Nu Andromedae is relatively faint in its own right, but it is important as being the nearest star to the Andromeda Galaxy that is visible to the naked eye. With Mu Andromedae, it forms the end of a line leading from the much brighter Mirach to the Galaxy itself. The spectral structure of Nu Andromedae's light marks it as a blue dwarf star, and also suggests that it might be part of a binary system, with a yellow companion star.
