Hello!

I'm guessing that you're asking how far each planet has to be from the sun in your model. If so then there is a table with the orbital distances (AKA the distances from the sun) in this PDF, and you can calculate the distances using this formula:

Code: Select all

distance from the sun(in m) = 235m x AU of planet

Quick reminder that it will be a hard to actually make the model because, for example, Neptune would have to be about 7 kilometers away from your sun.

This is a bit more complicated, but if you want to know how the previous formula is created. It's done by creating a table with each planet and their AU, then using cross-multiplication with Earth and the specific planet which makes

Code: Select all

distance from the sun(in m) = (235m x AU of planet)/1

and you can always remove x1 or /1.
