Document Summary
All four jovian planets have extensive moon systems, and more are continually being discovered. We split them into 3 groups based on diameter: large = over 2500 km: medium = 400 1600 km small = less than 300 km. The formation of jupiter and its moons may have mimicked on a small scale the formation of the sun and inner planets. Io is the most innermost of jupiter"s moons, and the most geologically active object in the solar system. It has many active volcanoes, some quite large (more than 80 identified). Io can change surface features in a few weeks. Io has very few craters as they fill in too fast io has the youngest surface of any solar system. Io is very close to jupiter, and also experiences gravitational forces from. The tidal forces are huge, and provide the energy for the volcanoes. Europa has few craters; surface is water ice, possible with liquid water below.
