Looks innocuous enough at first glance right? Let’s zoom in on the problem:
These don’t go together. If the semicircle on the left is correct, then this is showing moon phases, and the symbol on the right should be of a gibbous moon:
If the cookie-with-a-bite-taken-out in the right is correct, then this is showing an eclipse, and the symbol on the left should be of a 50% partial eclipse:
It drives me crazy every time I look at it.
I see the problem, but I doubt many would. No easy fix, but you could go two directions. Replace the one wrong shape and rearrange them, or just replace one of the open circles with a solid and rearrange them to represent an eclipse (with solid on the outside, hollow in the middle.
I get how an astronomy fan would get annoyed. I’ve gotten gifts before that have had a slight inaccuracy to it, so small I didn’t even catch it the first time I saw it. And now I can’t unsee it. I still appreciated them though. And yes, I had in a few instances considered if I could fix the issue, but sometimes it’s better to just accept it as is. Nothing is perfect, after all.
Eclipses do not have a semicircular phase. It’s wrong as lunar phases, and it’s wrong as an ecliptic transit.
