Io's volcanoes erupt from tidal heating
Jupiter's moon Io boasts over 400 active volcanoes, fueled by intense tidal heating from gravitational forces, making it the solar system's most volcanically active body.
Jupiter's moon Io is the most volcanically active body in our solar system, with over 400 active volcanoes. These eruptions are fueled not by a molten core, but by intense tidal heating. Io is locked in a gravitational dance with Jupiter and its neighboring moons, causing it to constantly flex and stretch. This friction generates extreme internal heat.
