The Grand Orrery

A Solar System Field Guide

$2.99

The whole solar system, drawn like an antique atlas and checked against NASA. $2.99 once — no subscriptions, no ads, nothing collected. No subscriptions. No ads. No accounts. The whole solar system. 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 - Works completely offline; collects nothing Buy it once. Keep the solar system in your pocket.

The Grand Orrery is now built for iPad and Mac. On iPad, the whole solar system fills the screen in both portrait and landscape, with type and controls scaled for the larger canvas — and the worlds now render at higher resolution, so close-ups of Mercury, the Moon and the outer moons stay crisp. On Mac, the app runs in its own resizable window with full-screen support, a proper menu bar, and keyboard shortcuts — press Space to pause, the arrow keys to change speed, and O, L or T to toggle orbits, labels or the Grand Tour. Scroll to zoom in and out. One purchase covers iPhone, iPad and Mac.
