Abstract

We now know Io to be a world of superlatives among solar system bodies. It experiences the strongest orbital resonances, exhibits the greatest volcanic activity, sustains the most rapidly escaping atmosphere, and lies deep within the most powerful magnetosphere. This chapter synopsizes the centuries of studies that revealed Io’s remarkable properties, but highlights how the fundamental interconnectedness between these distinct properties were revealed only in recent decades. In fact, the revelation of links between seemingly unrelated planetary phenomena placed Io in the position to revolutionize planetary science. Before Io, who might have hypothesized that orbital peculiarities could drive volcanoes, shrink moons and power aurora? Io’s example forces planets and moons to be studied as coupled as systems, from celestial mechanics through interiors, surfaces, and atmospheres to magnetospheres.
