It has an apparent visual magnitude of 6.01, which makes it a challenging target to view with the naked eye in suitably dark skies. Based upon an annual parallax shift of 3.72 mas, the distance to this star is approximately 880 light-years (270 parsecs).Eta Aquarii has a stellar classification of B9 IV-Vn, which may indicate that it is beginning to evolve away from the main sequence into a subgiant as the supply of hydrogen at its core becomes exhausted. At present it has an estimated 2.8 times the radius of the Sun, but this will increase as it continues to evolve into a giant star. Eta Aquarii is spinning rapidly with a projected rotational velocity of 249 km/s. This motion, combined with the Doppler effect, is causing the absorption lines in the spectrum to spread out and become 'nebulous', as indicated by the 'n' suffix in the classification.. }
