As the below graph demonstrates, the absolute magnitude (total inherent brightness, abbreviated H) of moons we have detected around planets peaks at H = 17 for Jupiter, H = 16 for Saturn, H = 13 for Uranus, and H = 11 for Neptune. Smaller moons may (and most likely do) exist around each of these planets, but are currently undetectable from Earth. Although spacecraft have visited all of these planets, Earth-based telescopes continue to outperform them in moon-detection ability due to their greater availability for wide-field surveys. List This is a list of the recognized moons of the planets and of the largest potential dwarf planets of the Solar System, ordered by their official Roman numeral designations. Moons that do not yet have official Roman numeral designations (because their orbits are not yet known well enough) are listed after those that do. The 20 moons that are known to be large enough to have been rounded by their own gravity are listed in bold. The seven largest moons, which are larger than any of the known dwarf planets, are listed in bold and italic. Sidereal period differs from semi-major axis because a moon's speed depends both on the mass of its primary and its distance from it. See also References
