The Moon |

I was musing this evening.
The moon's day and year are both the same length. Thus it always presents the same side to the earth. This quirk probably held back ancient astronomy by several thousand years as something as obvious as a rotating ball in the sky is something of a give away. The odds of this quirk occuring must be astronomical (pun intended. ) And are they exactly the same length? Or is the moon very slowly turning on us?

An interesting side effect of this day = year scenario is that only the side facing the earth has Mares (seas). These are lava flows that occured before the Moon "died". The interesting thing is that the earth's gravity had such a strong effect on the magma flow of the Moon that it brought all erruptions to the closest side.
I would also think it quite probable that this side is the denser side of the Moon.
