Jupiter: The Planet with the Most Moons
Jupiter's Moon Count
Jupiter holds the record for the most moons in our solar system. As of the latest count, Jupiter has 39 known moons. This number was recently updated following the International Astronomical Union's announcement on May 16, which confirmed the discovery of 11 new moons orbiting the planet1. These newly discovered moons are relatively small, each measuring between 2 to 4 kilometers in diameter, and they have irregular, elongated, and inclined orbits1.
Distribution of Moons in the Solar System
The distribution of moons across the solar system varies significantly among the planets. The number of moons a planet has is influenced by several factors, including the planet's mass and its distance from the Sun. Giant planets like Jupiter, Saturn, Uranus, and Neptune have a higher number of moons compared to the terrestrial planets2. This is partly due to their larger gravitational fields, which allow them to capture more natural satellites.
Comparison with Other Planets
While Jupiter leads with the highest number of moons, other giant planets also have significant moon counts. Saturn, for instance, is known for its large number of moons, including Titan, which is the second-largest moon in the solar system2. However, none of these planets surpass Jupiter in terms of the sheer number of natural satellites.
Conclusion
Jupiter is the planet with the most moons in our solar system, boasting a total of 39 known moons. This high number is a result of its massive size and strong gravitational pull, which enables it to capture and retain a large number of natural satellites. The recent discovery of additional moons further cements Jupiter's position as the planet with the most moons.

Moon-packing around an Earth-mass Planet
The maximum number of moons that can stably orbit an Earth-mass planet depends on the assumed masses of the satellites, with up to 7 Ceres-mass, 4 Pluto-mass, and 3 Luna-mass moons possible.
Trajectories of a spacecraft aiming to approach at a near-regular cadence of the Enceladus and Dione moons
This study evaluates strategic trajectories for an artificial satellite to approach Dione and Enceladus at near-regular cadence, considering the gravitational potential of Saturn and the 13 largest moons.
Can moons have moons?
Submoons can survive only around large, wide-separation orbits, with few exceptions, such as Saturn's moons and Earth's Moon.
Looking for planetary moons in the spectra of distant Jupiters.
Future space observatories could detect Earth-sized moons on Jupiter-sized planets by detecting their near-infrared spectral contrast, which could reveal potential habitats for life.
Discovery of five irregular moons of Neptune
Five irregular moons with diameters of 30 to 50 km have been discovered, indicating that Neptune may have captured these moons from heliocentric orbits.
Resonant interactions and chaotic rotation of Pluto’s small moons
Pluto's small moons Styx, Nix, and Hydra are tied together by a three-body resonance, but perturbations by other bodies inject chaos into this stable configuration.
