Gliese 581 d is the third planet in the Gliese 581 planetary system, and a potential planet that may indeed be terrestrial. Since Gliese 581 c, the previous planet in the system that was thought to be terrestrial, was discovered to be inhabitable, they found Gliese 581 d, and it is in the outer edge of the habitable zone.[2]
