HD 175167
Star in the constellation Pavo / From Wikipedia, the free encyclopedia
HD 175167 is a star with an exoplanet companion in the southern constellation of Pavo. It is too faint to be visible with the naked eye at an apparent visual magnitude of 8.01.[2] The system is located at a distance of 232 light-years from the Sun based on parallax measurements, and it is drifting further away with a radial velocity of 5 km/s.[1] It shows a high proper motion, traversing the celestial sphere at an angular rate of 0.190 arcsec yr−1.[9]

This yellow-hued star has a stellar classification of G5IV/V,[3] which, together with the star's absolute magnitude of 3.88,[2] is consistent with a star that is in the early stages of evolving off the main sequence.[10] It has a high metallicity and is spinning with a projected rotational velocity of 2.6 km/s.[7] The star has 1.2[4] times the mass of the Sun and 1.75[5] times the Sun's girth. It is radiating 2.9[6] times the Sun's luminosity from its photosphere at an effective temperature of 5,635 K.[4]
