Due to its mass of at least 3.6 times the mass of Earth, HD 85512 b is classified as a rocky Earth-size exoplanet (< 5M🜨) and is one of the smallest exoplanets discovered to be just outside the inner edge of the habitable zone.[1] HD 85512 b, along with Gliese 581 d, was once considered to be one of the best candidates for habitability in 2011.[4]
