Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal braking locked the planet to its moon: one face forever moonward.
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 100/100).
Small and distant: a quiet, stable companion.
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Inside the Roche limit (1.79 planet radii): torn apart into a ring system.
