Gliese 179 b

Gliese 179 b (also known as HIP 22627 b) is an extrasolar planet which orbits the M-type main sequence star Gliese 179, located approximately 40 light years away in the constellation Orion. This planet has a minimum mass somewhat less than Jupiter and it orbits at 2.42 AU from the star with an eccentricity slightly less than Pluto. The planetary distance ranges from 1.90 to 2.92 AU. This planet was discovered by using the radial velocity method from spectrograph taken at Keck Observatory on November 13, 2009. In 2023, the inclination and true mass of Gliese 179 b were determined via astrometry.
