I'll build a 3D solar system with the sun, orbiting planets, drag-based camera controls, and a starfield background. Let me first check what's available in the current directory.

Great, three.min.js is present. Now I'll create the complete solar system web app.

The 3D solar system is complete! Here's what I've built: ## Features - **Sun** - Central star with pulsing glow effect and dynamic lighting - **8 Planets** - Mercury through Neptune, each with: - Unique sizes and orbital distances - Different orbital speeds (closer planets orbit faster) - Distinct colors and surface characteristics - Saturn has animated rings - **Orbit-drag Camera Controls**: - **Left drag** - Rotate around the solar system - **Right drag** - Pan the view - **Scroll wheel** - Zoom in/out - **Touch support** - One-finger drag, two-finger pinch zoom - **Starfield** - 5000 procedurally generated stars with varied colors - **Interactive Planet Labels** - Hover over a planet to see its name and details - **Orbit paths** - Visual rings showing each planet's orbital track The camera smoothly interpolates all movements, and planets rotate on their axes while orbiting at realistic relative speeds. The sun pulses gently and casts dynamic light across the system.
