3D Solar System vs OrbitWatch

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.

Everything in orbit, live, in your hand. OrbitWatch tracks more than 18,000 real satellites and pieces of space debris using open orbital data, computed on your device with the same SGP4 math used by professionals — then turns it into an experience the whole family will fight over. ONE CONTINUOUS UNIVERSE Pinch from street level to the stars. Start at your own neighborhood in real satellite imagery, zoom out through the swarm of satellites circling Earth, keep going to a solar system where every planet sits at its true position today, then out to the Milky Way and our Local Group of galaxies — every stop labeled and explained for curious kids (and adults). WHAT'S ABOVE YOUR HOUSE — RIGHT NOW • My Sky lists every satellite above your horizon this second, with direction and distance. • 48-hour pass predictions for the ISS, Tiangong and your watchlist — with a VISIBLE badge when a pass will be sunlit against your dark sky, so you can actually step outside and see it. • Tap the bell and get a notification 10 minutes before a pass rises. POINT AT THE SKY (AR) Open Sky View and hold your phone up: satellites, their motion trails, the Sun, the Moon with its real phase, the planets and the brightest named stars appear exactly where they are in your sky, over your live camera. A compass ribbon keeps you oriented, and the FIND THE ISS arrow guides your hand until the station enters your view. STORIES THAT ACTUALLY HAPPENED Fly to the real debris of the 2009 satellite collision and watch it reenacted. See the missile tests that made the biggest debris clouds in history. Visit Hubble, the GPS constellation with its relativity-corrected atomic clocks, Starlink, Tiangong — plus a live feed of what launched in the last 30 days, in 2025, and in 2026, and what's about to fall back to Earth. VISIT THE PLANETS Tap any planet to fly to it: 8K NASA-imagery surfaces stream in as you zoom — skim Olympus Mons on Mars, or see Venus's hidden surface through radar. Kid-friendly fact cards on every world. BUILT TO RESPECT YOU No accounts. No ads. No tracking. Your location never leaves your phone — every calculation happens on-device.

Whether you're a space nerd, a parent with a curious kid, or someone who just saw a strange line of lights in the night sky — OrbitWatch tells you exactly what's up there.
