5 Andromedae is a single,[7] yellow-white hued star in the northern constellation of Andromeda. Its designation comes from a catalogue of stars by English astronomer John Flamsteed, published in 1712. The star is faintly visible to the naked eye, having an apparent visual magnitude of 5.68.[2] Based upon an annual parallax shift of 29.12[1] mas as seen from Earth, it is located 112 light years away. 5 Andromedae is moving closer to the Sun with a radial velocity of −2.6 km/s.[2] It has a relatively high proper motion, advancing across the celestial sphere at the rate of 0.201 arc seconds per year.[8]

This is an ordinary F-type main-sequence star with a stellar classification of F5 V.[3] It is estimated to be 2.3[4] billion years old and is spinning with a projected rotational velocity of 9.7 km/s.[5] The star has 1.39 times the mass of the Sun. It is radiating 5.6[2] times the Sun's luminosity from its photosphere at an effective temperature of about 6,605 K.[4]

Within Andromeda it is the second of a northerly chain asterism – 7, 8, 11 are further south-westward, with 3 Andromedae in the other direction.
