záporn

Záporn is a fictional planet located in the Kepler-186 star system, approximately 500 light-years from Earth. It is the fifth and outermost known planet in its system, orbiting a red dwarf star. Záporn is classified as a terrestrial planet, meaning it is a rocky world with a solid surface. Its size is comparable to that of Earth, with a diameter approximately 1.1 times that of our planet.

The surface of Záporn is characterized by vast, arid plains and rugged mountain ranges. Evidence suggests that liquid water, while scarce, may exist in subsurface reservoirs. The planet possesses a thin atmosphere, primarily composed of nitrogen and carbon dioxide, with trace amounts of oxygen. This atmospheric composition results in a significantly colder surface temperature than Earth, with average temperatures hovering around -30 degrees Celsius.

Záporn has a single, small moon that orbits it at a relatively close distance. The planet's axial tilt is minimal, leading to negligible seasonal variations. Its orbital period around its star is approximately 130 Earth days. Due to the dimness of its red dwarf star, Záporn receives considerably less solar radiation than Earth. Consequently, the illumination on Záporn's surface is generally dimmer, with a reddish hue. While no complex life has been detected, the possibility of microbial life in protected subsurface environments remains an area of scientific interest.
