Could you build this?
Partial The web/mobile shell and social commenting are straightforward, but accurately rendering an interactive 3D celestial sphere of nearly 1 million stars mapped to real coordinates requires specialized graphics and spatial indexing skills.
What it would actually take: The technical core requires WebGL/Three.js or native Metal/Vulkan shaders paired with astronomical catalogs (e.g., Hipparcos/Gaia datasets). The hard engineering problem is rendering up to 1,000,000 stellar point primitives at 60+ FPS on mobile hardware using spatial octrees or KD-trees for raycasting/selection, alongside coordinate transformation math (right ascension/declination to real-time local horizon coordinates).
