HD 16175 is a 7th magnitude G-type star with temperature about 6000 K located approximately 190 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.

Planetary system

The extrasolar planet HD 16175 b was published in the June 2009 issue of the Publications of the Astronomical Society of the Pacific.[4]
