ADS 48 is a multiple star system in the constellation of Andromeda consisting of 7 stars. The components, in order from A to G, have apparent visual magnitudes of 8.826, 8.995,[2] 13.30,[12] 12.53, 11.68,[2] 9.949,[5] and 13.00.[13]

ADS 48A and ADS 48B are in orbital motion around each other while ADS 48F is a common proper motion companion not gravitationally bound to the pair. The others are unassociated background stars, and component C could be a double star itself.[14] It has also been proposed the existence of an unseen companion of 0.05 M☉.[10]
