Make your own solar system in minutes! Create planets and change their size, starting speed, color, mass, and even their name. Remake our own solar system, or make a completely different one. Features saving and loading, the ability to make moons, background music, and much more. It may seem confusing at first, but once you get the hang of it it will be very easy to use.
I changed this to incomplete because, well, it is incomplete. I can't believe I missed so much stuff to add.
