Star in the constellation Telescopium
HD 167257 (HR 6821 ) is a solitary
star in the southern
constellation
Telescopium . It has an
apparent magnitude of 6.05,
[2] making it faintly visible to the
naked eye .
Parallax measurements place the star at a distance of 420
light years
[1] and has a
radial velocity of −5.1
km/s ,
[6] which is poorly constrained. This indicates that it is drifting towards the
Solar System .
HD 167257 has a
stellar classification of B9 V,
[4] indicating that it is an ordinary
B-type main-sequence star . It has 2.63 times the
mass of the Sun ,
[3] and 2.8 times the
radius of the Sun .
[8] It shines with a
luminosity of about 65
L ☉
[3] from its
photosphere at an
effective temperature of 10,139
K ,
[9] giving it a bluish white hue. HD 167257 is estimated to be about 240
million years old
[10] – 58.6% through its
main sequence lifetime
[3] – and spins modestly with a
projected rotational velocity of 61
km/s ;
[11] it has a solar
metallicity .
