62 Andromedae is a single [12] star in the northern constellation Andromeda. [1] 62 Andromedae is the Flamsteed designation, abbreviated 62 And; [11] 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 pc) from Earth. [2] The star is moving closer to the Earth with a heliocentric radial velocity of −30 km/s, [6] and is predicted to come to within 144.6 light-years in 1.6 million years. [1]

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] [1] matching a more evolved giant star. The star has 2.42 [8] times the mass of the Sun, about 1.8 [3] 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] 62 And is about 57% of the way through its main sequence lifetime. [8]
