HD 106906 b is a directly imaged planetary-mass companion[2] and candidate exoplanet orbiting the star HD 106906, in the constellation Crux at about 336 ± 13 light-years (103 ± 4 pc) from Earth.[5] It is estimated to be about eleven times the mass of Jupiter and is located about 738 AU away from its host star.[4] HD 106906 b is an oddity; while its mass estimate is nominally consistent with identifying it as an exoplanet, it appears at a much wider separation from its parent star than thought possible for in-situ formation from a protoplanetary disk.[6]
