Stellar Tour - AR Stargazer
iOS Universel / Education
Stellar Tour is the only AR stargazing app written by an astrophysicist. Point your phone at the night sky and get a guided tour of everything up there: two billion real stars, every planet and major moon, eclipses, meteor showers, and 13,000 deep-sky objects.
Astrophysicist Dr. Aaron Day wrote every word. Instead of the standard flood of random facts, Stellar Tour tells the scientifically accurate story of each world: what it is like on the ground, in the seas, or floating through the clouds.
THE NIGHT SKY, FOR REAL
• Two billion stars from ESA's Gaia survey, each in its true position. Pinch to zoom from your backyard to the galactic core.
• The Milky Way as it actually looks, with constellations, planets, and satellites overlaid on your live sky.
• Night Vision mode keeps your eyes dark-adapted with a pure red display.
ECLIPSE EXPLORER
Simulate any solar or lunar eclipse from your exact location: local timings, a disc animation of the Moon crossing the Sun, and a live countdown. Built for the total eclipse of August 12, 2026.
PLAN YOUR NIGHT
• Sky Calendar: every eclipse, meteor shower, conjunction, and full moon. The week ahead is free; the full year comes with the expansion.
• Night Planner: the best targets for your sky tonight, hour by hour. Cloud cover from the weather forecast is reported so you can plan ahead.
• Reminders that fire only when something is worth stepping outside for, including the International Space Station and Tiangong Space Station passes with a live countdown.
GO DEEPER
• Telescope Catalog: 13,000 NGC, IC, and Messier objects, searchable and shown on your sky.
• Exoplanets: nearly every known world, in its actual position on the sky, with sizes, temperatures, and orbits.
• The Solar System up close: planets and major moons in NASA probe imagery, in visible light, ultraviolet, infrared, and radar. Rotate them to any angle.
FOR EVERYONE
• Kid Mode rewrites the whole tour for young explorers.
• Birthday Sky: a shareable card of the sky on the night you were born.
• Smart search: ask for exactly what you want.
Take the Stellar Tour!
