      <Description>Io orbits Jupiter at a distance of 421,700 km from Jupiter's center and 350,000 km 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. It takes Io about 42.5 hours to complete one orbit around Jupiter. Io is in a 2:1 mean-motion orbital resonance with Europa and a 4:1 mean-motion orbital resonance with Ganymede, completing two orbits of Jupiter for every one orbit completed by Europa, and four orbits for every one completed by Ganymede. This resonance helps maintain Io's orbital eccentricity (0.0041), which in turn provides the primary heating source for its geologic activity. Without this forced eccentricity, Io's orbit would circularize through tidal dissipation, leading to a geologically less active world.

Like the other Galilean satellites and the Moon, Io rotates synchronously with its orbital 
period, keeping one face nearly pointed toward Jupiter. This synchronicity provides the 
definition for Io's longitude system. Io's prime meridian intersects the equator at the 
sub-Jovian point. The side of Io that always faces Jupiter is known as the subjovian 
hemisphere, whereas the side that always faces away is known as the antijovian hemisphere. 
The side of Io that always faces in the direction that Io travels in its orbit is known as 
the leading hemisphere, whereas the side that always faces in the opposite direction is known 
as the trailing hemisphere.</Description>
