QUOTE : Red dwarf systems have a tendency toward tidal locking – a state in which an object’s rotational period is the same length of time as its orbital period. To illustrate this more simply: think about the way our Moon looks from Earth. When looking up at a full Moon on a clear night, you will always see the same friendly arrangement of craters shining back. Some cultures see a face in the Moon; others, a rabbit. Whatever the interpretation, the underlying truth remains the same. One side of the Moon is always facing Earth. The far side never does.
