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. HD 85512 b, along with Gliese 581 d, was once considered to be one of the best candidates for habitability in 2011.
