Question

Quizplus · Accepted Answer

Io is known for its intense volcanic activity, with over 400 active volcanoes and plumes. It is not the largest moon in the solar system, that title goes to Ganymede. There is no evidence to suggest a deep subsurface ocean on Io, and it does have a very thin atmosphere, but it is not the only moon with an atmosphere.
