I've been thinking of a setting on a tidally locked outer moon world of a mini star system orbiting in a larger star system. It distance makes the dayside habitable with constant sunlight. At least four other moons orbit this star as well. I was wondering if there can be a similar day/night cycle to earth by one or more of the other moons eclipsing the star during their orbit? I was thinking of a larger moon on an elliptical orbit that syncs up with this world half way during it's orbit.
