HD 125595
Star in the constellation Centaurus
HD 125595 is a star with a close Neptunian[6] companion in the southern constellation of Centaurus. With an apparent visual magnitude of 9.03,[2] this star is too faint to be viewed with the naked eye. It is located at a distance of 92 light years from the Sun based on parallax measurements, and is drifting further away with a radial velocity of +4.5 km/s.[1] The star has a high proper motion, traversing the celestial sphere and an angular rate of 0.57 arcsecond yr−1.[7]
This is an ordinary K-type main-sequence star with a stellar classification of K4V(k),[3] which indicates it is a small star that is generating energy at its core through hydrogen fusion. It is about eight[4] billion years old and is spinning with a projected rotational velocity of 1.5 km/s,[6] giving it a 37 day rotation period.[5] The star shows a moderate level of chromospherically activity due to star spots or plagues.[6] It is smaller, cooler, dimmer, and less massive than the Sun, but shows a higher atmospheric metallicity.[4]
