I need to create a single-page web app with a 3D solar system using three.min.js. The requirements are:

1. Single self-contained file named index.html
2. CSS in <style> tags, JS in <script> tags
3. No external resources or network requests
4. Use the pre-provided three.min.js file
5. Features needed:
   - Sun and orbiting planets
   - Varied speeds and sizes
   - Orbit-drag camera controls
   - Starfield background

Let me first check if three.min.js exists in the current directory, then create the index.html file.

Let me use bash to check the directory contents.

Great! The three.min.js file is present. Now I'll create the complete single-page web app with the 3D solar system. I'll include:

1. HTML structure with a canvas container
2. CSS for styling
3. JavaScript that:
   - Sets up the Three.js scene, camera, and renderer
   - Creates the sun and planets with different sizes and speeds
   - Adds orbit controls for camera interaction
   - Creates a starfield background
   - Animates the planets orbiting the sun

Let me write the complete index.html file.

Perfect! I've created a complete 3D solar system web app in a single index.html file. The app includes:

1. **HTML Structure**: Clean HTML5 structure with a container for the 3D scene and an info panel
2. **CSS**: Styling for a black background and info panel with semi-transparent background
3. **JavaScript Features**:
   - Three.js scene setup with camera and renderer
   - Starfield background with 10,000 stars
   - Sun with emissive material and point light
   - 8 planets (Mercury through Neptune) with realistic relative sizes and orbital distances
   - Each planet has different orbital speeds and colors
   - Orbital paths visible as subtle lines
   - Saturn includes rings
   - Custom orbit-drag camera controls (drag to rotate, scroll to zoom)
   - Smooth animation with planet rotation and orbital motion
   - Responsive design that handles window resizing

The app is completely self-contained with no external dependencies except for the provided three.min.js file. It runs fully sandboxed with no network requests.
