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.

Verdict
The clearest difference is review sentiment: Exoplanet at 91% against NASA Spinoff's 0%. Exoplanet also leads on rating (4.7 vs 3.0) and update cadence (every 2 weeks vs every 12 months). NASA Spinoff's advantage is in-app purchases (none vs 7) and iOS requirement (7.0 vs 13.0). On price and ads there is nothing between them.
