HD 12139 is a star in the constellation Andromeda. Its apparent magnitude is 5.81. Located approximately 47.01 parsecs (153.3 ly) distant, it is a white giant or subgiant of spectral type F0,[2] an intermediate-mass star that has used up its core hydrogen and is expanding. The star is suspected of being slightly variable, but this has not been conclusively proven.[3]
