Within Universe Sandbox, objects are categorized based on their properties, particularly their mass. For performance reasons, not all simulation effects are calculated for each type of object. For example, stellar evolution is not simulated for planets.
The object types in Universe Sandbox include:
- Planets, Moons, and large Solar System Objects
- Fragments (including small Solar System Objects)
- Human-Scale Objects
- Black Holes
- Galaxy Nebulae
- Nova Clouds
