HD 16175 b is an extrasolar planet located approximately 190 light-years away in the constellation of Andromeda, orbiting the star HD 16175. This planet masses 4.8 times that of Jupiter. However, the mass is only a minimum since the inclination of the orbit is not known. This planet orbits at about 2.2 astronomical units, taking 2.73 years to revolve around the star. The orbit of the planet is highly noncircular with an eccentricity at 0.64.[2]

Discovery

The discovery was made using radial velocity measurements taken between November 2004 and March 2009 with the Coudé Auxiliary and C. Donald Shane telescopes at Lick Observatory.[3]
