Find constellations in tonight's real sky and trace their stars. Star map game!
Star Finder is a constellation game played on the real night sky above you, right now.
Like a star map or planisphere, it shows tonight's sky, and you learn the shapes and names of the constellations as you play.
★ A constellation app on the real sky
- Uses your location and the current time to show the stars you can see tonight
- About 5,000 real stars, plus the Sun, the Moon (with its phases), Mercury, Venus, Mars, Jupiter and Saturn in their true positions
- The game starts with the part of the sky your phone is facing, so you can compare it with the real night sky - great practice for stargazing
- A compass at the top right shows which direction you are looking
★ How to play
- You are asked to find a constellation, such as Orion
- When you spot it, trace its stars with your finger to join them with lines
- Trace all of its stars to get it right, and the constellation figure appears
- Move two fingers to look around the sky, and pinch to zoom
- Stuck? 💡Hint moves the sky to the constellation for you
★ Learn the constellations
- 15 constellations: Orion, Taurus, Gemini, Canis Major (Sirius), Leo, Ursa Major (the Big Dipper), Ursa Minor (Polaris, the North Star), Crux (the Southern Cross), Lyra (Vega), Aquila (Altair), Cygnus (Deneb), Scorpius, Sagittarius, Pegasus and Cassiopeia
