60 Andromedae is the Flamsteed designation for a star system in the northern constellation of Andromeda, located to the west-northwest of Gamma Andromedae. It is bright enough to be seen by the naked with an apparent visual magnitude of 4.82.[2] Based upon parallax measurements made during the Hipparcos mission, it is at a distance of roughly 530 light-years (160 parsecs) from Earth.[1]

This system is known to have three components. The primary is a giant star with a stellar classification of K3.5 III Ba0.4. It is being orbited by a white dwarf with a period of 748.2 days and an eccentricity of 0.34. There is a third component at an angular separation of 0.22 arcseconds.[3]
