Here's an even better version. I fixed the proportions as good as I could do it with an equation I made up and I made the orbit of the Moon going around the Earth and Sun close to real life compared to the Earth going around the Sun.

Hi Ken,
I reversed the coloring so spheres get darker as you approach the outer edge, not lighter, looks more like sheres instead of vacuum holes (have you seen any? LOL )

Yup. definetly possible to shove that into that code.

Wow now they actually look like marbles in space! Thanks B+! I added a starfield around them but that's all I can do for now. I wouldn't know where to start on the crescents, etc. because of the way the Sun always changes angles as well as the Earth. So anyway, here is one with a starfield and the fixed orbs, thanks again. Feel free to add anything you wish to it guys.

I had to fix an annoying problem I had where one side (sometimes both sides) had the Moon go completely in front of Earth on one orbit through the entire year. So I finally found a fix for it. 
Code deleted: Made a new problem.. lol
