Stellar Tour is the only AR stargazing app written by an astrophysicist. Become an expert on exoplanets, stars, the planets and moons of our Solar System, galaxies, nebulae, and more.

Stellar Tour is the ultimate guide to the cosmos. Point your device towards the night sky to explore any type of astronomical object. 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!
