SIMBAD data

HD 167714, also known as HR 6837, is a solitary, orange hued star located in the southern circumpolar constellation Octans. It has apparent magnitude of 5.95, [2] allowing it to be faintly visible to the naked eye. Based on parallax measurements from Gaia, the object is estimated to be 359 light years distant. [1] With a heliocentric radial velocity of −13.9  km/s , [6] it is approaching the Solar System.

This is an evolved red giant with a stellar classification of K2 III. [4] It appears to be on the red giant branch, [3] generating energy by fusing a hydrogen shell around an inert helium core. At present it has 1.4 times the mass of the Sun [8] and at the age of two billion years, [10] it has expanded to 12.3 times its girth. [9] It shines with a luminosity 65 times greater than that of the Sun [8] from its enlarged photosphere at an effective temperature of 4,692  K . [9] HD 167714 has a near-solar metallicity [10] and is spinning slowly with a projected rotational velocity of 1.7  km/s . [11]
