Iota Andromedae is a single[ 11] star in the northern constellation of Andromeda . It has the Flamsteed designation 17 Andromedae , while Iota Andromedae is the Bayer designation as Latinized from ι Andromedae. This object is visible to the naked eye at night as a faint, blue-white hued star with an apparent visual magnitude of +4.29.[ 2] parallax measurements, it is located approximately 500 light years distant from the Sun.[ 1]
This object is a B-type main-sequence star with a stellar classification of B8 V. It is among the least variable stars observed during the Hipparcos mission.[ 6] [ 4] [ 4] mass of the Sun and is spinning with a projected rotational velocity of 70 km/s.[ 9] [ 7] luminosity of the Sun from its photosphere at an effective temperature of 12,620 K.[ 8] debris disk candidate, showing an infrared excess at a wavelength of 18 µm.[ 12]
