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.
