Star in the constellation Aquarius
64 Aquarii is a star located 312 light years away from the Sun in the zodiac constellation of Aquarius . 64 Aquarii is its Flamsteed designation . With an apparent visual magnitude of 6.93,[ 2] it is too faint to be readily visible to the naked eye. The star is moving further from the Earth with a heliocentric radial velocity of +11 km/s.[ 4]
The stellar classification for this star is G2/3 IV/V,[ 3] which indicates the spectrum displays mixed traits of a G-type main-sequence star and a more evolved subgiant star . It is 2.6 billion years old and is spinning with a projected rotational velocity of 8.75 km/s. The star has 1.45 times the mass of the Sun and 2.8 times the Sun's radius .[ 5] It is radiating 13[ 1] times the luminosity of the Sun from its photosphere at an effective temperature of 5,926 K.[ 5]
