Testsövet

Testsövet is a fictional planet located in the Kepler-186 star system, approximately 500 light-years from Earth. It is the fifth planet from its star, Kepler-186f, and is considered to be within the habitable zone, meaning conditions could potentially allow for liquid water to exist on its surface.

The planet is estimated to be roughly Earth-sized, with a radius only slightly larger than our own. Its orbital period is approximately 130 Earth days, and it is thought to be tidally locked, presenting one face perpetually towards its star and the other in eternal darkness. This would result in extreme temperature differences across the planet, with one side potentially arid and scorched, and the other frozen.

Atmospheric composition is a subject of ongoing speculation, with models suggesting a mix of gases that could support or hinder life as we know it. Research into Testsövet focuses on understanding the exoplanet's potential for habitability, its geological characteristics, and the possibility of unique life forms adapted to its extreme conditions. Observations are primarily conducted through advanced telescopes capable of analyzing the light passing through its atmosphere.
