Questions tagged [tidally-locked]
Identifies questions about tidally-locked celestial objects, such as a moon orbiting a planet or a planet orbiting a star. A tidally-locked celestial object rotates once per orbit, always keeping the same face toward the object that holds the lock. Questions may address the physics and consequences of a tidal lock and are not limited to individual dominant-subservient relationships.
