Love this video! I have a question though, considering both the moon and the earth are rotating and on top of that the earth is also revolving – how do I keep track of where to find the moon on the sky in each different phase, moth, etc…

I wonder what a spinning moon's effect would have been before it became tidally locked with one side always facing the earth. Is there a way to tell how fast it could have been rotating in it's history by looking at very ancient impacts beneath all of the more recent craters?

The reason why I ask, is that the rotating moon may have caused a longer duration to the heavy bombardment, if rocks hitting the moon got kicked up into earth's orbit to impact later that year or even next year when the earth travels through that region of relativistic moving space rocks that could just be 'sitting there' until the earth runs into it.
