14 Aquilae is a probable spectroscopic binary[10] star system in the equatorial constellation of Aquila. 14 Aquilae is the Flamsteed designation though it also bears the Bayer designation g Aquilae. It is visible to the naked eye as a dim, white-hued star with an apparent visual magnitude of 5.42,[2] and it is located at a distance of approximately 500 light-years (150 parsecs) from Sun. The star is moving closer to the Earth with a heliocentric radial velocity of −39 km/s,[5] and may come as close as 136 light-years in around 3.5 million years.[6]

The visible component is an A-type main sequence star with a stellar classification of A1 V.[4] It has 3.25[3] times the mass of the Sun and about twice the Sun's radius. The projected rotational velocity is relatively low[10] at 23 km/s.[8] The star is radiating 214[7] times the luminosity of the Sun from its photosphere at an effective temperature of 9,908 K.
