LumaOrbit: Sun, Moon & Shadows

Follow daylight around Earth, trace the Sun and Moon, and explore locally visible eclipses across a century.

See the sky’s rhythm on the map.

LumaOrbit turns any place and time into a clear, interactive view of daylight, moonlight, shadows, twilight, and eclipses. Move across the map, travel through time, and watch the geometry of the Sun and Moon change instantly.
