Star in the constellation Aquila
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.
