Inside the Roche limit (1.79 planet radii): torn apart into a ring system.
Merged with an adjacent moon: too close for both to hold a stable orbit.
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, 56/100).
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
