Just click the green flag! The simulation will play itself. The button in the bottom left resets the simulation, (it plays a pretty loud sound, beware! :o) and the tab on the right is for school stuff, you can just ignore it. Unless you're my science teacher. Then you should probably click on it.
This project is for my science class! It's just a little simulation, that isn't to scale planet size, distance, or orbit speed wise. (I'm not THAT good :P) There is a little red dot, which is my "telescope" which I sent to take pictures of three planets in this order: Jupiter, Mars, then finally Venus! (I named it voyager lll cuz why not :P) Anyways, Enjoy!
