Thread: What if the moons of gas giants where closer?

What would you suppose would happen if Europa and Titan respectively were put in the same habitable zone orbit as Earth, what would happen to these objects (would titan and europa now be classed as a planets?) and what would happen to the moons geologically?

Well, Wikipedia has a better answer.

Hmm, i'd say Titan would have surface water, then it would be sunblasted right off, as his core is not liquid, and not heavy enough to sustain a magnetic field.

Europa is slightly different, as it's core is heavy, but it's ice will mostly melt, will be covered in ocean, but as his size, and lack of magnetic field will make him look like mars very soon. Though smaller..

I don't know if they would be classed as planets... But mercury is, so they probably would be. They are almost the same size anyway..
