Europa's surface is mostly water ice, and the icy crust is believed to hide a subsurface ocean of liquid water. Europa is thought to have twice water as Earth. Europa is one of the places that catch scientists' attention because of the potential for hosting life

Io is the most volcanically active body in the solar system. As it's the inner most moon of Jupiter, immense gravity
causes tides in Io’s surface 100 meters high, give rise to the volcanic activity. Its
surface is covered by sulfur and lava in many colorful forms.

3) 𝗖𝗔𝗟𝗟𝗜𝗦𝗧𝗢:

Callisto has an icy surface covered by craters of various shapes and sizes. Scientists think the bright areas are ice and the darker patches are areas where the ice has eroded. Callisto is a dead moon and craters on moon are believed to be million years old.

4) 𝗚𝗔𝗡𝗬𝗠𝗘𝗗𝗘:

Ganymede is the largest moon in the solar system even larger than the planet Mercury and the dwarf planet pluto, and is the only moon known to have its own internally generated magnetic field and atmospheric auroras.
