Funny I should see this on the front page of HN the day before I finish my Stellarium port for Nintendo Switch [1]. Unfortunately a lot of the UI code in the 1.0 release made it harder to port so I'm currently basing the Switch version on the 0.xy tags, but it's still a great accomplishment for the Stellarium team!
1: Unless I get approval from Nintendo AND Noctua you will need an RCMed Switch with Atmosphere to run it.
