For much of the 20th century, Saturn was known to have a modest family of moons. Today, the number has exploded. As of the latest counts in 2026, the ringed planet has either 274 or 292 confirmed moons, depending on which official source you consult. This rapid expansion has cemented Saturn’s position as the undisputed moon king of the solar system.
The majority of these new discoveries are tiny, irregular fragments of rock and ice, often no more than a few kilometers across. They were detected using advanced imaging techniques that push the limits of modern telescopes, revealing a vast population of objects that had previously been invisible.
How Many Moons Does Saturn Have? (2025 Updated Count)
The exact number depends on the definition used. NASA’s Science portal lists 274 confirmed moons as of March 2025. However, Wikipedia, which includes objects with confirmed orbits updated through early 2026, lists a total of 292 moons. Both figures represent the highest moon counts of any planet in the solar system.
274 (as of March 2025)
292
#1 — Most moons
Titan (larger than Mercury)
Enceladus (subsurface ocean)
128 new moons (2025)
The rapid jump in numbers tells a story of technological progress and persistent surveying. Here are the key takeaways from the most recent data:
- Saturn has overtaken Jupiter as the planet with the most known moons, thanks to recent telescopic surveys.
- The official count varies between 274 (NASA) and 292 (Wikipedia) depending on how “moon” is defined and whether unconfirmed candidates are included.
- Most of Saturn’s new moons are tiny irregular moons, likely captured asteroids or Kuiper Belt objects.
- Titan is the only moon in the solar system with a thick atmosphere and stable liquid surface lakes (methane).
- Enceladus is a prime candidate in the search for extraterrestrial life due to its subsurface ocean.

Does Saturn Have the Most Moons in the Solar System?
Yes, Saturn holds the top spot. With at least 274 confirmed moons, it has far more than any other planet. To put that into perspective, Saturn has more moons than all the other planets in the solar system combined.
How Many Moons Does Jupiter Have?
Jupiter, the previous record holder, currently has 95 confirmed moons. While 95 is a large number, it is less than half of Saturn’s count.
How Many Moons Do the Other Planets Have?
The numbers drop significantly for the outer ice giants. Uranus has 27 known moons, and Neptune has 16. Mars, the only other rocky planet with natural satellites, has two small moons: Phobos and Deimos. Both Mercury and Venus have zero.
Saturn leads with 274–292. Jupiter has 95. Uranus has 27. Neptune has 16. Earth has 1. Mars has 2. Mercury and Venus have 0. Saturn’s count is more than Jupiter, Uranus, Neptune, Earth, and Mars combined.
How Many Moons Does Saturn Have in Order? (From Largest to Smallest)
Saturn’s moons are not evenly matched. They range from planet-sized giants to tiny space rocks. In order from largest to smallest, the major moons are: Titan, Rhea, Iapetus, Dione, Tethys, Enceladus, Mimas, and Hyperion. Beyond these, hundreds of smaller irregular moons form the bulk of the new discoveries.
What Is the Largest Moon of Saturn?
The largest moon is Titan. It is the second-largest moon in the entire solar system and is actually larger than the planet Mercury. Titan is unique because it has a thick atmosphere and stable liquid lakes made of methane on its surface.
A World of Small Irregulars
The vast majority of the newly discovered moons are categorized as “irregular.” These are small, oddly shaped objects with distant, tilted, or elliptical orbits. Scientists believe most of them are captured asteroids or fragments from the Kuiper Belt.
Why Does Saturn Have So Many Moons?
According to researchers, several factors contribute to Saturn’s exceptional moon count. The planet is a “master of gravitational capture,” effectively pulling in passing objects from space. Collisions between these captured bodies have also created numerous smaller fragments in Saturn’s orbit, adding to the census.
Improved detection technology plays a critical role. A research team led by Dr. Edward Ashton used the Canada-France-Hawaii Telescope and image stacking techniques—combining multiple images along predicted orbits—to find faint objects as small as 3 km. This method, applied to observations from 2023, directly resulted in the announcement of 128 new moons in March 2025.
Saturn’s massive gravity well allows it to capture passing asteroids and Kuiper Belt objects more efficiently than Jupiter. This position in the outer solar system, combined with its strong gravitational pull, makes it a natural collection point for orbital debris.
Researchers have also been able to identify new moons by re-examining archival observations from instruments like the Subaru telescope, which took data between 2004 and 2007. This combination of new surveys and historical data reanalysis is likely to continue yielding results.

- 1789 — Herschel discovers Mimas and Enceladus.
- 1898–1966 — Hyperion, Phoebe, and Janus/Epimetheus are discovered.

Why Do Moon Counts Differ Between Sources?
It can be confusing to see two different numbers. The difference between NASA’s 274 and Wikipedia’s 292 comes down to how the data is classified and updated. NASA’s figure reflects the confirmed moons as of the March 2025 announcement. Wikipedia’s figure includes subsequent updates through 2026, counting objects with confirmed orbits.
| Established Information | Information That Remains Unclear |
|---|---|
| Saturn has the most known moons of any planet. | Whether the exact total will increase as more faint objects are detected. |
| The vast majority of new moons are small irregular moons (2–5 km). | Whether some small objects are ring fragments rather than true moons. |
| Titan and Enceladus remain the most scientifically important moons. | Whether classification criteria will differ between sources in the future. |
Why Saturn Keeps Winning the Moon Race
Saturn’s dominance in moon count is a direct result of its physical properties and our improving technology. Its massive gravity allows it to capture passing objects more effectively than any other planet. Advanced telescopes, such as the Canada-France-Hawaii Telescope used for the 2025 discoveries, can now detect objects as small as 3 km. Researchers believe there may be potentially thousands of objects orbiting Saturn that could eventually be confirmed as moons, meaning the count is expected to continue growing.

What Is the Current and Future Outlook for Saturn’s Moon Count?
The number of known moons orbiting Saturn will almost certainly keep rising. Further deep-sky surveys are expected to find more tiny irregular moons, potentially pushing the total over 300. The upcoming Dragonfly mission from NASA will explore Titan in the 2030s, while analysis of Enceladus’s subsurface ocean continues through data from previous missions.
