Every Planet vs SpaceUtil

Every Planet turns the whole observable universe into something you can hold in your hand. Tap once and the World Forge builds a planet that has never existed before: an ocean world wrapped in cloud, a ringed gas giant, a lava world cracked with light, a frozen wanderer far from its star. Every world is unique and generated from a single seed, so the one you just made is one you will never see again unless you keep it. The worlds are imagined. The physics behind them is not. Every planet carries an honest science dossier. Its year is computed with Kepler's third law. Its warmth comes from the real luminosity of its star and the greenhouse effect of its air. You see its distance from Earth, the year your light would arrive, the length of its day, its host star's temperature, and whether liquid water is even possible. Estimates carry honest uncertainty, the way real astronomy does. WHAT YOU CAN DO Forge a world Make a new world in a tap, or aim the Forge toward what you want to find: water, a giant, two suns, or simply something strange. Keep the ones worth keeping Save a world to your Archive, give it a name, and write a note about why you stopped there. Unsaved worlds are gone the moment you move on, so the good ones are worth catching. Read the real science Open any world's dossier for a plain, careful explanation of its orbit, star, mass, and light, tied back to the methods astronomers actually use. Learn the universe, and remember it The Observatory holds short daily recall questions built on spaced repetition, so real ideas actually stick. Track a gentle streak and watch how much of the sky feels familiar. Travel outward Every discovery carries you about eight percent deeper into space, past real landmarks, all the way to the edge of the observable universe. Go deeper in the Observatory An orbit lab to move a world through space, a field guide to the stars that make planets possible, an atlas of twelve genuinely strange real worlds, a guide to how we find planets we cannot see, and the big numbers that put it all in scale. QUIET BY DESIGN No account. No ads. No tracking. Everything you make stays on your device. Optional ambient audio for the long trip outward. Built to be calm, factual, and yours. There are around seven hundred quintillion rocky planets out there. Humanity has confirmed about six thousand. Every Planet is a small, honest way to feel that scale, one world at a time.

SpaceUtil brings the whole sky into one app: an AR star map, a 3D solar system, live ISS tracking and the current position of the Voyager probes. No account, and almost everything is computed on your device without an internet connection. AR STAR MAP Point your phone at the sky and the stars and constellations in that direction appear on screen. 120,000 stars, all 88 constellations with lines, names and artwork, an AR mode that overlays the camera, and a red night mode. Search for a star, planet or constellation and an arrow guides you to it. Rewind or fast-forward time to see the sky on any date. 3D SOLAR SYSTEM An orrery with the Sun, the eight planets and major moons in their real positions. Rotate and zoom with your fingers, tap a planet for its story. Live distances to each planet, Jupiter's four big moons, Saturn's rings, conjunctions and alignments. LIVE ISS TRACKER See where the International Space Station is right now on a 3D globe and a world map, updated every second. Visible pass predictions for your location with time, direction and altitude, plus a sky-path view. WHERE ARE VOYAGER 1 AND 2? Follow the two farthest human-made objects on a 3D map of the solar system with their current distance from Earth. Computed on your device from NASA/JPL reference data. TONIGHT A briefing on tonight's observing conditions from the moon phase and twilight times, with the top 5 objects to look at now. Sun, moon and planet rise and set times; civil, nautical and astronomical twilight. MOON, ECLIPSES, METEOR SHOWERS Moon phase calendar and lunar age, upcoming solar and lunar eclipses, every major meteor shower with its peak night and how bright the moon will be. ASTROPHOTOGRAPHY HELPERS 500-rule exposure calculator, Milky Way planner, golden and blue hour, moonrise direction. LEARN AND PLAY Constellation myths, a space quiz, the sky on your birthday, light travel time, light-year/AU/parsec converter, an exoplanet catalog, an observation log with badges. PRIVACY Location is used only on the device to align the sky map, and the AR camera image is never captured, stored or sent anywhere. No account, no cloud.
