About Space Sandbox
Build your own cosmic system in 3D space with Space Sandbox! Manipulate gravity, time, and orbits to create planets, stars, and black holes.
How to play
Select an item from the left panel: a planet, star, moon, gas giant, or black hole, and place it in the scene by clicking on the space canvas. To choose an object, simply click on it. After that, you can adjust the camera focus, track its movement, accelerate it, stabilize its orbit, or remove it. Modify the time speed to observe the accelerated motion of planets and the evolution of the system. Tweak gravity settings to create a serene, realistic, or turbulent simulation. Zoom in and out using the mouse wheel or a pinch gesture. Hold Shift, use the right mouse button, or drag with two fingers to navigate the camera. Double-click to center on an object. Your progress is saved automatically. Design, experiment, and construct the most stunning or bizarre space system!
