Inside the Roche limit (1.79 planet radii): torn apart into a ring system.
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
Inside the synchronous orbit: it spiraled inward and was torn apart at the Roche limit (Phobos's fate).
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 (25/100).
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).
Small and distant: a quiet, stable companion.
