Planet Wheel

The Planet Wheel is a compact and convenient tool to help you track the planets of the Solar System through the sky. The main 'wheel' display shows you the positions of the Sun, Moon and all the major planets at a glance, and the app also includes a starmap to show you how to find the planets against the background of stars.

The Planet Wheel app is an interactive version of the popular service on the Electronic Sky Website, with a host of extra features to help you find your way around the Solar System.

Use the Planet Wheel to:

- Quickly identify a planet in the sky
- Check the location and visibility of the planets, or the Moon
- Locate Solar System objects on a starmap
- Look back or forward in time up in a range of two hundred years
- See which constellations are most visible
- Check the Moon's phase
