Clockwork Sky — Real-Time Solar System New Tab

Clockwork Sky turns every new tab into a live solar system. Planet positions are computed from real Keplerian orbital elements — the same mathematics planetarium software uses — and update continuously. Nothing is fetched from an API. The orrery runs entirely in your browser, offline. FIVE ART STYLES Switch between Cinematic, Clay, Paper Cut, Retro Poster, and Watercolor. Each is a distinct rendering technique with real planet textures, not a recolour. WIDGETS (turn any on or off) - Moon phase and illumination - Next full moon / new moon - Mercury retrograde alert (geocentric — the real phenomenon) - Earth-to-planet distances and light-speed delay - Solstice and equinox countdown - Sunrise and sunset - Day/night globe - World clock, focus timer, quick notes, habit tracker, and more PRIVACY No servers. No accounts. No analytics. No network requests. Everything stays in your browser.
