NGC 7686 is a moderately-sized open cluster in the constellation Andromeda, containing about 80 stars. [2] At magnitude 5.6, it is an easy target for binoculars and small telescopes. [3] According to Johnson et al. (1961), the "color-magnitude diagram shows merely a uniform scatter with no significant tendency to show a cluster main sequence ...

HD 16028 is a star in the constellation Andromeda. Its apparent magnitude is 5.71. [2] Located approximately 225 parsecs (730 ly) distant, [1] it is an orange giant of spectral type K3III, [3] a star that has used up its core hydrogen and has expanded. Double star catalogues list two stars as optical companions.
