HD 106906 b

HD 106906 b is a directly-imaged planet and candidate exoplanet orbiting the star HD 106906, in the constellation Crux at about 300 light-years from Earth. It is estimated to be about eleven times the mass of Jupiter and orbits its primary at about 650 AU, or nearly 97 billion kilometres (60 billion miles). HD 106906 b is unique to science; 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.
