之前分别用阿里通义千问 Qwen2.5-Max 、Grok 3，以及 Claude 3.7 Sonnet 生成了 3D 地月系统模拟的代码。通义千问和 Grok 3 都一次性生成了准确完整的代码，Qwen 生成的较为美观，Grok 速度更快，操作性更强。Claude 第一次生成有错误，经过两轮修改后修复了错误，代码质量比前两者要高。
从开始生成代码到完成，DeepSeek 新版 V3 仅用了 1 分钟，且一次性生成，没有任何错误。生成的代码不仅准确地模拟了地月系统的运动方式，还展现了极高的细节品质。地球和月球的纹理非常精美，尤其是地球的纹理，完整呈现了地形地貌的细节，视觉效果十分逼真。此外，系统的缩放和旋转操作也非常流畅，用户体验极佳。
提示
请基于 Three.js 制作地月系统演示，Three.js 使用 cdn，输出一个完整的html文件
