Solar System vs TrueSize

Place the Sun on your table or on the floor and walk among the planets in augmented reality. Get close to Saturn's rings, look at Jupiter's moons from below, or find out how far away Pluto really is when the Sun is one metre wide. THREE WAYS TO SEE IT • Learn: everything fits in one room, so you can see every planet at once. • To scale: the planets' sizes are true to each other. Earth is 4 cm, Jupiter 45 cm, and Neptune is 30 metres from the Sun. • Real scale: everything to the same scale. Earth is a 9 mm marble 107 m away; Pluto is more than 4 km from you. Follow the labels to find them. WHERE THE PLANETS ARE TODAY Every planet starts at its real position in its orbit. Speed up time to watch the years pass, or tap Today to come back. REAL PHYSICS • Orbits with their true tilt: Pluto 17°, Eris 44° • Axes that always point the same way, which is what makes the seasons • Moons that always show the same face to their planet • Triton orbiting backwards, and Io, Europa and Ganymede in their 1:2:4 dance • Haumea, the dwarf planet shaped like a rugby ball 21 WORLDS The Sun, the eight planets, five dwarf planets and seven moons. Each one has a fact sheet with NASA figures — diameter, distance, length of the day and the year, temperature, gravity, moons, who discovered it — a size comparison with Earth and a surprising fact. Great for school, for curious minds of every age, and for anyone who has wondered how big space really is. Augmented reality needs an iPhone or iPad with ARKit. On other devices the app opens in 3D mode.

Explore the true size of countries, continents, and regions with TrueSize app. Move territories around an interactive map and compare their real proportions without the size distortion of traditional flat maps. Key Features • True-size comparisons Compare countries and regions using spherical geometry, without the size distortion caused by flat map projections. • 750,000+ geographic regions Explore countries, territories, states, provinces, historical borders, islands, and more. • Historical timeline Play through history or jump to any year, BC or AD, and watch borders, names, and flags change on the map. • Population tool Draw a circle anywhere on the map and see roughly how many people live inside it, along with the population density. • Languages and language families See the approximate areas where languages and language families are spoken, then move and compare them like any other region. • Natural features Explore mountains, peaks, deserts, islands, peninsulas, archipelagos, seas, bays, lakes, rivers, and river basins. • Geography games Play the TrueSize Challenge to guess the larger territory, or test your knowledge with the Flag Quiz. • Measurement tools Measure true geodesic distances in kilometers or miles, check compass bearings, and draw custom shapes. • Edit any boundary shape Modify the vertices of countries, regions, and other map shapes directly on the map. Add, move, select, or delete points with Undo and Redo support. • Facts and geographic details View population, area, flags, and useful facts for regions you explore. • Import & edit GeoJSON / TopoJSON files Load your own map data, modify shapes, simplify or merge boundaries, and export your changes. Ideal for students, educators, and GIS enthusiasts. • Share your discoveries Create and share interactive map comparisons with others. Perfect For • Students learning geography and map accuracy • Teachers explaining map projection distortion and how borders changed through history • Travelers visualizing distances and regions • Geography enthusiasts exploring historical and modern borders • Language lovers discovering where the world's languages are spoken • Anyone curious about the real scale of our world Why TrueSize? Traditional flat maps can significantly distort the apparent size of countries and regions, especially near the poles. TrueSize uses spherical geometry to provide more realistic size comparisons while letting you freely move and explore territories around the globe. From the creators of TrueSize.net, the official TrueSize app brings interactive geography tools, hundreds of thousands of regions, a historical timeline, population and language maps, games, measurements, and custom geographic data to your device. Rediscover the world as it truly appears – clearly, accurately, and interactively.
