Augmented reality view of 1000s of exoplanet systems, plus the planets and moons of the Solar System. Astrophysicist Dr. Aaron Day provides a tour guide for alien worlds, rather than the standard inundation of random facts as if collected from a boring old encyclopedia. Stellar Tour tells the scientifically accurate tale of the conditions on the ground, in the seas, or floating through the clouds of the Solar System.

Exoplanet systems are displayed in their actual location on the sky. Exoplanet sizes, temperatures, and orbits are given for nearly all known exoplanets.

Using images collected up close by NASA's many probes, all the planets and major moons of the Solar System are displayed in exquisite detail. Planets and moons can be rotated and viewed from any angle. High resolution images are displayed in vibrant color, representing not just visible light, but ultra violet, infrared, and even radar when available.

Take the Stellar Tour!

Images are provided by NASA, JPL, Lsmpascal, and others. Credits are given with the captions of each image.

For Space Lovers

Lizzie Margaret

Very cool and informative. The app features a 3D interactive map of the solar system that is both user-friendly and fun. It also contains many pictures and educational material about each planet. Both the casual space enthusiast and the hardcore space nerd will find something to love about this app---or really anyone that has ever gazed into the night sky with a sense of curiosity or wonder.

Awesome and informative


Unlike other free apps out there on the solar system , Stellar Tour delivers on both the 3D graphics aspect as well as the information content. My favorite aspect of the app is the style of the educational text. Instead of boring me with dry facts, I feel like I am transported to the surface of each moon and planet.
