Fly the solar system on real JPL orbits, in your browser

2 followers

SOLAR — an interactive 3D solar system you fly through in the browser. Real JPL orbital elements (1800–2050), Kepler's equation solved live, cinematic time-warp travel between planets, a top-down ecliptic map, in-flight music. A non-commercial pet project built with React + Three.js, largely vibe-coded with Claude Code. Mobile-first — works as well on a phone as a desktop.

We didn't use Vercel for this one — SOLAR is self-hosted (Docker + Caddy on our own server), mainly because of the Node presence/feedback service and Postgres-backed accounts running alongside the static frontend. That said, we'd genuinely love to move onto Vercel — the frontend itself (React + Three.js) is a natural fit, we're just weighing how to carry over the backend pieces (feedback API, accounts) without losing them.

SOLAR is a browser-based 3D solar system, built as a non-commercial side project. Planet positions come from JPL's orbital elements (1800–2050), with Kepler's equation solved on the client in real time — not pre-baked animation. You can fly between planets with a cinematic time-warp, plus a top-down ecliptic map with both compressed and true distance scales. Stack: React + Three.js, TypeScript, tested against JPL reference positions. Built mobile-first. Largely vibe-coded with Claude Code — a personal project, not a product. Caveats: UTC used as TDB approximation, no N-body integration, no moons modeled. Happy to answer questions about the orbital math or the rendering.
