HD 175167
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. 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. It shows a high proper motion, traversing the celestial sphere at an angular rate of 0.190 arcsec yr−1.

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