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.
