This simulation shows many massive stars orbiting a much more massive central star.
It was created by making a new simulation, then using the Edit / Add Family... command with the 3D Collapsing Cloud quick setup, and then running the system until it had collapsed about as far as it would go - with most of the stars combined into one large central star, orbited by the remaining stars.
If you set the system running, you can watch how it evolves, and see how the orbits change as the stars interact with each other.
You can create a huge variety of many body systems yourself, using the Edit / Add Family... command with various quick setups, edited in various different ways. You can also create many body systems by adding objects one at a time, rather than by using the Edit / Add Family... command.
