How Many Moons Does Saturn Have?
QUICK ANSWER
Saturn has 285 confirmed moons as of 2026, making it the planet with the most moons in our solar system. Saturn surpassed Jupiter in 2023 and has been adding more ever since. The largest moon is Titan, bigger than the planet Mercury and the only moon with a substantial atmosphere.
Saturn now has more moons than any other planet, recently overtaking Jupiter for the lead. The count keeps climbing as astronomers get better at spotting small, dim objects orbiting the planet. Most of Saturn's moons are tiny, but a few are large and scientifically fascinating.
How many moons does Saturn actually have?
As of 2026, Saturn has 285 confirmed moons. According to NASA, the count grew dramatically over the past few years as astronomers used new survey telescopes to find very small, dim moons that had been missed before. Most of Saturn's moons are tiny, often just 1 to 5 miles across, and are likely captured asteroids or fragments from collisions. The total is expected to keep growing as observation methods continue to improve.
Saturn surpassed Jupiter for most moons?
Yes, in 2023, and the gap has only widened since. For decades, Jupiter held the record with the most known moons in the solar system. Saturn caught up and pulled ahead when teams of astronomers ran dedicated searches for small outer moons using powerful telescopes. As of 2026, Saturn has 285 moons compared to Jupiter's 115. Most of the new discoveries on both planets are small irregular moons (captured objects), but Saturn happens to have many more of them, partly due to its position and gravity.
What are Saturn's biggest moons?
Saturn has seven moons large enough to be roughly spherical under their own gravity. Titan is by far the largest, with a diameter of about 3,200 miles, bigger than the planet Mercury. Rhea (950 miles), Iapetus (910 miles), Dione (700 miles), Tethys (660 miles), Enceladus (310 miles), and Mimas (250 miles) round out the major moons. Most of the rest are much smaller. Several of Saturn's moons are scientifically remarkable: Titan has lakes of liquid methane, Enceladus has water geysers, and Iapetus has a striking two-toned color scheme.
Where do all these moons come from?
Two main groups, two origins. The seven large moons probably formed alongside Saturn from the same disk of gas and dust that built the planet, orbiting in regular, near-circular paths. The rest are mostly irregular outer moons, captured objects with steep, eccentric, or backwards orbits. Saturn's gravity has been collecting wandering asteroids and comet fragments for billions of years. Some of the smallest moons may even be debris from past collisions between larger satellites, broken apart and still orbiting Saturn in clusters.
Saturn has 285 known moons, the most of any planet, with the count still climbing. Titan, Enceladus, and the rest of the major moons make Saturn's satellite system one of the most scientifically rich destinations in the solar system. Jupiter held the record for a long time, but Saturn has now taken it convincingly and isn't likely to give it back anytime soon.
