Star in the constellation Andromeda
3 Andromedae , abbreviated3 And , is a single[ 10] star in the northernconstellation ofAndromeda .3 Andromedae is theFlamsteed designation . It is visible to the naked eye with anapparent visual magnitude of 4.64.[ 2] parallax shift ofmas [ 1] light years . It is moving closer to the Earth with a heliocentricradial velocity of −35 km/s,[ 11] proper motion , traversing thecelestial sphere at″ −1 .[ 12]
This is anevolved giant star with astellar classification of K0 IIIb,[ 4] red clump star,[ 3] helium fusion at itscore . This star has an estimated 1.7[ 5] mass of the Sun (M ☉ ), and, at the age of 2.3[ 5] Sun's radius (R ☉ ).[ 6] [ 5] Sun's luminosity from its enlargedphotosphere at aneffective temperature of 4,668 K.[ 5]
