If you've explored the included simulations and created some custom systems and now don't know what to do, try to think of a 'What if.' experiment. For example, in the default Solar System simulation, increase the mass of the Sun and see how it increases its gravitational influence and pulls in the planets. Try changing a property and seeing how it affects your simulation. To view properties for any object, right-click on it, or click on it once and then click on its mini-info panel on the right side.

Universe Sandbox allows viewing and editing dozens of properties for every object in a simulation. Learn more in the Add Tool tutorial: Home > Tutorials > Add Tool Next, try adding moons, rings, and asteroids. Your planet will automatically begin orbiting your star.

Click in the simulation to add your star.

Open the Add tool from the Tools menu in the bottom bar, and select a star.

Select Home > New to load an empty simulation.

Here's a simple list of steps to get you started: You can filter the list by selecting a category, such as Collisions, Explosions, Historical, Exoplanets, and Galaxies.Ĭustom simulations can be very simple or very complex, and can vary widely, but a good place to start by with creating your own star system. Go to Home > Open to browse a list of included simulations. Universe Sandbox includes hundreds of built-in simulations to explore. These will show you the basics of the interface, introduce you to various tools and settings, and give you some ideas for starting your journey of astronomical creation and destruction.
