Everything You Need to Know About Io | Jupiter's Moon

Welcome to Io, Jupiter's volcanic wonder and one of the most geologically active moons in our solar system. Discovered by Galileo Galilei on January 7, 1610, Io, along with Europa, Ganymede, and Callisto, forms the Galilean moons. With a diameter of 3,642 kilometers, Io orbits Jupiter every 1.77 days at a distance of 421,700 kilometers.

Io's surface is a dynamic landscape of erupting volcanoes, flowing lava, and sulfur deposits, creating a vibrant mosaic of yellow, red, white, and black. The average temperature is minus 143 degrees Celsius, though it can soar near active volcanoes.

Home to over 400 active volcanoes, Io is the most volcanically active body in the solar system. This activity is driven by tidal heating from Jupiter and its neighboring moons, flexing Io’s interior and generating heat. Loki Patera, a 200-kilometer-wide lava lake, and Pele, with its plumes reaching 300 kilometers high, are among Io's most notable features.

Io’s extremely thin atmosphere, primarily sulfur dioxide, interacts with Jupiter’s magnetic field, creating intense auroras. Future missions, such as NASA's Europa Clipper, aim to further explore Io’s volcanic activity and its interaction with Jupiter’s magnetosphere, promising new insights into this fiery moon's secrets.
