The Moon is a very slightly scalene ellipsoid due to tidal stretching, with its long axis displaced 30° from facing the Earth, due to gravitational anomalies from impact basins. Its shape is more elongated than current tidal forces can account for. This ''fossil bulge'' indicates that the Moon solidified when it orbited at half its current distance to the Earth, and that it is now too cold for its shape to restore

Does the moon face Earth all the time?

The Moon is rotating at the same rate that it revolves around Earth (called synchronous rotation), so the same hemisphere faces Earth all the time. Some people call the far side – the hemisphere we never see from Earth – the "dark side" but that''s misleading. As the Moon orbits Earth, different parts are in sunlight or darkness at different times.
