Kepler186s

Kepler-186s is an exoplanet located in the Kepler-186 system, which is approximately 557 light-years from Earth in the constellation Cygnus. It is one of several planets orbiting the star Kepler-186, a late-type M dwarf star. Kepler-186s gained scientific interest due to its potential for habitability, as it resides within the star's habitable zone where conditions might allow for liquid water on its surface.

This exoplanet has a radius approximately 1.35 times that of Earth, classifying it as a super-Earth. Its orbital period is roughly 22 days, indicating it orbits closer to its star than Earth does to the Sun. Despite this, due to the lower luminosity of Kepler-186, the planet's surface temperature could potentially support liquid water, depending on its atmospheric composition.

Kepler-186s is part of a multi-planet system that includes Kepler-186b, c, d, and e. The system's architecture offers insights into planetary formation around low-mass stars. Observations suggest that planets in such systems tend to be rocky and similar in composition to terrestrial planets in our Solar System.

The discovery of Kepler-186s was announced by NASA's Kepler mission in 2014. The planet was detected through the transit method, where periodic dimming of the host star indicates the passage of a planet across its face. While the exact surface conditions and atmospheric composition of Kepler-186s remain unknown, ongoing research aims to assess its potential for habitability and its role in understanding exoplanetary systems around M dwarf stars.
