The celestial bodies are Three.JS meshes.

I used loaders (namely 'useLoader' from R3F and 'GLTFLoader' from 3JS) to import 3D models, such as International Space Station. More on loading models in R3F: https://docs.pmnd.rs/react-three-fiber/tutorials/loading-mod...

I've future plans for this side project. It would be great to hear from the HN community before diving into them. Enjoy!

P.S: Getting an empty (probably black) screen? This app shows up in browsers that support WebGL2.0 (most modern browsers do). Check this site to see whether your browser supports WebGL2.0: https://get.webgl.org/webgl2/

P.S.S: There'll probably be responsive design issues. I'd highly encourage you to use a desktop version or rotate to landscape while using a mobile version.
