軌道を回る惑星とフォーカスカメラ付きのインタラクティブ3D太陽系

Build an interactive 3D solar system explorer that runs in the browser. Show a bright glowing sun at the centre of a dark starfield, with the planets orbiting it on visible orbit lines at different speeds. Each planet should have a detailed textured surface, and the camera should be able to fly in close to the sun or to any planet, such as the reddish Mars, and zoom back out to the full system view. Add a side panel listing the bodies, so selecting one focuses the camera on it and shows basic facts, plus controls to pause or speed up time. Keep the interface dark and minimal, with clean light typography. Use WebGL, preferably Three.js, and deliver everything as a self-contained web page. Done means the whole system animates smoothly, planets can be selected from the list, the camera transitions are fluid, and the sun glow and planet textures look convincing in close-up.
