Re: Sulfuric Io in True Color . . .
I thought I ordered that without anchovies...sorry.
A moon that has been locked into tidal synchronization with its primary, has a stable orbit, and has one face always pointing towards it, no longer has significant tidal forces working on it. I read somewhere that Io is prevented from such a stable lock by forces acting on its orbit by other moons, and this is why the tidal disruption on Io is so intense.
