A volcanologist's paradise

Io and Jupiter

422,000 kilometers (262,000 miles) away from Jupiter, Io is a fascinating site for those who can't stand a stable life. Sulfur dioxide is in abundance, and any impact crater can be filled with molten lava anytime.

Named after a mortal woman transformed into a cow by Jupiter's wife Juno in Roman mythology, there is a lot to explore on Io for those who dare.
