Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
JunoCam successfully returned detailed images of Ganymede after Juno's flyby on June 7, 2021, [6] with further opportunities including planned flybys of Europa on September 29, 2022, and two of Io scheduled for December 30, 2023 and February 3, 2024. These flybys will also reduce Juno's orbital period to 33 days. [7]
