Answer: Saturn currently has 146 moons, confirmed by the International Astronomical Union.

As of 8 June 2023, Saturn has 146 moons. The number of moons increased substantially in May 2023 when 62 new moons were discovered by a team led by Edward Ashton. These new findings make the second largest planet in the solar system, Saturn, the “Moon King” of the solar system, and dethrone Jupiter by surpassing its 95 moons. Jupiter only has 95 moons whereas Saturn has 146 moons. These moons come in all shapes and sizes, starting from the colossal Titan which is larger than the planet Mercury, to tiny moonlets which are just a few kilometers wide. These numerous moons play a crucial role in shaping Saturn’s iconic rings and dynamic magnetosphere.

The moons are categorized on the basis of their size and shape.

  • The Titans: This group includes giants, such as Titan which is known for its thick atmosphere and potential oceans beneath its icy surface. Other notable members are Rhea, decorated with icy rings, and Dione, covered in craters and fractures.
  • Inner Moons: These smaller moons closer to Saturn are believed to be captured debris from collisions, orbiting in tight groups and shaping Saturn’s iconic rings.
  • Outer Moons: These moons are farthest moons and have irregular orbits and are likely captured objects and some discovered recently.

Conclusion

The exploration of Saturn’s moons has been a focus of spacecraft missions, such as NASA’s Cassini-Huygens mission, which provided valuable insights into the characteristics and mysteries of these celestial bodies. Ongoing research and future missions may reveal more about Saturn’s extensive moon system and deepen our understanding of the outer planets in our solar system.
