@shallow-blue saidI also read in several places that it due to the moon having a thicker crust on the far side. Must have been in its early life though as it’s completely solid now isn’t it?
Not a mystery at all. The moon is tidally locked to the earth but hasn't always been. Thus, the near side still bears the scars of the time when there were still relatively big asteroids in our orbit to make nice big craters there, while on the far side they have been obliterated over time by a continuous barrage of smaller but more common bodies.
