One neat feature of living on the Moon is that the Earth is always in the same place in the sky.

You have heard of libration, right? The Moon exhibits both latitudinal and longitudinal libration - hence, an observer on about 1% of the surface of the Moon (i.e., at the so-called "limbs" at the apparent edge of the Moon as viewed from Earth) could watch the Earth completely dipping below / rising above the lunar horizon every month.

For observers elsewhere, the libration is still in effect, but the phenomenon wouldn't be as dramatic - the Earth would simply appear to wobble about 8° (due to longitudinal libration) and 7% (due to latitudinal libration), and therefore describe an analemma in the lunar sky.

The Earth has an apparent diameter of about 2° in the lunar sky, so this shift in position is not trivial.

I was aware of this wobble but figured it wasn't very much. Thanks for the update.
