Star in the constellation Lyra
HD 173417 is a single
[9]
star in the northern
constellation of
Lyra . It is dimly visible to the naked eye with an
apparent visual magnitude of 5.68,
[2] positioned about two degrees to the southwest of the bright star
Sheliak .
[10] The distance to this star is approximately 169
light years based on
parallax measurements, and it is slowly drifting closer with a
radial velocity of −3 km/s.
[1]
The
stellar classification of this star is F1III-IV,
[3] matching an
evolving star with the mixed luminosity traits of a
subgiant and
giant star . It is 1.7 billion years old with a low
metallicity and a relatively high
projected rotational velocity of 54 km/s.
[7] The star has 1.6
[6] times the
mass of the Sun and 2.2 times the
Sun's radius . It is radiating over 10 times the
luminosity of the Sun from its
photosphere at an
effective temperature of 6,928 K.
