Io in true coor

This strange moon is one of Jupiter's moons, discovered by Galileo. It is Jupiter's largest moon. It's surface is covered  in continuously erupting volcanoes. Some of the lava bursting through it's surface has such a high temperature that it glows in the daark. The many volcanic eruptions on Io's surface is caused by the gravitational pull of Jupiter's surrounding moons as well as Jupiter itself, much like the tidal pull that we experience on Earth. It's surface consists of silicate rock and sulfur.
