most recently discovered, some are only 3 - 7 km wide, and take around 2 years to orbit the planet.

The number of moons is not stable, and more moons are being discovered all the time as detection techniques become more sophisticated.

Saturn is the planet with the second largest number of moons, with Jupiter catalogued as having the most.
