Could I make a few? I won't do planets; you probably have that covered, but the series says 'celestial bodies'...

What ones did you have in mind? I probably would eventually get to planetoids and moons of our Solar System, but there’s a lot to get through. Even if I make them eventually it’s not a big deal since we’d have different questions and styles of questions.

I was thinking dwarf planets or maybe some of the TNOs, even exoplanets though I doubt anyone would take those. Oh well

Sure, go for it. I will make a Pluto quiz and then probably start on the major moons and such. Again, no worries if there’s a little overlap. 🫡
