Bill Nye the Science Guy did a great "imagine the Solar System" program
last week with the sun and close in planets in a hockey rink, and
farther out planets in the parking lot, a car dealership showroom,
and Pluto seven hours away from the sun, and as big as a pea.  Made
sense to MY 8 year old.  You solar system people ought to get the
clip.  Diane Brenner, [log in to unmask]
