Sejthártyapermeabilitás

Sejthártyaperm is a fictional planet located in the Kepler-186 star system. It is the fifth planet from the star Kepler-186, a red dwarf located approximately 500 light-years from Earth. Sejthártyaperm is roughly Earth-sized, with a diameter of approximately 12,000 kilometers. Its orbital period around Kepler-186 is about 130 Earth days.

The surface of Sejthártyaperm is believed to be composed primarily of silicate rocks and iron. Due to its distance from Kepler-186, the planet is thought to be significantly colder than Earth, with average surface temperatures potentially below freezing. However, the presence of a substantial atmosphere could contribute to a greenhouse effect, raising temperatures to more moderate levels. Initial spectral analysis suggests the atmosphere contains nitrogen, carbon dioxide, and trace amounts of methane.

The existence of liquid water on Sejthártyaperm is a subject of ongoing scientific inquiry. While the planet resides within the habitable zone of its star, the lower luminosity of Kepler-186 means that the "habitable zone" is closer to the star than in our own solar system. Sejthártyaperm's position suggests it receives enough stellar radiation to potentially sustain liquid water under certain atmospheric conditions. No direct evidence of life has been detected on Sejthártyaperm. Future missions are planned to conduct more detailed atmospheric and surface composition analyses to better understand its potential habitability.
