Inspired by planets to scale, customizable version with the added benefit that you can view the scale of sun and planets in 3d.
I have also added the moon and Pluto etc and the spheres are hollow.
The real distances between the sun and planets is in the file and can be substituted for the print distances. This is represented accurately in openscad but due to the vastness of space will be impossible to see (unless you change the size of the planets to make them visible).
