The Moon’s Wobble has been identified by NASA as a potential issue in the near future.
About the Moon’s Wobble:
When the moon orbits an elliptical orbit, its speed changes, causing our view of the “bright side” to appear at a slightly different angle. This is the so-called Moon’s wobble, or this is how it looks in our eyes
It is a regular swaying (Oscillation) in the moon’s orbit, as well as a cyclical shift of the moon’s orbit.
