I found myself wondering, "Just what constitutes macro in a photography sense?"

Wikipedia makes some efforts to define it, which I paraphrase and list in no particular order:

An extreme closeup where . . .

1. Subject in finished photo is larger than life.
2. Subject appears larger than life on film, negative or image sensor.
3. Subject appears larger than life on camera display/viewfinder.
4. Made with a lens with a reproduction ratio of at least 1:1.
5. Subject vertical height is 24mm or less.

Clearly, a picture of the sun that is larger than the sun itself will require more than all the monitors to display . . .

I didn't realize there were so many available definitions, but I bet we could get more if we asked around on the internet.

Anyway, I'll do my best with something. Thanks for the challenge.
