I bought this “game” on Steam for like 3 bucks. It’s called Universe Sandbox. Basically it’s a simulator. Aside from allowing you to watch all the orbits, zoom in/out etc, you can mess around with stuff. Here I added a ton of extra Jupiters to the vicinity of Earth’s orbit

They soon throw earth out of its orbit

What if all the small planets orbited earth

Screw up Saturn’s rings by adding Earth as a moon

Crash some galaxies together

Simulation to show how close Apophis will pass to the Earth

The La Grange points:

A very large star compared to our star:

Very cool.
