Gliese 179 b (also known asHIP 22627 b) is anextrasolar planet which orbits theM-typemain sequencestarGliese 179, located approximately 40light years away in theconstellationOrion. This planet has aminimum mass somewhat less than Jupiter and it orbits at 2.42AU from the star with an eccentricity slightly less thanPluto. The planetary distance ranges from 1.90 to 2.92 AU. This planet was discovered by using theradial velocity method fromspectrograph taken atKeck Observatory on November 13, 2009.[1] In 2023, the inclination and true mass of Gliese 179 b were determined viaastrometry.[2]
