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.

Teia is an application that represents the solar system using 3D models. But, unlike the rest of the applications published in the stores, the objective of this application is to show the objects that this system is composed of by teaching perceptible and localizable curiosities on the surface of the planets. What are the rilles on the Moon? And the rupes on Mercury? Does Jupiter have a pearl necklace? Is really there a face on Mars? Why does Neptune have such an intense blue color? Learn every corner of the Solar System with this great collection of features spanning a total of over 40 pages, structured and developed by experts in the Planetary Astronomy field. The models represented have been designed taking care of the maximum possible realism, from the true color of the surface of Venus, to the structure of the ring systems. In this way, you have the feeling of visiting each planet only a few thousand kilometers away. The models represented are the following: * Mercury. * Venus. * Land. * Moon. * Mars. * Jupiter. * Saturn. * Uranus. * Neptune. Application developed by Himalaya Computing and Órbita Bianca.
