Create your own solar system with our immersive 3D and realistic space simulator for FREE! Galaxy Space Simulator is an immersive, fun, and addicting simulator with base on real astrophysical gravity law. You can watch in real time how a planet orbits the sun and how asteroid belt forms. It’s an educational activity that is so mesmerizing and entertaining for the whole family. === FEATURES OF GALAXY SPACE SIMULATOR: === * IMMERSIVE HIGH QUALITY 3D GRAPHIC Enjoy the immersive, realistic graphic. It really feels like you are in the outer space and observing the solar system from away. This app uses simple swipe and pinch to control the view. You can view the planetary orbits and track them. * FREE SIMULATOR Enjoy our 3D space simulator for FREE! You start with limited planets but you can unlock more by completing achievements. We add new achievements to unlock so you will never run out of things to do and explore. * REALISTIC SIMULATOR The movement of the sky objects are simulated based on how gravity works in the outer space and how each object pulling at each other depending on their mass. You can see how the planet orbits the sun and maybe collides with each other, how asteroid belt forms, and other space phenomenon. * CUSTOMIZATION Customize your planets and stars with textures and skins. You can also change the background of the scene. You can also adjust for speed, size, and location of the sky objects, as well as choose for random distribution. * HOW TO PLAY GUIDE You don’t need to feel overwhelmed. We explain the app control and functions within the app so you know how to create sky objects, follow the orbits, view guide, and more. * SAVE, LOAD, PAUSE AND RESUME You don’t have to worry of losing your solar system if you can’t finish it in one go. Save your project and load it later on. You can also pause and resume the solar system anytime. * SHARE ONLINE Do you want to impress your friends and family with your creation? Share your creation on social media. You can also share your solar system model with other users, find models by other users and modify them to create your own. You don’t have to be a sky gazer or a science fiction enthusiast to enjoy our space simulator app. This is a very fun and addicting activity to do anytime, anywhere. Don’t worry if you don’t know where or how to start. You can load other people’s solar systems and add your own elements to them as you like. Keep creating and experimenting and enjoy watching what will happen as the planets, stars, and asteroids moving and orbiting each other. You can witness planetary collisions and the evolution of the solar system you create as time goes by. It will certainly deepen our understanding about the space and universe. *** We appreciate all the feedback from our users.

Read full description

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict

The call

Galaxy Space Simulator 3D and Solar System Sim both sit at 4.4 stars, but that hides the real split: 80% of Solar System Sim's written reviews are positive against 40% of Galaxy Space Simulator 3D's. Solar System Sim also leads on update cadence (every 3 weeks vs every 5 months) and ratings volume (4.1K vs 457). Galaxy Space Simulator 3D's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, rating, in-app purchases and monetization model there is nothing between them.
