Avenile

Avenile is a fictional planet located in the Kepler-186 star system. It is the fifth and outermost known planet orbiting the red dwarf star Kepler-186, approximately 500 light-years from Earth. Avenile was discovered by the Kepler space telescope in 2014, and its existence was confirmed through follow-up observations.

The planet is notable for being roughly Earth-sized, with an estimated radius of 1.1 times that of Earth. It orbits within the habitable zone of its star, meaning it receives an amount of stellar radiation that could potentially allow for liquid water to exist on its surface. However, as Kepler-186 is a red dwarf star, Avenile receives less light than Earth does from the Sun, and its surface temperature would be significantly cooler.

Further details about Avenile's atmosphere, composition, and potential for life remain unknown due to the vast distance. Scientists are actively studying exoplanets like Avenile to understand the diversity of planetary systems and the conditions necessary for habitability. The discovery of Earth-sized planets in habitable zones around other stars is a key objective in the search for extraterrestrial life.
