Stellarium – Update for Windows

Astronomy Software


DOWNLOAD StellariumStellarium is a free open source planetarium for your computer. Visualization renders 3D photo-realistic skies in real-time with OpenGL. It shows a realistic sky in 3D. Just like what you see with the naked eye, binoculars or a telescope.

Stellarium displays stars, constellations, planets, nebulas, and other things like ground, landscape, atmosphere, etc. There is an ability to add new solar system objects from online resources.

You can add your own deep sky objects, landscapes, constellation images, scripts. The plugin system adds artificial satellites, ocular simulation, telescope configuration and more.

Stellarium is available for Linux, Unix, Windows, macOS, and Android. It is being used in planetarium projectors. Just set your coordinates and go.
