Similar to Jupitor, or Neptune with their large satellites, but closer to their star.
Large Jupitor sized planets have been discovered that are very close to their stars.
Perhaps there are some that exist at proper life bearing zones from stars.
I realise that such a satellite probably shouldn't orbit too close to its planet, or else it would suffer destructive forces from the large planet. For instance, satellites of Jupitor are wracked with Jupitor's magnetic fields and radiations.
