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

I really like this game! But if you can just make a little update like if you can put inclination which the orbit of a planet goes up and down and also put farther camera zoom out and when you put a black hole very far away, it doesn’t affect any objects, and lastly, if you could make a button on the settings of a star called the end life button which will make the star end its life, if it is a yellow star, it turns into a white dwarf, if it’s a red giant, it turns into a white dwarf, if it’s a blue giant, it turns into a neutron star or black hole. And add more objects like brown dwarfs (which are failed star or burned up gas giants) red dwarfs (which is a small red star) a protostar (which is not a star or brown dwarf it is a small object with stuff coming out of the top) supergiants (which are huge stars larger then the blue giant) and neutron stars (which are stars WAY smaller than an asteroid and has very strong gravity). And add a button when you place an object and go to its settings were you can change the mass of any objects. And also in the settings of a object can you add how a planet spins.

THIS GAME IS AWESOME!!! It is very entertaining to play, I love doing both build a habitable solar system, and just destroying stars with a black hole. Sometimes both lol. Plus, it is super super battery efficient. But what would make the game 1000 times better is if you could make official gas rings around black holes, that way I could make a habitable solar system with a black hole. Another thing about black holes, is when a star gets destroyed by one, it just explodes, I would suggest that the star gets speggettified first, and creates a disc around the black hole like reality. Also, another thing, I feel like life evolves on planets really fast. Like you definitely want to speed it up from reality so the game isn’t boring, but I think it needs to be slower than it is. Another suggestion is make the fabric of space actually bend to provide a visual effect of gravity in real life. Last thing, consider putting “Time Shift” (Einstein’s theory of Realitivity)

Good game, but could use some fixes

Ok so here’s some info that the other reviews don’t usually have (because they are at least a year old most of them!) so let’s start with planet orbits. It can be frustrating but if you put drag your finger to what you want it to orbit it will go in a perfect circle (or near it if there are other stuff) unless your orbiting a planet in which there’s a chance of it failing. Everything but asteroids counts as a “planet” including black holes and if you tap something and then tap what pops up when you do you can find how to change what it is doing and also destroy it. My game also freezes at times in some areas so I can mostly just watch sadly and can you increase the starting max amount of planets to 5 and make so you only watch ads for extra planets otherwise it will stay at 3 stars. Also you should have lines between where your planets can support life and planets should be able to get life again as well for less confusion and add a tutorial. Otherwise it is a good game and there’s some things you should add like life on planets being able to explore space and fight other space explorers or make peace with them and so on.
