Could you build this?
Partial Building a standard 3D solar system in Three.js is achievable, but rendering and propagating orbits for 526,000 asteroids and thousands of satellites in real-time requires high-performance graphics optimizations.
What it would actually take: Stack requires WebGL/WebGPU (via Three.js or custom shaders) and Web Workers. The difficult challenge is propagating orbital mechanics (Keplerian elements, SGP4 for satellites) for 500k+ bodies at 60 FPS, necessitating GPU compute shaders or InstancedMesh optimizations with heavily optimized spatial indexing, binary packed orbital datasets, and level-of-detail management.
