HD 218566 [SEP] constellation
HD 218566
HD 218566 is a star in the equatorial zodiac constellation of Pisces. With an apparent visual magnitude of 8.6, this ninth magnitude star can not be viewed with the naked eye. However, it can be readily seen even with a small telescope.
HD 218566 is a smaller star than the Sun, with about 81% of the Sun's mass and 86% of the radius of the Sun. It is a K-type main sequence star with a stellar classification of K3 V that is generating
as and as far as from the Galactic Center. The orbital tilt carries this star as much as from the galactic plane.
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 days at an eccentricity of . The semi-major axis for this Keplerian orbit is an estimated 0.6873
