Extra catalogues with more than 210 million stars. Default catalogue of over 600,000 stars. Some amateur astronomy groups use it to create sky maps for describing regions of the sky in articles for newsletters and magazines. Because of the high quality of the graphics that Stellarium produces, it is used in some real planetarium projector products. Stellarium may be used as an educational tool for teaching about the night sky, as an observational aid for amateur astronomers wishing to plan a night's observing, or simply as a curiosity (it's fun!). It can also draw the constellations and simulate astronomical phenomena such as meteor showers, and solar or lunar eclipses.

Stellarium calculates the positions of the Sun and Moon, planets and stars, and draws how the sky would look to an observer depending on their location and the time. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.
