Zeténeks

Zeténeks is a fictional planet located in the Kepler-186 system, a star system approximately 500 light-years from Earth. It is the fifth planet from its star, Kepler-186f, and orbits within the habitable zone, suggesting the potential for liquid water to exist on its surface. The planet is estimated to be roughly 1.2 times the size of Earth.

Initial spectroscopic analysis of Zeténeks' atmosphere indicates the presence of nitrogen, oxygen, and trace amounts of methane. This composition has led to speculation about the possibility of biological activity, though no definitive evidence has been found. The planet's surface is believed to be varied, with potential for continents, oceans, and possibly polar ice caps. Its axial tilt suggests seasonal variations, similar to Earth.

The Kepler-186 system is comprised of five known planets, with Kepler-186f being the outermost and the only one confirmed to be within the habitable zone. Zeténeks' discovery was part of the broader Kepler mission, which aims to identify exoplanets, particularly those that could potentially support life. Further observations and analysis are required to better understand Zeténeks' geology, climate, and the true extent of its habitability. The planet remains a subject of interest for astrobiologists and astronomers researching exoplanetary environments.
