Using the pre-provided three.min.js (global THREE), build a 3D solar system with the sun and orbiting planets at varied speeds and sizes, orbit-drag camera controls, and a starfield.
thinking
We need to create index.html containing everything: load three.min.js via <script src="three.min.js"></script>. Build a 3D solar system with sun and planets, orbital motion, camera controls (orbit drag). Since THREE is available, we can use OrbitControls which is part of examples, but not sure if included. The only library present is three.min.js; OrbitControls may not be present. But we can implement simple controls by listening to mouse drag to rotate camera around target. Simplify: implement basic orbit controls manually: track mouse move, change spherical coordinates theta, phi, radius. Create scene, camera (PerspectiveCamera), renderer, add starfield: many points in sphere. Add Sun: sphere mesh with emissive material. Add planets: array with parameters: distance from sun, size, orbital speed, color. In animation loop update each planet's position based on time. Add simple ambient light and point light at sun. Add resize handling. Write to index.html. We need to ensure script runs without external dependencies. Let's write index.html accordingly.
