Artist's view of the exoplanet Gliese 581c. - Artist's view of the exoplanet Gliese 581c. Gliese 581c, with a radius of 1.5 times that of the Earth, is the first exoplanet gathering the necessary elements to imagine the existence of a possible extra-terrestrial life. With a mass of 5 times that of the Earth, an average temperature between 0 and 40* C, this exoplanet rotates around its star in just thirteen days and is located 14 times closer to its star than the Earth is to the Sun. But this star, Gliese 581, is a red dwarf, a star much smaller and less luminous than the Sun, so the position of this exoplanet is ideal for allowing the presence of water in liquid form on its surface
