HD 222806

HD 222806 (HR 8995) is a suspected astrometric binary in the southern circumpolar constellation Octans. It has an apparent magnitude of 5.74, allowing it to be faintly seen with the naked eye. Parallax measurements place the system at a distance of 565 light years and it is currently receding with a heliocentric radial velocity of $$.

The visible component has a stellar classification of K1 III, indicating that it is a red giant. At present it has 126% the mass of the Sun, but has expanded to almost 19 times its girth. It radiates at 151 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of $$, giving it an orange hue. HD 222806 is metal enriched with an iron abundance over twice that of the Sun and is believed to be a member of the young disk population. It spins with a projected rotational velocity lower than $$.
