Celestia is a rare Linux app <i>not</i> on Flathub, but it is available from Fedora's Flatpak repo, which <i>in theory</i> should be usable on any distro: <a href="https://github.com/CelestiaProject/Celestia/discussions/1988">https://github.com/CelestiaProject/Celestia/discussions/1988</a>
You can enhance the base version with extras from <a href="https://celestiaproject.space/addons.html" rel="nofollow">https://celestiaproject.space/addons.html</a>.<p>There are high-resolution textures for Solar system objects, and even mythical stuff from Star Trek.
I have a hobby project to move Celestia to Web and uses its data files<p><a href="https://celestiary.github.io/" rel="nofollow">https://celestiary.github.io/</a>
