The planet with the most satellite moons is Saturn with 62 moons! Titan, Saturn's largest moon, and the second-largest in the Solar System, is larger than the planet Mercury, although less massive, and is the only moon in the Solar System to have a substantial atmosphere.
Uranus has 27 moons, while Neptune has 14 moons. We should also note that Venus and Mercury has no moons in their orbit. Of course, as we all know, Earth has but one moon. This list currently exclude dwarf planets, such as Pluto, in our solar system.
