HD 16175 is a 7th magnitude G-type star with temperature about 6000 K located approximately 189 light-years away[1] in the Andromeda constellation. This star is only visible through binoculars or better equipment. The absolute magnitude is 3.40, so it is 3.73 times more luminous than our local star at visible wavelength.
