Very interesting--thanks for sharing, Vince. I'll have to remember some of that the next time I do an outreach educational session for my son's elementary school class.

Thanks. I'm glad you liked it. I had originally thought a golf ball would be the comparison- it just looks kind of like that up there :) - but it was too difficult to find something common enough to keep the proper ratio that would be recognizable.

I walked out a scale solar system (up to Saturn) with my daughter's class years ago. Interestingly, regardless of the scale, if you stand where the scale Earth is, the scale Moon (at the proportional distance) will look the same size as the real Moon!
