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.
