The Grand Orrery is a hand-built model of our solar system, drawn in the
style of an antique astronomical atlas and powered by a native Metal
renderer. Twenty-five worlds — the Sun, every planet, Pluto, and fifteen
notable moons — spin and orbit in real time. Tap any of them and the
camera sweeps you to its sunlit side while its field-guide dossier slides
up: measurements, atmosphere, notable moons, and the kind of margin notes
an astronomer would actually tell you at the eyepiece.
Every world's surface is generated on your phone — except Earth,
which wears NASA's own Blue Marble portrait — and every figure in every dossier was verified against NASA and
JPL references, with the sources one tap away.
- Pinch, drag, and fly through a living orrery rendered at up to 120 fps
- Field-guide dossiers for 25 worlds, checked against NASA and JPL
- The Grand Tour: sit back while the orrery visits each world in turn
- A quiet, generated ambient soundscape (leave it on or switch it off)
- Orbit lines, floating labels, adjustable time — from hours to years
per second — and a pause button when you just want to look
- Sources for every world, cited in the app
