  • Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets and nebulae, and has many other features including multiple panoramic landscapes, fog, light pollution simulation and a built-in scripting engine.
  • Stellarium comes with a star catalogue of about 600 thousand stars and it is possible to download extra catalogues with up to 210 million stars.
  • Stellarium has multiple sky cultures - see the constellations from the traditions of Polynesian, Inuit, Navajo, Korean, Lakota, Egyptian and Chinese astronomers, as well as the traditional Western constellations.
  • It is also possible to visit other planets in the solar system - see what the sky looked like to the Apollo astronauts, or what the rings of Saturn looks like from Titan.
