3D Solar System vs Stellar Tour

Have you ever wanted to hold the Solar System in your hands? Now you can. 3D Solar System turns your device into a window to the planets, constellations, and stars beyond. Solar System in 3D and AR Travel from the Sun to the icy edge of deep space — a planetary journey of nearly 15 billion kilometers through our cosmic backyard. Study planets, moons, dwarf planets, and two major asteroid fields: the Asteroid Belt between Mars and Jupiter, and the Kuiper Belt beyond Neptune. See how tiny Earth looks next to Jupiter. Zoom in on planets' craters, spin Saturn's rings, and realize just how vast the universe really is. Interactive star map for passionate stargazers A complete map of the night sky with gyroscope support. Tilt your device toward the ceiling and explore constellations like a true space explorer — as if you were standing under a real night sky. Learn each constellation's name, its ancient stories, and the astronomy behind them. Learn to identify Orion, Ursa Major, Cassiopeia and discover dozens more. What you can do: ► Study planets — from scorched Mercury to icy Neptune — along with moons, dwarf planets, and bright constellations like a real astronomer. ► Test your knowledge with quizzes, planet order challenges, "True or False", and mythology questions. Learn who the planets are named after, how long a day lasts on Pluto, and what makes a star shine. ► Create your own planet using AI — design it, name it, and explore it. 714,000+ people have downloaded our app. To put that in perspective: that's 79 times more than all the stars you can see in the night sky with your own eyes. Some features may require a subscription. Free version includes: basic planet info, part of the constellation catalog, some quizzes and tests, star map, and AI planet generation (up to 2 planets). Subscription unlocks: full content about the Solar System, full constellation catalog, all quizzes and tests, planet cross-sections, unlimited AI planet generation. Every planet is different. Each constellation has a story. The universe is waiting — and it's bigger than you ever imagined. Explore all planets, learn every constellation, and become the space explorer you've always wanted to be. Start your journey through space today.

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: 1.7 billion real stars, every planet and major moon, eclipses, meteor showers, 13,000 deep-sky objects, and a course in astronomy that starts with the sky over your head and ends at the edge of the universe. 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 • 1.7 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, drawn from every star Gaia measured, with constellations, planets, and satellites overlaid on your live sky. • A sky that looks like the time it is: dawn, daylight, twilight, and full dark, with a real atmosphere and hazy ridges on the horizon. The Moon shows its earthshine, and Earth's night side its city lights. • Night Vision mode keeps your eyes dark-adapted with a pure red display. LEARN THE SKY • Sixteen short lessons, from the sky over your head to the edge of the universe. Every stop is a live visit: the lesson flies you to the star, steps the clock, or opens the tool it is talking about. The first three lessons are free. • Three reference books inside the app, How We Know, The Sky, and The Whole Story, with a glossary and dozens of labeled diagrams. SEVEN SKIES • See the stars the way Japan, China, Korea, Vietnam, India, and the Arabian desert saw them: their star figures and folk names drawn on your sky, their stories on each star's page, and their lunar festivals on the calendar. PLAN YOUR NIGHT • Sky Calendar: every eclipse, meteor shower, conjunction, and full moon, filtered by type. The week ahead is free; the full year comes with the expansion. • Night Planner: the best targets for your sky tonight, hour by hour. Sky Forecast: the cloud cover over your spot, hour by hour. • Reminders that fire only when something is worth stepping outside for, including ISS and Tiangong passes with a live countdown. • Home Screen and Lock Screen widgets for rise and set times and the next sky event. Ask Siri what is visible tonight. ECLIPSE EXPLORER Simulate any solar or lunar eclipse from any place on Earth: local timings, a disc animation of the Moon crossing the Sun, and a live countdown. The next solar eclipse at your own location is free: its times, what you will see there, and a reminder. 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. • Hubble and James Webb Space Telescope pictures, on the pages of the objects they show. FOR EVERYONE • Kid Mode rewrites the whole tour for explorers aged five to seven. • Birthday Sky: a shareable card of the sky on the night you were born. • Smart search: ask for exactly what you want. • Fifteen languages: English, Spanish, French, German, Italian, Portuguese, Russian, Japanese, Korean, Simplified and Traditional Chinese, Arabic, Hindi, Vietnamese, and Icelandic. Dates in your own calendar. • VoiceOver and Dynamic Type throughout. ONE PURCHASE, NO SUBSCRIPTION Cosmic Expansion adds the 1.7 billion stars, black holes up close, the exoplanets, the galaxies, the eclipses, the planner, the catalog, and the whole course in a single purchase that is yours forever.
