5 Andromedae is a single, [8] yellow-white hued star in the northern constellation of Andromeda, abbreviated 5 And. [1] 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. [1] Based upon an annual parallax shift of 29.1 [2]   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. [1] It has a relatively high proper motion, advancing across the celestial sphere at the rate of 0.201  arc seconds per year. [9]

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. [6] The star has 1.39 [4] times the mass of the Sun and 1.74 times the Sun's radius. [5] It is radiating 5.6 [1] 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.
