Kepler 186 Planets Probability to Host Life
Kepler 186 V (Terminus): The chances of life on Kepler 186 V are currently unknown, though it is a promising habitable planet candidate because it is a Super Terran size planet in its star's habitable zone. However, scientists are uncertain about its atmosphere and surface temperature, with possibilities ranging from being too cold for life to a Venus-like hellscape. While its location and size offer potential, further data on its atmospheric composition and other factors are needed to determine its true habitability.

The planet Kepler 186 V might be habitable, but much more research needs to be done to characterize its atmosphere. In addition, the planet is susceptible to extreme flares from the Kepler 186 star, which makes it challenging to hold on to an atmosphere, and for life to thrive.
