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

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

You can add your own deep sky objects, landscapes, constellation images, scripts. The plugin system provides 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.

Stellarium Features:


  • default catalog of over 600,000 stars
  • further catalogs with more than 177 million stars
  • default catalog of over 80,000 deep-sky objects
