Io orbits Jupiter at a distance of 421,700 km (262,000 mi) from Jupiter's center and 350,000 km (217,000 mi) from its cloudtops. It is the innermost of the Galilean satellites of Jupiter, its orbit lying between those of Thebe and Europa. Including Jupiter's inner satellites, Io is the fifth moon out from Jupiter.
Jupiter's moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high.
1 day ago · Using its JIRAM infrared instrument, NASA's Juno spacecraft has imaged lava lakes across the surface of Jupiter's moon Io. The images give researchers insight into Io's volcanic activity.
Jupiter's rocky moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains dozens of miles (or kilometers) high.
4 days ago · Io has intrigued the astronomers since 1610, when Galileo Galilei first discovered the Jovian moon, which is slightly larger than Earth’s Moon. Some 369 years later, NASA’s Voyager 1 spacecraft captured a volcanic eruption on the moon. Subsequent missions to Jupiter, with more Io flybys, discovered additional plumes — along with lava lakes.
Apr 18, 2024 · 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. A...
4 days ago · The JunoCam instrument aboard NASA’s Juno spacecraft captured two volcanic plumes rising above the horizon of Jupiter’s moon Io. The image was taken Feb. 3 from a distance of about 2,400 miles ...
Dec 27, 2023 · The orbiter has performed 56 flybys of Jupiter and documented close encounters with three of the gas giant’s four largest moons. NASA’s Juno spacecraft will on Saturday, Dec. 30, make the closest flyby of Jupiter’s moon Io that any spacecraft has made in over 20 years.
Io is the innermost of Jupiter’s four largest moons, which are also known as the Galilean moons (Europa, Ganymede, and Callisto are the remaining three). Because it’s the closest moon to its massive host planet, Io feels a strong gravitational pull as it orbits Jupiter.
Jun 8, 2024 · Io, innermost of the four large moons (Galilean satellites) discovered around Jupiter by the Italian astronomer Galileo in 1610. It is the most volcanically active body in the solar system. As many as 300 volcanoes may be active on the satellite at a given time.
