Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (9/100).
Inside the Roche limit (1.79 planet radii): torn apart into a ring system.
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Small and distant: a quiet, stable companion.
