About this app

Create your own solar system in the outer space with Galaxy Space Simulator 3D for FREE! 🪐 Add new planets šŸŒ, moons 🌘, stars ā­ļø, and asteroids. ā˜„ļø The universe sandbox is an addicting 3D space simulator based on realistic astrophysics. You will see how gravity will create the planet orbits and how galaxies or star systems like Milky Way Galaxy or Alpha Centauri form. šŸ’« This is a perfect game for astronomy and science fiction lovers. šŸ”­

Interstellar space exploration may not be possible for now, but that doesn’t mean we can’t imagine creating our own solar system on the outerspace. šŸŒ’ Perhaps your solar system is located at Milky Way Galaxy, or perhaps Alpha Centauri or other galaxies not visible even with the strongest telescopes. Through this realistic simulator that follows the astrophysics law, you can see how the planet orbit forms and follow its track, and you can see how asteroids build up the asteroid galaxy. Unlock more planets for FREE through achievements. Galaxy Space Simulator 3D is such an educative, fun, and exciting astronomy simulator app!

it's a fun way to pass time, it would be nice if I could put more planets without having to buy that ability. at least you can unlock a few planet spaces through achievements but still it's annoying to have to have to do all that just to add a few planets. all in all it is a fun game to mess around with though, it would be cool if there were a few new options to fool around with but anyway thanks for a good game.

this is good for space simulations but the controls are confusing and there's not much freedom and we can only make planets and stars, low quality also, not what I expected as like a good one like search engine but good overall and completely free which is the good part, thanks 😊

I unlocked everything after playing around for a few days. All bad reviews I've read are either overlooking simple options which solve the problem, or expect a phone app to behave like a high-end PC. There are easy options to create stable circular orbits. Parabolic orbits used to be impossible, but now realistic mode makes it a reality! For all the astronomy fans out there, this really is as close as it gets to a real 3d space engine on a mobile device.
