Spoiler! I was giving our math challenged friend an opportunity to work that out.
Yeah, thanks... But thank you, Johnny, for working it out for me.

And quite coincidentally, I'm sure, 0.5° is almost exactly how "wide" the Moon appears in Earth's skies! (PS - I suspect Ann is not nearly so "math challenged" as she claims.)
Of course, there's a big difference between an angular size of 0.5° on the sky and 0.5° of rotation.

Well, groan - I might have worked it out, but it would have required a lot of effort on my part, and it wouldn't give me that much satisfaction. Yes, some satisfaction, but not enough to be worth the effort.
And Johnny, as I'm writing this, you have 2997 posts. That number immediately rang an NGC bell with me, because NGC 2997 is a very handsome galaxy indeed! So here you are, Johnny, today NGC 2997 is yours - at least until you make another post!

Thanks! To match my handsome physiognomy I'm sure.
