Adding moon to rotate around the Earth

[barrychc]

Hi @darknessomi,

First of all, thanks for sharing this awesome project.

I am a new learner of Unity and would like to add the Moon rotating around the Earth in this solar system. I've tried a few ways modifying Rotate.cs and Populate.cs without success. Do you think this is possible? If so, would you please give me some hints?

Thanks very much.
