About SpaceSim

SpaceSim is a free, browser-based universe simulator designed for space exploration and education. Created by Romain Simon, the platform allows users to instantly journey through the cosmos without the need for any signup or account creation.

With SpaceSim, users can travel through a real-time, UTC-driven 3D Solar System and inspect source-linked scientific state data. The simulator also features the ability to observe Earth from a pinned NASA ISS trajectory, build procedural stars, visit compact objects, and collect virtual postcards of your discoveries.

To ensure transparency and educational accuracy, SpaceSim clearly labels all of its content as scientific, reconstructed, representative, procedural, experimental, or promotional.
