Jupiter moon could one day break free

What I wish to know is whether the radius of Io's orbit is shrinking or expanding. If it happens to be shrinking, it may wander so close that the tidal forces will shatter the moon to peices and form a spectacular ring system that can match that of Saturn's. This may also happen to Neptune's moon Triton.

Hi Xammu; But if its orbit is getting larger it could only mean one thing, do i need to elaborate? YES

it will hit the earth on 2012 oh we are doomed!!!

Hi Xammu; But if its orbit is getting larger it could only mean one thing, do i need to elaborate? for example. earths moon, the orbit is getting larger and within a few billion years it will leave earths orbit completely, but by the time that happens the sun wouldve eaten the earth. or you can look at mars, one moon's orbit is getting closer and will eventualy crash into the planet and the other is getting further away and, like our moon, it will leave mars' hold completely (eventualy)
