64 Andromedae, abbreviated 64 And, is a single^[6] star in the northern constellation of Andromeda. With a spectral type G8III, it is a deep-yellow coloured G-type giant approximately 419 light years from Earth with an apparent magnitude of 5.19.^[1] The star is moving closer to the Earth with a heliocentric radial velocity of –13 km/s.^[1]

This star is estimated to be 350^[5] million years old with a negligible rotation rate, showing a projected rotational velocity of 0.69 km/s.^[3] It has a little more than 3^[5] times the mass of the Sun and has expanded to 16^[5] times the Sun's radius. 64 And is radiating 136^[5] times the luminosity of the Sun from its enlarger photosphere at an effective temperature of 4,944 ^[5]
