It is also the only confirmed satellite to have active volcanoes. Its orbit is in a 1:2:4 resonance with Europa and Ganymede. Io in Orbiter Io was introduced to Orbiter in the Orbiter 2002 release, and each version after that. Io's orbit was governed by the Io.cfg file in Orbiter 2002 and later versions until Orbiter 2005 when Vsop87.dll governed Io's orbit. Io is modeled as a sphere 48806 km in diameter with a mass of 8.93×1022 kg.
