45 Andromedae, abbreviated 45 And, is a double star[9] in the northern constellation Andromeda. 45 Andromedae is the Flamsteed designation. Its combined apparent visual magnitude is 5.80.[2] Based upon an annual parallax shift of 9.57 mas,[1] it is located 341 light years away.
The stellar classification of 45 And is B7 III-IV,[3] matching an evolving subgiant/giant star. It has about 5.2[5] times the Sun's radius and is radiating 414[2] times the Sun's luminosity from its photosphere at an effective temperature of 12,874 K.[6]
This star is most likely single. A companion star was discovered by American astronomer George W. Hough in 1890. As of 2006, the companion was at an angular separation of 0.10″ along a position angle of 225° from the primary.[9]
