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).
Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
Tidal heat sustains a subsurface ocean over a rock seafloor: a strong candidate for life (Europa-like, 96/100).
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
