Our take on Solar System Simulator

Rather than organizing space exploration around missions or a fixed progression, this sandbox centers on modifying celestial bodies and observing the resulting orbital changes. Its focus is constructing and exploring systems, not pursuing a campaign objective.

What is Solar System Simulator?

Explore planets and moons across the solar system, or visit nearby stars and view their positions in the Milky Way.

The game also lets players alter existing celestial bodies or add new ones to create custom solar systems. In this sandbox, gravity and physics determine how the bodies move, with orbits recalculated according to Newton's laws. This desktop edition of the mobile game has higher-quality texture and height maps, along with smoother gameplay. The vendor says additional features are planned.

How Solar System Simulator plays

01Custom solar systems
Change existing bodies or add new ones, with their orbits recalculated through the gravity simulation.
02Nearby star exploration
Visit stars near the solar system and see where they are located in the Milky Way.
03Desktop maps
The desktop edition uses higher-quality texture and height maps than the mobile game.
