10 Andromedae, abbreviated 10 And, is an astrometric binary [3] star system in the northern constellation of Andromeda. 10 Andromedae is the Flamsteed designation. It has an apparent visual magnitude of approximately 5.81, [2] which means it is faintly visible to the naked eye. Based upon an annual parallax shift of 6.6 mas, [1] it is located 492 light years away. The system is moving toward the Earth with a heliocentric radial velocity of −1.1 km/s. [4]
The visible component is an aging red giant star with a stellar classification of M0 III, [2] which indicates it has consumed the hydrogen at its core and evolved off the main sequence. The measured angular diameter of this star, after correction for limb darkening, is 2.01±0.02 mas. [7] At the estimated distance of 10 And, this yields a physical size of about 33 times the radius of the Sun. [5] It is radiating 259 [2] times the Sun's luminosity from its enlarged photosphere.
