Overview

• Astronomers have discovered 128 new moons orbiting Saturn, bringing the planet's total known moon count to 274, far surpassing Jupiter's 95 moons.
• The International Astronomical Union formally ratified the discovery on March 11, 2025, following detailed observation data collected between 2019 and 2023.
• All newly identified moons are irregular, small in size, and likely fragments from collisions within Saturn's moon system over the past 100 million years.
• The discoveries were made using the France Hawaii Telescope, leveraging image-stitching techniques that enhanced the visibility of faint objects in Saturn's orbit.
• The findings provide new insights into the evolution of Saturn's satellite system and the broader dynamics of the Solar System's history.
