14 Aquilae is a probable spectroscopic binary 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, and it is located at a distance of approximately {{Convert|500|ly|pc|abbr=off|lk=on}} from Sun. The star is moving closer to the Earth with a heliocentric radial velocity of {{Val|−39|u=km/s}}, and may come as close as {{Convert|41.73|pc|ly|0|disp=out|abbr=off}} in around 3.5 million years.

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