This project was inspired from the book The Tree Body Problem by Liu Cixin

The scale of the size Celestial Bodies is not accurate. They all appear significantly larger than their mass would allow at this scale and even the most massive stars would actually appear as small spots.

This does not solve the N Body Problem. The nature of the problem is that we have yet to develop truly accurate ways of accurately predicting the movements of more than two bodies significantly acting upon each other for extended lengths of time. This is more of a visualization of how gravity effects bodies with extremely broad accuracy. And its fun to try to make pretty systems.

The appearance of each body is based on windows of mass thresholds. If the body has enough mass to form the next body style. For example, if the body has a mass greater than 2.3e27, it has enough mass to begin internal fusion and form a star.
