HD 125595 is a 9th magnitude K-type main sequence star located approximately 89 light years away in the constellation Centaurus. This star is smaller, cooler, dimmer, and less massive than our Sun. Also its metal content is 4% more than the Sun. In 2009, a gas giant planet was found in orbit around the star.

Planetary system

HD 125595 b is an extrasolar planet which orbits the star. This planet has at least 14 times the mass of Earth and takes 9 days and 16 hours to orbit the star at a semimajor axis of 0.081 AU.
