[vtkusers] Planet sized objects and distances on the scale of the Solar System

[Dan Lipsa]

I would look at the the difference between sun diameter and the planets (if
you show the sun on the screen a planet would be smaller than a pixel).
Also, the distance between planets might be so big that if you want to show
that on the screen, planets would be too small to be seen. I have not look
at the actual distances, but this might be some of what you are seeing.

I would start with smaller ratios between sun vs planets and distances
between planets versus planet diameters. After everyting works as expected,
you can move toward the real distances.
