Lemnia

Lemnia is a fictional planet located in the Kepler-186 system, approximately 500 light-years from Earth. It is the fifth planet orbiting the red dwarf star Kepler-186, and is notable for being the first Earth-sized planet discovered in the habitable zone of another star. This means that conditions on Lemnia could potentially allow for the existence of liquid water on its surface, a key ingredient for life as we know it.

The planet is estimated to be roughly 1.1 times the size of Earth, with a similar mass. Its orbit around Kepler-186 is much tighter than Earth's orbit around the Sun, taking approximately 130 Earth days to complete a year. Due to its distance from a red dwarf star, Lemnia receives less light than Earth, but its closer proximity to its star compensates for this. Scientists believe that Lemnia may be tidally locked, meaning one side perpetually faces its star while the other remains in darkness. This would create extreme temperature differences across the planet.

While the presence of an atmosphere and liquid water are speculative, the discovery of Lemnia has fueled scientific interest in the search for exoplanets and the possibility of extraterrestrial life. Further observations and advancements in telescope technology are needed to determine the precise atmospheric composition and surface conditions of Lemnia. The planet's designation within the Kepler-186 system signifies its importance in exoplanetary research.
