HD 2767 is the primary component of a double star located 115 parsecs (380 ly) away in the constellation Andromeda. It is a red giant with a spectral type of K1III and an apparent magnitude of 5.88, thus is visible by the naked eye under favourable conditions.[2]

The secondary is named BD+32 81, has an apparent magnitude of 9.28, and is an F-type star; it shares radial velocity, parallax and proper motion with the primary component. The distance from the primary is estimated as 6,536 AU,[2] while their separation in the sky is 56 arcseconds.[4]
