Explore the names and provisional designations of additional natural satellites. The giant planets have many tiny, faint moons—often only a few kilometers wide—and most have no detailed photographs. The lists below are a curated directory, rather than a complete name-by-name registry of all 456 known moons. You can browse the full current NASA/JPL satellite registry for the complete list.
Moon counts: NASA Space Place and Saturn Moons (2026). Other moon facts: NASA Solar System Exploration. For the Moon, Io, Europa, Ganymede, Callisto, Titan and Triton, the interactive viewer loads spacecraft-derived image maps when online. Offline and other moons use labeled artistic surface models, not direct photographs.
