14 Sagittae is a binary star^[6] system in the equatorial constellation of Aquila.^[9] 14 Sagittae is the Flamsteed designation. It appears as a sixth magnitude star, near the lower limit of visibility to the naked eye, having an apparent visual magnitude of 5.89.^[3] The system is located 658 light years away, as determined from its annual parallax shift of 4.95 mas.^[2] It is moving closer to the Earth with a heliocentric radial velocity of –22 km/s.^[5]

This is a single-lined spectroscopic binary with an orbital period of 61.5 days and an eccentricity of 0.49.^[6] The visible component is a chemically peculiar mercury-manganese star^[10] with a stellar classification of B9p HgMn.^[4] It is narrow-lined with a projected rotational velocity of 7 km/s.^[7] The star is radiating 292^[1] times the Sun's luminosity from its photosphere at an effective temperature of 13,200 K.^[4]

John Flamsteed labelled this star as y Sagittae, but the designation was dropped by later authors and is now largely unknown.^[11]
