Why we only see one face of the moon
It's actually very common for a moon to show only one face to its planet, thanks to [tidal locking](_URL_0_). The force of gravity causes the moon to bulge slightly on the axis pointing at its planet. Over time, this changes the speed of rotation so that the bulge remains in the same place on the…
The Short Answer
It's actually very common for a moon to show only one face to its planet, thanks to [tidal locking](_URL_0_). The force of gravity causes the moon to bulge slightly on the axis pointing at its planet. Over time, this changes the speed of rotation so that the bulge remains in the same place on the moon, with the end result that the same side faces its planet at all times.
