Planet Radar: Night Sky Finder
Astronomy Compass & Tracker
Free
Is that bright dot Jupiter? Point your phone at the sky and Planet Radar shows which planets are up, where to look, and whether you can see them with your own eyes.
Planet Radar shows you where the planets are in the sky, right now, from wherever you are.
What is that bright dot in the sky? Is it Jupiter? Is Mars up tonight? Can you see Saturn without a telescope? Hold up your phone and find out in seconds.
HOW IT WORKS
• Point your phone: Planet Radar works like a compass for the planets. Turn around and the planets move with you.
• In front, overhead or behind: see at a glance which planets are ahead of you, above your head or behind your back.
• Naked-eye check: the eye icon tells you whether a planet is bright enough to see without a telescope or binoculars.
• The details: azimuth, altitude and magnitude (brightness) for every planet, for stargazers who want precise numbers.
SIMPLE BY DESIGN
No star charts to learn and no clutter. Planet Radar does one thing well: it tells you where to look.
Shows the Sun, the Moon and the planets of the solar system. Never look directly at the Sun.
Great for a quick look at the night sky, backyard stargazing, or deciding where to point your telescope.
Planet Radar was previously called Planetary Compass.
Planetary Compass is now Planet Radar! Same simple way to find the planets in the sky, with a new name.
• Bug fixes and improvements
A bigger update is on the way. Stay tuned.
