Ganymede and Callisto
i've got to write an essay on Jupiter's Galilean moons, with a page or so on each one. Io is easy - unique for its volcanism. loads to say. And Europa too - with its ice surface and ocean below. but what about Ganymede and Callisto? they seem boring compared to the other two. what can i say about them? anyone know anything that I don't?

Ganymede also has it's own magnetic field, independent of the one that Jupiter would impose on it. Both Ganymede and Callisto, may also have subsurface oceans, like Europa.

Far from being boring, each body in the solar system is unique in its characteristics, while sharing many things as well. Io and Europa certainly have the spotlight in the media, but the other satellites have surface and internal features that are just as interesting, and puzzling. You'll find this true even of "common" objects like asteroids and comets...they always have something of their own that makes them worth studying.
