Stars and Planets Simulator

Shape the cosmos in Stars and Planets Simulator, a next-generation space simulator sandbox where creation meets exploration. Forge your own star systems from scratch: design radiant stars, swirling magnetars, enigmatic pulsars, and colossal black holes. Craft both terrestrial worlds and massive gas giants, sculpting their atmospheres, terrains, liquid oceans, or molten cores.

Seamlessly switch from creator to explorer by piloting your fully customizable spaceship across the universe you designed. Land on your planets, step out with your personalized character, and walk the surfaces you imagined — from rocky wastelands to lush alien landscapes.

Gas giants aren’t just clouds; dive deep into their immense atmospheres, maneuvering through stormy skies and dense, liquid metallic oceans, until you reach the solid heart hidden beneath. Every planet, every star, every swirling cosmic phenomenon you encounter is born from your imagination — and ready for you to experience firsthand.

The universe is yours to build, shape, and discover.
