Simbad=ADS+69HD 166 or V439 Andromedae (ADS 69 A) is a 6th magnitude star in the constellation Andromeda, approximately 45 light years away from
Earth . It is avariable star of the BY Draconis type, with a variation in brightness smaller than 0.2 magnitude. It is an orange star of thespectral type K0V, meaning it has a surface temperature of 3,500 to 5,000 kelvin and is adwarf star like ourSun , yet cooler and dimmer. It is within one degree of the starAlpha Andromedae . ["Autostar Suite Astronomer Edition". CD-ROM. Meade, April 2006.]It is located at Celestial (X,Y,Z) coordinates of 39.1, 1.13, 21.7 , Galactic (X,Y,Z) coordinates in ly: -14.1, 34.9, -24.1 and is found at Right Ascension and Declination: 0h6m36.75s, +29°1'17.6"
The star has a proper motion of 0.422 arcsec/yr (114.1° from north). The star has a Spectral class of K0e a Luminosity Class V. and an estimated visual luminosity of 59% of
Sol . The star has a diameter that is about 1.06 x Sol and has a Radial Velocity of -5.5 km/sec.The star is estimated to be 40 million years old.
The
habitable zone for anearth likeplanet would be about 0.77 A.U.s from thestar .References
