Moons of the Solar System

The following are some of the Moons of the Solar System scaled to the Earth's moon.

Europa and Ganymede are believed to have liquid water beneath their surfaces. Europa is believed to have a liquid salty ocean and is accessible for exploration as the ice layer is substantially thinner than other moons, allowing access to the ocean. Scientists believe there may be conditions suitable for life in Europa's ocean.
