HD 1606 is a single[14] star in the northern constellation of Andromeda, positioned a few degrees to the northeast of the bright star Alpheratz. It has a blue-white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.87.[3] Although it is suspected of variability, none has been conclusively found.[15] The star is located at a distance of approximately Script error: No such module "convert". from the Sun based on parallax,[2] and is drifting further away with a radial velocity of +4 km/s.[8] It has an absolute magnitude of −0.5.[9]

This is a B-type main-sequence star with a stellar classification of B7V,[5] which means it is currently generating energy through hydrogen fusion at its core. It has 3.75[4] times the mass of the Sun and a fairly high rate of spin, showing a projected rotational velocity of 113 km/s.[11] The star is radiating 245[4] times the luminosity of the Sun from its photosphere at an effective temperature of 13,186 K.[11]
