}}{{Starbox end}}13 Andromedae, abbreviated 13 And, is a single,[16] blue-white hued variable star[6] in the northern constellation of Andromeda. 13 Andromedae is the Flamsteed designation, while it bears the variable star designation V388 Andromedae. With a typical apparent visual magnitude of around 5.75,[3] it is dimly visible to the naked eye under good seeing conditions. The distance to this star can be directly estimated from its annual parallax shift of {{Val|10.9|ul=mas}},[1] yielding a range of 300 light years. At that distance, its brightness is diminished by an extinction of 0.13 magnitude due to interstellar dust.[11] The star is moving closer to the Earth with a heliocentric radial velocity of −8 km/s.[7]This is a magnetic chemically peculiar star that has been assigned stellar classifications of B9 III or B9 Mn.[4] It is a variable star of the Alpha2 Canum Venaticorum type, ranging in magnitude from 5.73 down to 5.77[6] with a period of 1.47946 days.[4] The star has a high rate of spin, showing a projected rotational velocity of 75 km/s.[13] 13 Andromedae is around 345[11] million years old and shines with 43[3] times the Sun's luminosity.
