Io, illustration. Io, the third largest of the moons of the gas giant planet Jupiter, has a diameter of around 3660 kilometres. The gravity of Jupiter and other moons, create huge tides, powering Io's volcanoes and geysers. These can eject sulphur dioxide many kilometres into space. Hundreds of active volcanoes on Io make it the most geologically active body in the solar system.
