I don't know why World Wide Telescope doesn't get more love: https://worldwidetelescope.org/download/

Celestia is a rare Linux app not on Flathub, but it is available from Fedora's Flatpak repo, which in theory should be usable on any distro: https://github.com/CelestiaProject/Celestia/discussions/1988

You can enhance the base version with extras from https://celestiaproject.space/addons.html.

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

Celestia is good but if you're willing to leave the free software space you might enjoy "Space Engine" more.

Nice, but Windows only.

I'm using it as a 'screen saver' for my second monitor when i don't need it.

Does this run on VR/Oculus?

Stellarium recently released an alpha on Oculus
