Io or Jupiter I
Most geologically active object in the Solar System
- Io is the most geologically active object in the Solar System.
- This extreme geologic activity is the result of tidal heating from friction generated within Io’s interior as it is pulled between Jupiter and the other Galilean moons—Europa, Ganymede and Callisto.
Io or Jupiter I
- Highest density of any moon,
- Strongest surface gravity of any moon
- Lowest amount of water (by atomic ratio) of any known astronomical object in the Solar System.
