If I'm understanding your scenario correctly, you need to factor in the star which allows the satellite to be visible. In my head (given roughly the same orbital planes), I believe, you would need the moon to be geo synchronised with the planet, and the planet to be almost tidally locked to the star (with a rotation period of 1 year, which would make the planet uninhabitable). I don't think mass and distance really matters in this situation specifically though, but I don't have a degree in this.
