Question

Quizplus · Accepted Answer

Io and Europa are the moons around Jupiter known to have associated plasma tori. Io, in particular, is the most significant source of plasma in the Jovian magnetosphere, primarily due to its volcanic activity which releases sulfur dioxide gas into space. Europa, while less significant than Io, also contributes to the plasma environment around Jupiter. Ganymede and Callisto have not been observed to have similar plasma tori.
