Notes about the CELX file extension:



To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened" (Windows 7) or "How do you want to open this file?" (Windows 10) if you double-click the file. There click on "More apps" and choose a suitable software to view such files on your PC or from email attachments.

The CELX file type is primarily associated with 'Celestia'. Celestia is a free real-time space simulation that lets you experience our universe in three dimensions.
