Peter,
Using your math skill can you give me a scale example of that size? That is, for example; "if Arcturus were 1 mile away it would appear to be 1/16" of an inch in diameter".
What do you think?
Thanks,
Sam
Arturus is 36.7 light years (3.472 x 10^14 kilometers) from Earth and has a radius of 1.767 x 10^7 kilometers, which I work out to be a semidiameter of 0.013".
