List of largest lakes and seas in the Solar System
Following are the largest lakes and seas on various worlds in the Solar System. Listed are single bodies of water or other liquid on or near the surface of a solid body (terrestrial planet, planetoid, or moon). All objects in this list are expected to be round, hence anything that is part of a belt or disc is expected to be a dwarf planet.
Cold surface oceans or lakes are found on two worlds, Earth and Saturn's moon Titan. Lava lakes are found on Earth and Jupiter's moon Io. Subsurface oceans or seas occur on the other Galilean moons of Jupiter, Saturn's moons Titan and Enceladus, and are suspected on the some of Saturn's other moons, the asteroid Ceres, the larger trans-Neptunian objects, and ice planets in planetary systems. Recent analysis of the interior of Ganymede, taking into account the effects of salt, suggests that it and some of the other icy bodies may not have a single interior global ocean but several stacked ones, separated by different phases of ice, with the lowest liquid layer adjacent to the rocky mantle below.[1][2]
