Update – 12 March 2025: Oh boy. A team of astronomers led from the University of Taiwan, the same team responsible for the previous update have just announced their discovery of an absolutely astonishing 128 new moons around Saturn. This brings the total to 274!

For those who noticed that the difference between the October 2019 update and this one is more than 128, those same researchers had also detected a few extra moons in the time between announcements. But I guess “3 moons discovered” isn’t very newsworthy, when we’re used to double and triple digit announcements!

UPDATE – 16 May 2023: I thought Jupiter was bad, with the constant discoveries of new moons making it hard to keep pages like this one updated. The new total is a staggering 145 moons. A team of scientists in Taiwan have been testing out new techniques and recently discovered 62 moons, in one single effort. This discovery has not yet been formally published, so we might have to do another update in a few months, but it’s still astounding that we now have planets with more than a hundred moons!

UPDATE: As of 7 October 2019, when the discovery of twenty extra moons was announced, Saturn now has 82 moons!

As of 16 May 2011, we’ve so far found 62 moons around Saturn.  Of these, only Titan is easy to see through binoculars or a small telescope.  Titan is the largest moon in the Solar system:  it’s about a third larger than Pluto and our own Moon, and is even slightly bigger than the planet Mercury!
