HD 85512 b
HD 85512 b is an exoplanet orbiting Gliese 370, a K-type main-sequence star approximately 36 light-years from Earth in the constellation of Vela.
Due to its mass of at least 3.6 times the mass of Earth, HD 85512 b is classified as a near Earth sized 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, but its habitability is now disputed due to PHL's redefinition of the Habitable Zone.
Detection and discovery
HD 85512 b was discovered by scientists at University of Geneva, Switzerland, led by Swiss astronomer Stéphane Udry of the Guaranteed Time Observations (GTO) program of High Accuracy Radial velocity Planet Searcher (HARPS), a high-precision echelle spectrograph installed on ESO's 3.6 m telescope at La Silla Observatory in Chile. The team used the Doppler spectroscopy technique which determines the minimum mass of the planet through slight changes in motion of the parent star. It was discovered on August 17, 2011.
HD 85512
HD 85512 is a solitary K-type main-sequence star located approximately 36 light-years away in the constellation Vela. It is approximately one billion years older than the Sun. It is extremely chromospherically inactive, only slightly more active than Tau Ceti. The star is known to host one low-mass planet.
Planetary system
On August 19, 2011, a ≥3.6 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. 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 Habitable Exoplanets Catalog.
