Set against a haunting, atmospheric soundscape, the app shows planets and satellites in their correct positions, and offers mini movies, facts and other related tidbits.” - TNW “This jaw-dropping app provides a wholly interactive 3D model of our solar system, one that’s had me hooked for days. It’s the kind of thing you can imagine a science teacher using in the classroom of the future — except that we don’t have to wait.” - CNet “Zoom from Mercury to Pluto (which makes the cut in this app), passing each planet’s moons along the way. Because Solar Walk knows what time it is, the planets are in proper orientation to the Sun: Earth is dark where it is currently night and gradually lightens to daytime on the other side.” - NY Times "It's great for showing my students the relative positions of the planets in the solar system, the satellites orbiting the Earth and our place in the galaxy. Awesome with a smartboard as well." - by jbrown61 Solar Walk enables you to: ► Observe the 3D model of our Solar system with all its objects in real time and in a proper orientation.

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.
