Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).

Small and distant: a quiet, stable companion.
Tidal braking locked the planet to its moon: one face forever moonward.
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (12/100).

Outside the synchronous orbit: slowly receding, like Luna (~cm per year).
A thin tidal-warmed subsurface ocean may exist, but conditions are marginal (21/100).
Merged with an adjacent moon: too close for both to hold a stable orbit.
