If you had the power, how would you create the solar system? What would be the size of each planet or star? And how would you place them in orbit? If you are interested in Astronomy and looking for a powerful yet easy to use 3 dimensional space sand box app to create and simulate a whole new galaxy with realistic physics rules, then you’ve come to the right place. Orbit Sandbox Universe, the 3D sand box game, provides you the ultimate power to explore the infinite space and simulate your own space full of different planets, gas giants, and stars.

In this gravity simulator app, you get to customize literally any aspect of these particles to simulate and design your very own solar system in this sand box. Once you are satisfied with your customized solar system (or any other combination of particles, planets, and stars), you get to easily add it to your collection, take a screenshot and share it with the world.
The game comes with a clean and neat design and the 3D simulation is so smooth that you won’t feel any difficulties or lags when bombarding your planets, or applying any condition to them. And make sure not to take the realistic gravity lensing effect as granted when looking at a black hole. It’s just fascinating.

Is this Orbit Sandbox Easy to Use?
Is this 3D galaxy sand box with realistic physics simulation powerful enough to create and design different planets, gas giants and stars? The answer is a BIG yes! But are the simulation tools easy to use? The answer is even a BIGGER yes! The user interface is so friendly, that you’ll get used to it after going through the step-by-step tutorial and trying available tools for a few times. After that, you just need to use your imagination and be creative to form some unique pocket galaxies with gravity simulator based on physics rules. If you are going to redesign our lovely solar system in our galaxy, you’ll have access to all the planets (mars, moon, earth, mercury etc …) and you have the power to unlock new worlds by meeting the right conditions, colliding with the right objects, and altering mass and sea level while keeping the temperature stable. To smash stuff together and create new planets, make sure to crash the right ones together.
Tip: To raise the sea level, hit a planet with ice meteors, and use rock meteors to lower the sea level.
Orbit Sandbox Main Features at a Glance:
• Wonderful 3D graphics with smooth space simulation

This game is great! I love how realistic the stars look! I think you could add black stars (black stars are really small stars with a low mass) that would be great! Also please add more real planets and moons and asteroids and stars and dwarf planets! That would make this the most amazing mobile game ever. You could also add craters to planets after collisions and gas deformations for gas giants. Also when a large planet collides with a star in real life the star gets really bright and goes mental because of all the new material so you could add that. Thanks and carry on making your amazing game and please consider these suggestions!

Good game

This game is quite fun but could do with a few more impact textures. Could also use more detail for how to unlock the planets and other celestial bodies. Also i feel you should able to select your own colours for the planets instead of choosing from a set few and likewise with the stars. The aesthetics of the black hole could also be improved where the lensing effect could be implemented and apparition disks added when matter is pulled from certain celestial bodies. But these facts aside this is a great game and ive spent hours amusing myself!!!

Awesome but...

So the game works great I can do whatever without any glitches but here’s something that’s been going on for months now which you still haven’t fixed and that’s that when you create a universe and you place a star and a planet to orbit it, the planets shadow is normal and will move as the planet orbits the star. Well when you exit that universe and enter it again, the planets shadow is messed up and is only a fin strip of black on one side of the planet. It’s hard to explain but the planets shadow is all messed up when you enter that game again. Please fix it
