Stellar Tour is the ultimate guide to the cosmos. Point your device towards the night sky to explore any type of astronomical object: constellations, stars, exoplanet systems, galaxies, nebulae, planets, moons, and more.

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.

Truly Amazing App for Astronomy fans!

If you have a curiosity or already love Astronomy I couldn’t recommend this app more. It’s so detailed and well made. The animations are so smooth. And as you move your phone around the sky it’s so awesome to see in real time the things our eyes just don’t catch.

The developer helped improve the app with the kindness and professionalism that you wished every app developer had. Cheers to you Aaron, you have such a gift as an artist. I will buy any app you ever create in the future. Cheers!

Developer Response ,

Thanks for taking the time to give feedback. In the next release, there will be a way to turn off constellations. I’m not a fan of them myself (if that’s not clear from the text) but a lot of people have requested them.

In regards to the L-shaped black border, I haven’t seen anything like this in any of my testing. Apple makes many devices, so it’s possible you have one I haven’t tested on. If you could let me know which device you’re using, and maybe even send me a screen shot, that would be incredibly helpful in fixing this bug.

Also, if you have any feature requests, please send them my way.

For Space Lovers

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.

This app is amazing because you can get an in-depth look at planets in our own solar system AND exoplanets, which aren’t in a lot of other apps. The only reason I give it 4 stars is because you can’t zoom in much on the exoplanets, so it’s kind of hard to really get a good look. Otherwise it’s an amazing app and I would definitely recommend it to anyone who enjoys astronomy.
