Atllä

Atllä is a fictional planet located in the Kepler-186 system. It is the fifth and outermost known planet orbiting the star Kepler-186, a red dwarf. Atllä is roughly Earth-sized and resides within the habitable zone of its star, meaning it could potentially support liquid water on its surface.

The planet's atmosphere is believed to be denser than Earth's, composed primarily of nitrogen and carbon dioxide, with trace amounts of oxygen. This composition contributes to a warmer surface temperature than would otherwise be expected given its distance from the star. Surface observations, though limited, suggest a varied topography including vast oceans, continental landmasses, and mountain ranges. Evidence points to a significant amount of volcanic activity shaping the planet's crust.

Life on Atllä, if it exists, is hypothesized to be adapted to the dimmer light conditions of its red dwarf star. Photosynthetic organisms may utilize infrared wavelengths more efficiently. The planet's axial tilt is thought to be minimal, resulting in less pronounced seasonal variations compared to Earth. Further research and observation are required to fully understand the characteristics and potential habitability of Atllä. Its discovery has fueled ongoing scientific interest in the search for exoplanets and extraterrestrial life.
