Stellarium is a free and open-source planetarium, licensed under the terms of the GNU General Public License version 2 or any later version, available for Linux, Windows, and macOS. A port of Stellarium called Stellarium Mobile is available for Android and iOS. These have a limited functionality, lacking some features of the desktop version. All versions use OpenGL to render a realistic projection of the night sky in real time.

Stellarium was featured on SourceForge in May 2006 as Project of the Month.
