6,000+ confirmed exoplanets from leading scientific archives. Compare alien worlds, explore habitable zones, and track the latest discoveries.
Explore the universe of exoplanets — over 6,000 confirmed worlds orbiting distant stars, updated from leading scientific archives. Track new discoveries as they happen and dive into the data behind every planet.
EXPLORE THE COSMOS
Search, filter, and sort the complete catalogue of confirmed exoplanets. Find planets by discovery method, star type, orbital characteristics, or habitability potential. Every entry includes detailed scientific data from peer-reviewed sources.
ATMOSPHERIC SPECTRA
Browse JWST and Hubble transmission spectra for planets where atmospheric data is available. Toggle molecular overlays for CO2, CH4, H2O, CO and more to see which absorption features have been detected.
3D SYSTEM VIEW
Step into a planetary system in 3D — see each planet's orbit around its host star with realistic shading and a visualisation of the habitable zone. On iPhone and iPad you can also place a system into your environment in AR.
COMPARE WORLDS
Analyze exoplanets side-by-side — or compare them with Solar System planets like Earth, Jupiter, and Mars. Compare sizes, masses, orbital periods, star properties, and habitability scores to understand what makes each world unique.
HABITABLE ZONE VISUALIZATION
See exactly where planets orbit within their star's habitable zone — the region where liquid water could exist. Identify potentially Earth-like worlds and understand the conditions for life beyond our solar system.

This should be a core app for anyone who ever wondered if we are alone in the universe. The ever growing list of planets and systems beyond our star is breathtaking. The app is easy to use and regularly updated so you’ll never miss a new neighbor. Scientists and Astronomers of all ages should have this on their phones. You qualify if you ever looked up and said “I wonder …”

Wish there was the option for a one time fee for premium features
Zueszilla_SpaceCat
This is a fantastic app. Although I do wish there was a one time fee for premium features. I’d gladly pay $15-$20 for premium features one time but I can’t bring myself to pay on a subscription basis.
Interactive star map
QuantumMan01
I am using an Apple iPad. The interactive star map doesn’t work. I hope there is a fix for this, in the near future. Does it only work on the earlier versions of Exoplanet Explorer HD.
NEW IN 3.3.3:
• Fixed a crash that could happen when viewing a planetary system in AR mode
