Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Tidal flexing melts its interior: an actively volcanic surface (Io-like).
Small and distant: a quiet, stable companion.
Cold enough for nitrogen and methane to lie as frost on the surface (Triton-like).
Inside the Roche limit (2.80 planet radii): torn apart into a ring system.
