- Ganymede: Bigger than the planet Mercury, the largest moon in the solar system contains subsurface oceans that could be capable of supporting life.
- Titan: The second largest moon in the solar system and the only celestial body other than Earth to have both a substantial atmosphere and bodies of surface water.
- Io: This moon of Jupiter is so full of volcanos that it is the most geologically active and lowest water ratio object in the solar system.
- Callisto: May be the oldest surface in the solar system. With a thin atmosphere and no geothermal activity its surface is defined by the many impact craters it has accumulated over time.
- Europa: The smallest moon of Jupiter contains a subsurface layer of saltwater ocean that could also support life. It also has plumes of water that are several miles high.
- Mimas: This moon of Saturn has a massive crater that makes it look like the Death Star from Star Wars.<|im_end|>
