The Full Story
As of 2023, Saturn is the solar system's moon champion with 146 confirmed moons, surpassing Jupiter's 95. The discovery of 62 new Saturnian moons in 2023 (led by astronomer Edward Ashton) pushed Saturn into the lead. Saturn's largest moon, Titan, is the second-largest moon in the solar system (5,150 km diameter — bigger than Mercury) and is the only moon with a substantial atmosphere. Titan's surface features methane lakes and rivers, making it one of the most intriguing targets for astrobiology. Jupiter's four largest moons — Io, Europa, Ganymede, and Callisto — were discovered by Galileo in 1610. Ganymede is the largest moon in the solar system at 5,268 km diameter. Uranus has 27 moons and Neptune has 16.
