Gliese 581c is an exoplanet located approximately 20 light-years away from Earth in the Libra constellation. It orbits the red dwarf star Gliese 581 and has a mass of roughly five times that of Earth. Its surface temperature is estimated to be within the range that allows for liquid water, which suggests that it could potentially support life. However, its close proximity to its parent star might lead to tidal locking, causing one side to be extremely hot while the other remains in perpetual darkness.
