Io is probably one of the most well-known moons in the solar system. Orbiting 422,000 kilometers above Jupiter, Io is the innermost of the four Galilean moons. Io, along with the other three ...

Distance from Jupiter: Io is the fifth moon from Jupiter. Its average orbital distance is about 262,000 miles (422,000 km). Io takes 1.77 Earth -days to orbit Jupiter.

The Io–Jupiter system is similar, in scale, to an exoplanet orbiting an M-dwarf, and if volcanic Io doesn't have a magma ocean then perhaps exoplanets on close orbits around M-dwarfs don't either.

Jupiter's moon Io is a volcanic hellscape—and has been since the solar system began. Io is the most volcanic body known to science, and researchers have puzzled over its history for years.

Io, the innermost of Jupiter's four largest moons, is slightly bigger than Earth's moon.Io is the most volcanically active body in the solar system, bursting with plumes that rise up to more than ...

image: As the Cassini spacecraft gets closer to Jupiter, details heretofore not noticed are becoming obvious. The Great Red Spot, which only a week or two earlier appeared to lack features, is now ...

Jupiter moon of Io is famed for its volcanoes. NASA just spotted the most powerful one yet Not only was the hot spot larger than Earth’s Lake Superior, but it also was seen belching out ...

The mutilated surface of Jupiter’s moon Io was revealed in great detail by the Juno spacecraft, which has been exploring the Jovian system since 2016 and recently pulled off the closest flyby of ...

What can a sample return mission from Jupiter's volcanic moon, Io, teach scientists about planetary and satellite (moon) formation and evolution? This is what a recent study presented at the 56th ...

Io's volcanic processes are poorly understood because we don't have long-term continual observations of the moon, Marchis said. Even when the Galileo spacecraftorbited Jupiter and its moons ...

Jupiter’s moon Io may have been volcanically active throughout its life. In this image of Io, taken by NASA’s Juno spacecraft in 2023, a bright volcanic plume can be seen on the left, just ...

Jupiter's third-largest moon, Io, is the most volcanically active body in the solar system, as confirmed by the longest-running observations of the moon's thermal output. The regular eruptions and ...
