Star in the constellation Andromeda
12 Andromedae is a single[ 2] star in the northern constellation of Andromeda . The designation is from the star catalogue of English astronomer John Flamsteed , first published in 1712. It has an apparent visual magnitude of 5.87,[ 2] parallax shift of 23.7806[ 1] mas provides a distance estimate of 137 light years . The star is moving closer to the Sun with a radial velocity of −10.5 km/s.[ 5]
This is an ordinary F-type main-sequence star with a stellar classification of F5 V.[ 2] [ 6] projected rotational velocity of 12 km/s.[ 4] [ 7] [ 6] mass of the Sun and is radiating just over 7[ 3] Sun's luminosity from its photosphere at an effective temperature of around 6,454 K.[ 6]
