Stellarium Description

Stellarium is a comprehensive utility that helps users explore planets and constellations in a 3D environment. This open-source planetarium gives you details about celestial objects, simulates solar and lunar eclipses, and displays Messier objects and the Milky Way.

Interactive 3D environment for celestial exploration

As soon as you run the application, it opens in full screen mode. With just one click on the sky, you can get details about the aimed object, namely type (e.g. star, double star, cluster associated with nebulosity), magnitude, galactic longitude and latitude, parallax, distance, spectral type, and angle.

Fill out information to examine specific objects

The objects can be viewed with the use of a telescope, which can be configured in terms of name, focal length and diameter. Plus, you can pick a location on the map and select the latitude, longitude, altitude and country to jump to it.

Examine past constellations easily

An interesting feature offered by this program is the possibility to travel back in time and see the constellations’ positions and other details on the sky. You only need to set the date and time in the dedicated dialogs, and Stellarium automatically generates projections from that period.

Show or hide specific objects

Furthermore, you can adjust the Milky Way brightness and make the program show the atmosphere, shooting stars and planet orbits, as well as view information about the celestial sphere (e.g. equatorial grid, cardinal points, Azimuthal grid).

Stellarium allows users to select the projection mode (fish-eye, cylinder, Mercator), view landscapes from different world locations and add new ones from ZIP archives, and learn about different sky cultures.

Resort to handy tools

You can perform searches for finding objects on the sky, navigate throughout the 3D environment with the use of keyboard shortcuts (which can be reassigned) or the mouse, toggle between daytime and nighttime, enable the ocular viewing mode, and view deep-sky objects.


All in all, Stellarium offers excellent image quality and a pack of features that make it an ideal tool for all types of users curious enough to find out more information about constellations and other celestial objects.
