While other locations might hold comparable amounts of water in the form of ice or vapor, none combine such immense volume with free-flowing liquid. Enceladus: This small moon of Saturn ejects water vapor and ice particles from geysers at its south pole, hinting at a subsurface saltwater ocean in contact with rock.
Search For Water Exoplanets: Discovering Water Worlds Beyond Our Solar System
No other known body in the solar system has stable bodies of liquid water covering a significant portion of its surface. While the surface is a smooth crust of ice, scientists strongly believe a global ocean of liquid water lies beneath, kept in a molten state by tidal heating.
Estimates suggest this subsurface ocean could contain twice as much water as all of Earth’s oceans combined. Looking Beyond the Blue Marble To truly answer what planet has the most water , one must look beyond the familiar blue marble.
