So i was doing the Sun, Earth and Code tutorial. I finished it easily. I decided to take it to the next level, and thats where I need your help. My goal was to make a moon orbit the earth, which is orbiting the sun. I'm very close. I have lined up the moon on the earths orbit, but I'm not sure how to make the moon orbit a moving earth. Here is the link to what I have so far: http://www.codecademy.com/yasgur99/codebits/WScKP3/edit
If someone could please tell me how so i could go on and maybe try to make a moon orbit that moon, I would greatly appreciate it.
