If you're referring to the outdoor setup by the Air and Space Museum,
it most certainly *is* to scale. Both the planets and the distances
between them. It really gives a sense of how much larger the
distances between the planets are than the sizes of the planets.
There was a guy at some con we went to once ... the kids were
tinies, so it may have been MidAmeriCon. Anyway, he had a ball a
foot in diameter, done up as a globe of the earth, and another
one rather smaller, done up as a globe of the moon. They were to
scale. He hung out in a long corridor in the convention center,
inviting people to take the moon globe and put it at the proper
distance from the earth globe.
Hal was one of the few people who got it right. Thirty earth
diameters, IIRC.
And I think it was after that that his sister Andrea did a piece
of artwork. In needlepoint. On a very long narrow canvas. At
one end was an image of the earth, at the other, an image of the
moon. The two bodies, and the distance between them, were to
scale. In the middle, not to scale, was a representation of the
Apollo 13 capsule. Title: "Cliffhanger."
I haven't seen it in years. It's difficult, of course, to find a
place to display it. I don't know if she has it up in her house
in Portland, where I've never been.
