**Building Solar System Scene**

I'm currently integrating the core elements for our 3D solar system visualization. My focus is on establishing the scene, incorporating `three.min.js`, and laying the groundwork for the Sun, planets with their unique orbits and scales, starfield, and camera controls.

**Adding Celestial Bodies**

I'm now focusing on bringing the celestial bodies to life. My current work involves creating the geometries and materials for the Sun and initial planets, positioning them, and beginning to define their orbital paths and individual rotations.

**Structuring HTML File**

I am now focusing on the foundational HTML structure for our solar system. My current work involves setting up the `index.html` with necessary script inclusions and defining the canvas element, preparing for the integration of Three.js functionalities.

**Building HTML Structure**

I'm currently focused on constructing the `index.html` file. After confirming `three.min.js` is accessible, my next step is to define the HTML structure and then integrate the Three.js specific code within it.

**Drafting HTML and Code**

I've drafted the basic `index.html` structure and confirmed `three.min.js` is available. My immediate focus is now on initiating the JavaScript code, starting with core Three.js setup elements and then defining the planet data.

**Building Solar System Scene**

I've initiated the `index.html` by establishing the core Three.js setup. This includes the scene, camera, renderer, and OrbitControls for navigation. I've also incorporated ambient and point lights and begun the solar system with the sun, using a basic yellow material.

**Refining Solar System Elements**

I've moved beyond the basic sun and am now implementing multiple planets, each with unique sizes, orbital distances, and speeds. I'm also handling self-rotation separately from orbital motion. Additionally, a starfield background using `THREE.Points` has been added, and the animation loop is functional with a resize handler.
