Alien Planets
Read full descriptionHide full description
Alien Planets is a field guide to worlds that do not orbit our Sun. Somewhere out there, a year can last a few days, a sky can hold two suns, and a planet can be so close to its star that its surface is a permanent storm. This app turns those distant discoveries into something you can actually browse. Open it and move through confirmed exoplanets and the stars they circle. Each world comes with the details that make it real: how large it is, how massive, how long it takes to orbit, how far away it sits, and how it was found. Set a planet next to Earth or Jupiter and the scale snaps into place. A “super-Earth” stops being a label and starts looking like a place. The catalog keeps growing. New observations revise old numbers, and planets once listed as candidates become confirmed. Alien Planets stays with that living record, written in plain language, so you can follow the nearest known worlds, the strangest orbits, and the thin band astronomers call the habitable zone without getting lost in a research paper. Save the planets you want to come back to. Then keep going. The galaxy is full of new worlds, and most of them still have a story waiting.
