Got a friend who is a bit of a alien conspiracy nut. Shortly before Moonfall he started with the hollow moon alien base theory (I was laughing tears when I saw the trailer). He said the moon is the only satellite in our solar system that doesn’t rotate and that is proof.

You should have seen his face when I demonstrated with a phone and a bottle of beer that the moon does indeed rotate once every full orbit. It got even better when I explained that one day we will loose the moon cause it very slowly drifts away from us.

I can recommend Heimdall as a quick scratch for that itch. Not big on monitoring, but a great landing page for almost no effort.
