22 Aquilae, abbreviated 22 Aql, is a star in the equatorial constellation of Aquila. 22 Aquilae is its Flamsteed designation. It is a faint star but visible to the naked eye with an apparent visual magnitude of 5.59.^[2] The distance to 22 Aql can be estimated from its annual parallax shift of 4.74 mas,^[1] which yields a separation of 690 light years. It is moving closer to the Earth with a heliocentric radial velocity of −23 km/s.^[5]

Cowley et al. (1969) assigned this star a stellar classification of A3 IV,^[4] matching an evolving subgiant star that has exhausted the hydrogen at its core. Houk and Swift (1999) reassigned it as an A-type main-sequence star with a class of A1 V.^[3] It has nearly three times the mass of the Sun and is spinning with a projected rotational velocity of 70 km/s.^[6] The star is radiating 161^[6] times the Sun's luminosity from its photosphere at an effective temperature of 8,453 K.^[6]
