Exoplanets are planets orbiting stars beyond our own solar system. This app allows you to explore all discovered exoplanets, their measured physical properties, their location in the night sky, and their host stars. An interactive model shows you the entire observable universe, all the way from the surface of the Earth to the cosmic microwave background. This app has been developed by a professional astronomer. Main features: * Interactive visualizations and animations. * Physical properties of all detected exoplanets and their host stars, updated on a daily basis. * Stunning 3D model of our Milky Way showing the location of all known exoplanets. You can zoom into any planetary system, explore how the night sky and the constellations look from the surface of other planets, or zoom out and see other local galaxies and galaxy clusters as well as the cosmic microwave background. * Visualizations of exoplanet orbits and the habitable zone. * Choose between the Open Exoplanet Catalogue, the NASA Exoplanet Archive, and the Extrasolar Planet Encyclopedia (exoplanet.eu). * Push notifications are sent out whenever a new planet is discovered. * Augmented reality sky map: point the phone towards the sky to find an exoplanet! * Interactive multi-touch correlation plots. * Solar System planets, major moons, and asteroids are included. * Explore S-Stars orbiting the black hole at the Galactic Center of our Milky Way * Background information about exoplanets and detection methods. * Full support of planets in binary, triple, quadruple systems and orphan planets. * Real-time ray tracing on the GPU.

Solar System Scope is a fun way of Exploring, Discovering and Playing with the Solar System and Outer Space. Solar System Scope (or just Solar) contains many views and celestial simulations, but most of all - it brings you closer to the furthest reaches of our world and lets you experience lots of fantastic space sceneries. It aspires to be the most illustrative, easy to understand and simple to use space model. - 3D Encyclopedia In Solar’s unique encyclopedia you will find the most interesting facts about every planet, dwarf planet, every major moon and more – and everything is accompanied by realistic 3D visualizations. Solar’s encyclopedia is available in 10 languages: English, Spanish, German, Russian, Italian, Korean and Slovak. More languages are coming soon! - Nightsky Observatory Enjoy Stars and constellation of the night sky as viewed from any given location on Earth. You can point your device at the sky to see all objects in their proper place, but you can also simulate Night sky in the past or in the future. Now with advanced options that let you simulate ecliptic, equatorial and azimuthal line, or grid (among other things). - Scientific Instrument Solar System Scope calculations are based on up-to-date orbital parameters published by NASA and let you simulate celestial positions at any given time. - For Everyone Solar System Scope is well suited for all audiences and ages: It is enjoyed by space enthusiasts, teachers, scientists, but Solar is successfully used even by children of 4+ years of age! - Unique Maps We are proud to present a very unique set of planetary and moon maps, that let you experience a true-color space as never before. These accurate maps are based on NASA elevation and imagery data. Colors and shades of the textures are tuned according to true-color photos made by Messenger, Viking, Cassini and New Horizon spacecrafts, and the Hubble Space Telescope. Basic resolution of these maps is for free – but if you would like the best experience, you can check out the highest quality, which is available with In-App purchase. - Join our vision Our vision is to build the ultimate space model and bring you the deepest space experience. And you can help - try Solar System Scope and if you like it, spread the word! And don’t forget to join the community and vote for new features on our homepage.
