Stellarium is a free Planetarium (Astronomy) Software ➤ Download Now!

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.

This software 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 deep sky objects, landscapes, constellation images, and scripts. The plugin system adds artificial satellites, ocular simulation, telescope configuration, and more.

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