Cosmonium is a 3D astronomy and space exploration program. With Cosmonium you can navigate in our solar system and discover all the planets and their moons. You can also visit the neighboring stars and discover the true size of our galaxy and the Universe.
Cosmonium also supports (or will support) the creation of fictional planets and stellar system using procedural generation.
Cosmonium also already supports some Celestia addons (though CMOD and CelX are not yet supported).
Cosmonium runs on Windows, Linux or MacOS machine with a graphic card supporting OpenGL 2.1 or better (OpenGL 4.5 is recommended), 2GB of memory and at least 512MB of disk (up to 4GB if the HD and UHD textures are installed).
Download the package for your platform from the Download page and extract the package archive file, or look at the Installation page to install from sources.
The package contains only low resolution textures, see the Installation page to install extra HD and UHD textures.
