Stellarium is a virtual planetarium that allows users to look up into the sky from different locations on the planet and view a 3D representation of over 120,000 stars, planets of solar system with their satellites, solar and lunar eclipses, constellations of the Zodiac and many more.
You can explore the space and learn more about planets and constellations, zooming in and out into the sky, selecting different objects and finding out more details about them.
The application features several visual effects, allowing you to turn on and off constellation lines and labels, atmosphere, satellite hints and cardinal points, planet labels and orbits, display Equatorial/Azimuthal grid or switch to night mode.
Furthermore, you can travel forward and backward in time with different time speeds, change the default location on Earth as well as the date and time, search for certain objects across the sky and view them through a telescope.
Stellarium uses different world map projection methods such as Perspective, Stereographic, Fish-eye, Cylinder, Mercator and others and also integrated different sky cultures and landscape graphics you can choose from.
