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.
Io (Jupiter I) is the innermost of the four Galilean moons of Jupiter; with a diameter of 3642 kilometers, it is the fourth-largest moon in the Solar System, and is only marginally larger than Earth's moon. It was named after Io, a priestess of Hera who became one of the lovers of Zeus. It was referred to as "Jupiter I", or "The first satellite ...
While processing images of Io to enhance the visibility of background stars, navigation engineer Linda Morabito found a 300-kilometer (190 mi) tall cloud along the moon's limb. [54] At first, she suspected the cloud to be a moon behind Io, but no suitably sized body would have been in that location.

Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
The Chinese government has a released a series of stunning high definition images taken from space by a state-of-the-art satellite. China's Gaofen-1 satellite was launched in April 2013.
Io's shape changes as it completes its orbit. (C) Earth's moon's orbit is actually more eccentric than Io's, but Earth's gravity is much weaker than Jupiter's, so Earth's moon does not experience as much deformation. [1] Tidal heating of Io (also known as tidal working) occurs through the tidal friction processes between Jupiter and its moon ...
