About the Orrery
The sky is bigger than your screen.
The Orrery opened in 1966 with a single projector, a handful of chairs and an astronomer who loved the Moon.
Since 1966
A hill, a dome and a very dark sky.
We sit above the Sonoran desert, where the nearest city light is forty miles away. Our 220-seat dome shows the whole sky at 8K, our observatory lets you look through a 36-inch telescope, and our science hall lets children feel what gravity does to a marble.
- A 220-seat 8K full-dome theatre
- A working 36-inch research telescope
- A hands-on science hall for all ages
What we do
Three things we care about.
Real astronomy
Every show is checked by a working astronomer and updated when the science changes.
For everyone
Relaxed shows, captioned shows, tactile models and tickets from $5.
Dark skies
We work with the county to keep the valley dark for stargazing.
