Rasalnaqa

Rasalnaqa is a single star in the northern constellation of Andromeda. 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] Based upon parallax measurements, it is located approximately 510 light years distant from the Sun. 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. The star is 116 million years old with 3.1 times the mass of the Sun and is spinning with a projected rotational velocity of 70 km/s. It is radiating 638 times the luminosity of the Sun from its photosphere at an effective temperature of 12,620 K. The star is somewhat metal-poor, although the abundance of helium is close to solar. The latter excludes it from membership among the class of peculiar stars. Iota Andromedae is a debris disk candidate, showing an infrared excess at a wavelength of 18 μm.
