De film is een adaptatie en uitbreiding van de Planetarische visuele roman van Key. Het verhaal speelt zich af in een dystopische toekomst waarin biologische en nucleaire oorlogsvoering een ooit welvarende beschaving volledig in puin heeft achtergelaten. De film vertelt het verhaal van een oude man die rondreist met een mobiele planetarium projector om mensen de sterren te laten zien.
Nee, helaas is planetarian ～星の人～ nog niet beschikbaar op Netflix in Nederland.
