I'm trying to picture life on a planet sized moon of a huge planet in a one-star stellar system. It would be tidally locked, which could do some interesting things. It has an iron/nickel core for the magnetosphere, and a similar surface to earth. It has tectonic activity, and I'm hoping that I can put some cryovolcanoes or whatever they are called. There are going to be long days, full of huge solar eclipses. temperature might be strange. I'm sure that I'm forgetting a lot of things.
Question: Is this possible?
