59 Andromedae, abbreviated 59 And, is a sixth-magnitude binary star system in the northern constellation of Andromeda. 59 Andromedae is the Flamsteed designation. As of 2017, the pair had an angular separation of Script error: No such module "val". along a position angle (PA) of 36°. Compare this to a separation of Script error: No such module "val". along a PA of 35°, as measured in 1783.[11] The two stars have an estimated physical separation of Script error: No such module "val"..[5]

The magnitude 6.09[2] primary component is a B-type main-sequence star with a stellar classification of B9 V.[3] It has 2.73[5] times the Sun's radius and is radiating 84 times the Sun's luminosity from its photosphere at an effective temperature of 10,870 K.[6] It is spinning with a projected rotational velocity of 176 km/s.[3]

The secondary is a magnitude 6.82[2] A-type main-sequence star with a class of A1 Vn,[3] where the 'n' suffix indicates "nebulous" lines due to rapid rotation. It is spinning with a high projected rotational velocity of 233 km/s.[3] The star has 2.23[7] times the Sun's mass and 2.59[5] times the Sun's radius. It is radiating 30[7] times the luminosity of the Sun and has an effective temperature of 9,498 K.[6]
