Identify your
night sky.

Upload a smartphone photo of the stars — rotating.earth identifies exactly what you're looking at and returns celestial coordinates, constellation overlays, and planet positions.

How it works

Three steps to identify your sky

1
Take a photo

Point your smartphone at the night sky and shoot. GPS and timestamp are read automatically from EXIF data — or you set them manually on a map.

2
We plate-solve it

Your image is matched against a star catalogue across a distributed worker cluster. Most images are identified in under 30 seconds.

3
Explore the result

Get exact celestial coordinates, an azimuthal grid, horizon line, bright star labels, constellation lines, and real-time planet positions overlaid on your photo.
