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
The user wants me to build a 3D solar system web app using Three.js. Let me first check what's in the current directory and understand the three.min.js file available.
I'll inspect the workspace and Three.js build so I can make a self-contained solar system page.

Let me check the THREE.js version and available APIs from the minified file.

thinking
It's Three.js r128 or similar from 2021. I need to check if OrbitControls is included or if I need to implement my own orbit-drag camera. The user said to load three.min.js only, no other files.
{"command":"grep -oE 'REVISION:\"[0-9]+\"' three.min.js | head -1; grep -c 'OrbitControls' three.min.js; grep -oE 'exports\\.[A-Z][A-Za-z0-90
thinking
Let me check the THREE version and what's available. The file starts with a UMD wrapper. Let me look at more of the beginning to understand the API.
{"path":"/tmp/ws/three.min.js","offset":1,"limit":5}/** * @license * Copyright 2010-2021 Three.js Authors * SPDX-License-Identifier: MIT */ [2 more lines in file. Use offset=6 to continue.]
thinking
This is Three.js r128 or similar from 2010-2021. I need to check if it's UMD and how THREE is exported. Let me look at the end of the file.
{"path":"/tmp/ws/three.min.js","offset":6,"limit":3}[Line 6 is 589.2KB, exceeds 50.0KB limit. Use bash: sed -n '6p' /tmp/ws/three.min.js | head -c 51200]
thinking
This is Three.js r128 or similar from 2020-2021. I need to implement orbit-drag camera controls myself since OrbitControls is not included. I'll write a complete single-page solar system.
Building a self-contained solar system with custom orbit-drag controls, procedural planet textures, and a starfield.

The file is written. Let me verify THREE API compatibility with the 2010-2021 build. This is likely r128 or similar (copyright through 2021).
Checking that the Three.js build exposes the APIs I used:
{"command":"python3 - <<'PY'\nimport re\ns=open('three.min.js').read()\n# revision\nm=re.search(r'REVISION:\"?(\\d+)\"?', s)\nprint('REVISIO/bin/bash: line 1: python3: command not found Command exited with code 127
thinking
python3 not available, try node instead

Good - THREE r128 is available as a UMD global. All the APIs I used exist. The page is self-contained with three.min.js loaded via script src.
`index.html` is a self-contained 3D solar system that loads the local `three.min.js` (r128). - **Sun** with a procedural surface, corona, and additive glow sprite, plus a point light. - **8 planets** at different distances, sizes, orbital speeds, axial tilts, and spin rates (Earth has a moon; Saturn has rings). - **Orbit-drag camera**: left-drag orbit, scroll zoom, right/middle-drag pan, plus reset. - **Starfield** (~4500 stars) and faint dust. - **HUD**: time scale, pause, orbit-line toggle. Open `index.html` in a browser to run it — no network required.

EVALUATION
3D solar system with sun, orbiting planets of varied sizes/speeds, orbit rings, starfield, and camera zoom/drag response.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
