Its orbit generates a current of approximately 3 million amperes in the magnetosphere of the planet it orbits.
Its orbit generates a current of approximately 3 million amperes in the magnetosphere of the planet it orbits. An area of low strength in that planet's magnetic field has led some to believe that this moon has its own magnetic field. Photographs of its Tvashtar region indicated a sapping-like process that occurs presumably with sulfur dioxide. Better known geological features are the so-called collapsing mountains and Loki, the most powerful volcano in the solar system. For ten points, identify this densest and innermost Galilean moon of Jupiter.
