Running Gaia Sky

If you installed the software using an installer or a package manager system (rpm, deb), you just need to use the standard running procedures of your Operating System to run the application.


In windows, this means clicking on Start and then browsing the start menu folder Gaia Sky. You can run the executable from there.


Just type gaiasky in a terminal or use your favourite desktop environment search engine to run the Gaia Sky launcher.


Locate the launcher using the main search.

Code and pakcage

However, if you are a maverick and do not like installers, you can also run the Gaia Sky directly from the source code in GitHub or using the tgz package.

Running from source


If you want to compile the source code, you will need the following:

Please, be aware that only tags are guaranteed to work (here). The master branch holds the development version and the configuration files are possibly messed up and not ready to work out-of-the-box. So remember to use a tag version if you want to run it right away from source.

Also, this guide is for Unix-like systems only. If you are working on Windows, you will need git for windows and Power Shell, even though it has not been tested.

First, clone the repository:

$ git clone
$ cd gaiasky

Compile and run

The TGAS catalog files (Gaia data) are not in the repository, so if you want to use TGAS when running from source you either need to choose HYG in the Data tab of the configuration dialog or download the tar file corresponding to your version:

You must extract the contents tarball into the folder gaiasky/android/assets/data/octree. In the case of the multifile package, you need to keep the directory structure.

Please make sure to get the TGAS data files if you want to use them before running from source. To compile the code and run the desktop version of the application:

$ gradlew desktop:run

Package Gaia Sky

To pack the application into a tar.gz file:

$ gradlew desktop:createTar

In order to produce the desktop installers for the various systems you need a licensed version of Install4j.

$ gradlew desktop:pack

These commands will compile and package the application into a gaiasky-[version] folder under the gaiasky/releases folder.

Running from downloaded package

If you prefer to run the application from the tar.gz package, follow the instructions below.


In order to run the application on Linux, open the terminal, uncompress the archive, give execution permissions to the file and then run it.

$ tar zxvf gaiasky-[version].tar.gz
$ cd gaiasky-[version]/
$ gaiasky


In order to run the application on Windows, open a terminal window (type cmd in the start menu search box) and run the run.bat file.

cd path_to_gaiasky_folder


To run the application on MacOS systems, follow the instructions in the Linux section.
