'''HD 85512''' is a solitary [[K-type main-sequence star]] located approximately 36 light-years away in the constellation [[Vela (constellation)|Vela]]. It is approximately one billion years older than the [[Sun]]. It is extremely [[chromosphere|chromospherically]] inactive, only slightly more active than [[Tau Ceti]]. The star is known to host one low-mass planet.

On August 19, 2011, a ≥3.6 [[Earth mass|Earth-mass]] planet was discovered using [[HARPS]] that is "just inside" the [[habitable zone]], along with the planets of [[82 G. Eridani]] and [[HR 7722 c]].<ref name="Pepe2011"/> The planet could be potentially cool enough to host liquid water if the planet exhibits more than 50% cloud coverage. HD 85512 b is currently the fifth best candidate for habitability according to the [http://phl.upr.edu/projects/habitable-exoplanets-catalog Habitable Exoplanets Catalog].
