Záridn

Záridn is a fictional planet located in the Kepler-186 system. It is the fifth and outermost known planet orbiting the red dwarf star Kepler-186, approximately 500 light-years from Earth. Záridn is a terrestrial planet, meaning it is rocky and has a solid surface. Its estimated radius is similar to that of Earth, and its mass is also thought to be comparable.

The planet's orbital period around Kepler-186 is approximately 130 Earth days. Due to its distance from the star, Záridn resides within the habitable zone, the region where conditions might be suitable for liquid water to exist on the surface. However, the light from Kepler-186 is significantly dimmer and redder than sunlight, which would affect any potential plant life, likely requiring different photosynthetic pigments.

The surface conditions on Záridn are largely unknown. Scientists speculate about the presence of an atmosphere, which would be crucial for regulating temperature and potentially shielding the surface from radiation. The composition of this atmosphere, if it exists, is also a matter of conjecture. Research into exoplanets like Záridn aims to understand the diversity of planetary systems and the potential for life beyond Earth. Continued observation and advancements in telescope technology may one day provide more detailed information about this distant world.
