Stellarium 25.1 / 1.2 – Free Planetarium

Stellarium 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.

The app displays stars, constellations, planets, nebulas and others 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 artifical 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.
