[9] It is located at a distance of 94 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −37.8 km/s.
[2] It is a K-type main sequence star with a stellar classification of K3 V[3] that is generating energy by the nuclear fusion of hydrogen at its core.
[10] Compared to the Sun, this star has an unusually high abundance of elements other than hydrogen and helium, what astronomers term the metallicity.
[5] Based upon high resolution measurements performed at the W. M. Keck Observatory and analysis performed upon these measurements by amateur astronomer Peter Jalowiczor, HD 218566 shows cyclical variations in radial velocity that suggest gravitational perturbation by orbiting companion.
This candidate object is estimated to be orbiting the parent star with a period of 225.7±0.4 days at an eccentricity of 0.3±0.1.
