Alteias
Alteias is a fictional planet located in the Kepler-186 star system, approximately 500 light-years from Earth. The planet is roughly Earth-sized, with estimates suggesting a diameter of 1.1 times that of Earth. It orbits within the habitable zone of its M-class red dwarf star, Kepler-186. This orbital position means Alteias potentially receives enough stellar radiation to support liquid water on its surface, a key ingredient for life as we know it.
The atmosphere of Alteias is believed to be composed primarily of nitrogen and oxygen, with trace amounts
Vegetation, characterized by its deep red and purple hues, is thought to cover much of Alteias' landmasses.
