HD 95086 b, formally named Levantes,[2] is a confirmed,[5] directly imaged exoplanet orbiting the young, 17 Myr[6] A-class pre-main-sequence star HD 95086. It is roughly 5 times as massive as Jupiter and orbits about 70 AU away from the parent star. It was detected at thermal infrared wavelengths (3.8 μm) through direct imaging, using the NACO instrument on the VLT.[1] A debris disk has been detected in this system at submillimeter wavelengths and has been resolved in the far-infrared from data obtained with the Herschel Space Observatory.[7]

The host star was considered a highly probable member of the Lower Centaurus Crux star forming region,[8] until tentatively reassigned with 71% probability to the Carina association.[9] The star has a mass of 1.6 solar masses making it a late A type star. It is located approximately 90 parsecs away in the constellation of Carina.[10]
