How big is Io vs Earth?
Size: Io has a mean radius of 1,131.7 miles, making it slightly larger than Earth’s moon. It has a slight elliptical shape, with its longest axis directed toward Jupiter. Among the Galilean satellites Io ranks third, behind Ganymede and Callisto but ahead of Europa, in both mass and volume.
Can we live on Io?
Io is generally considered a poor candidate for life because of all the radiation Jupiter blasts it with. In addition, no organic molecules have been detected on its surface, and it has only an extremely thin atmosphere devoid of detectable water vapor.
