62 Andromedae, abbreviated 62 And, is a single[12] star in the northern constellation Andromeda. 62 Andromedae is the Flamsteed designation; it also bears the Bayer designation of c Andromedae.[10] It is bright enough to be seen by the naked eye, with an apparent magnitude of 5.31. Based upon parallax measurements made during the Gaia mission, it is at a distance of roughly 273 light-years (84 parsecs) from Earth.[1] The star is moving closer to the Earth with a heliocentric radial velocity of −30 km/s,[5] and is predicted to come to within 144.6 light-years in 1,6 million years.[7]
This is an A-type main-sequence star with a stellar classification of A0 V.[13] Abt and Morrel (1995) gave it a class of A1 III,[14][7] matching a more evolved giant star. The star has 2.42[8] times the mass of the Sun, about 1.8[2] times the Sun's radius, and is spinning with a projected rotational velocity of 86 km/s.[8] It is radiating 45[8] times the Sun's luminosity from its photosphere at an effective temperature of 9,572 K.[8]
