Lighter in what way?oops wrote: ↑Sat Jul 28, 2018 5:08 pmGreat, Stellarium is very powerful
... But I can not find into MX repository a lighter astro. app. (like sky map for android, or Celestia)
Celestia (26MB only)
.. Or is an alternative exists into MX ?
Kstars is smaller than Stellarium, but it would pull in KDE runtime libraries if you don't have them.
Google Earth has some planetarium features, too.
If you want the successor to Celestia, Space Engine for Windows will run in Wine if your system meets the requirements, such as a discrete video card with at least 2 GB--that's a lot heavier than Stellarium, too.
