What a great example! As a recent astronomy enthusiast, I found myself doubting this comment initially ("well, eclipses ARE related"), and this despite the fact that I have a toy tellurion right by my desk.
But hearing a particular phrase in the below video helped correct my model. One sanity check is that you can see non-full moons during the day (although I definitely would have just assumed it was still a matter of angles).
Side comment: This is the first time I've seen my preferred username used for its actually meaning. And I've been using it for almost 3 decades. Neat.
I was going to use tellurian, which means an inhabitant of the earth, then saw that tellurion was sometimes used as an alternate spelling in an old Webster's dictionary I was looking through, and preferred it.
And yes, I did search through a dictionary to find a username.
