17. mind-boggling that we can see something at that distanse.

< o

= you and your eyes
< equals the line of site
o = Moon

< o = you looking at the moon and the cone of vision starting at your pupil and going to the edges of the moon.

If you look at the moon, you at the small end of this angle, and the moon at the open side;
the moon, at about 3 feet from your eye would be about 12" across.

If you put that closest star at the open side, how large would it be at 3 feet from your eyes?

If you have that answer, great! I'd love to know. I think it will be, for most of us, a mind-boggling answer.
