The Moon’s apparent size changes slightly, though, and a slight wobble called a libration is discernible as it progresses along its elliptical orbit.
There is so much our brains can no comprehend on their own. Here is an example of how photography expands knowledge. I had never seen this before. Looking at the moon each night, I can not perceive the slight changes as shown in this little animated GIF. This is one of the advances that photography has brought to our understanding of our environment. This reminds me of a podcast Brooks Jensen made where he pointed out that it has only been a couple of hundred years since the development of photography, before which there was no photography at all, to now where millions, tens of millions, maybe hundreds of millions photographs are taken each day.
