Iota 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.

[6] The star is 116[4] million years old with 3.1[4] times the mass of the Sun and is spinning with a projected rotational velocity of 70 km/s.

[11] It is radiating 638[7] times the luminosity of the Sun from its photosphere at an effective temperature of 12,620 K.[10] The star is somewhat metal-poor, although the abundance of helium is close to solar.

[6] Iota Andromedae is a debris disk candidate, showing an infrared excess at a wavelength of 18 μm.

Consequently, the Chinese name for ι Andromedae itself is 螣蛇二十二 (Téng Shé èrshíèr, English: the Twenty Second Star of Flying Serpent).
