Default Orbital traits of Earth vs Moon

The image above is meant to convey a 'rotating moon' but really only displays an orbiting satellite, in this case the LRO.

The traditional narrative is that people argue over whether the Moon rotates or not however the real substance, at least for genuine researchers, is how the Moon behaves differently from the Earth as each travels around their parent central object.

The idea that the Moon also spins as it orbits the Earth is due to a misreading of the awkward phrasing in Kepler's Somnium, this issue has been covered so many times that there is no need to repeat it however the preponderance of the notion is obstructing the appreciation that the Earth actually turns once to the Sun as a function of its orbital motion and pronounced in isolation at the North and South poles which experience a single day/night cycle each orbit as a result of the planet's orbital trait.

So, the point of departure for all issues involved is that as the moon travels around the Earth it does not display all sides of its surface to the central Earth while the Earth traveling around the Sun shows two distinct rotations f the entire surface to the central Sun.
