Watch and explore outer space with Stellarium, Celestia, and Xplanet

Ubuntu founder Mark Shuttleworth spent about $20 million to go into space, and he never got farther away from Earth than a few hundred miles. Using three free software programs, you can look at and virtually travel to places millions of miles away without leaving your GNU/Linux desktop or paying a dime.

NAME
stellarium - A real-time realistic planetarium SYNOPSIS
stellarium [OPTIONS] DESCRIPTION
Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and MacOSX. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope. OPTIONS
-v, --version Print program name and version and exit. -h, --help Print a brief synopsis of program options and exit. --safe-mode Do not use OpenGL2 features (such as shaders). Useful on systems that report support for OpenGL 2, but its implementation is buggy. Used as a work-around for the "broken fonts" bug. -c, --config-file file Use file for the config filename instead of the default config.ini. -u, --user-dir dir Use dir instead of the default user data directory ($HOME/.stellarium/ on *nix operating systems). -f, --full-screen yes|no With argument yes or no over-rides the full screen setting in the config file. The setting is saved in the config-file and as such will be the default for subsequent invocations of Stellarium. --screenshot-dir dir Set the directory into which screenshots will be saved to dir, instead of the default (which is $HOME on *nix operating systems). --home-planet planet-name Specify observer planet. planet-name is an English name, and should refer to an object defined in the ssystem.ini file. --altitude alt Specify the initial observer altitude, where alt is the altitude in meters. --longitude lon Specify the initial observer longitude, where lon is the longitude. The format is illustrated by this example: +4d16'12" which refers to 4 degrees, 16 minutes and 12 arc seconds East. Westerly longitudes should be prefixed with "-". --latitude lat Specify the initial observer latitude, where lat is the latitude. The format is illustrated by this example: +53d58'16.65" which refers to 53 degrees, 58 minutes and 16.65 arc seconds North. Southerly latitudes should be prefixed with "-". --list-landscapes Print a list of landscape names and exit. --landscape name Start Stellarium using landscape name. Refer to --list-landscapes for possible names. --sky-date date Specify sky date in format yyyymmdd. --sky-time time Specify sky time in format hh:mm:ss. --fov fov Specify the field of view (fov degrees). --projection-type p Specify projection type, p. Permitted values of p are: equalarea, stereographic, fisheye, cylinder, mercator, perspective, and orthographic. RETURN VALUE
0 Completed successfully. not 0 Some sort of error. FILES
Note: file locations on non-*nix operating systems (include OSX) may vary. Please refer to the Stellarium User Guide for more details, as well as information on how to customise the Stellarium data files. /usr/share/stellarium/ This is the Installation Data Directory set at compile-time. $HOME/.stellarium/ This is the User Data Directory, which may be over-ridden using command line option -u. It contains the user's settings, extra landscapes, scripts, and can also be used to over-ride data files which are provided with the default install. $HOME/.stellarium/config.ini The default main configuration file is config.ini. Refer to -c above to use a different filename and to -u to use a different User Data Directory. $HOME/ The default screenshot directory. Refer to --screenshot-dir to use a different path. SEE ALSO
