Star in the constellation of Telescopium
HD 182509 , also designated as HR 7370 , is an orange hued
star located in the southern
constellation
Telescopium . It has an
apparent magnitude of 5.69,
[2] making it faintly visible to the
naked eye if viewed under ideal conditions.
Parallax measurements place the object at a distance of 635
light years .
[1] It has a poorly constrained heliocentric
radial velocity of −5
km/s ,
[6] indicating that it is drifting towards the
Solar System .
HD 182509 has a
stellar classification of K4 III,
[4] indicating that it is a
red giant .
Gaia DR3
stellar evolution models place it on the
red giant branch .
[3] It has 1.12 times the
mass of the Sun
[8] but has expanded to 32.6 times its
girth .
[9] It shines with a
luminosity of 329
L ☉
[10] from its enlarged
photosphere at an
effective temperature of 4,316
K .
[9] HD 182509
iron abundance is 95% that of the
Sun , placing it at solar
metallicity .
[8] Like most giants, it spins slowly with a
projected rotational velocity of <1
km/s .
[11]
HD 182466 is a
high proper motion star located 76.1
″ away along a
position angle of 236°.
[14] Eggleton and Tokovonin (2008) list the pair as a
binary star .
[15] However, its
parallax and proper motion indicate that it is instead a foreground object.
[16] Components C and D are instead faint
optical background objects, while the E component is probably non-existent.
