HD 176527 is a single[7] star in the northern constellation of Lyra, positioned near the southern constellation border with Vulpecula. It has an orange hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.26.[1] This object is located at a distance of approximately 349 light years from the Sun based on parallax,[2] and it has an absolute magnitude of 0.28.[1] It is drifting closer with a radial velocity of −22.6 km/s.[4]
This is an aging giant star with a stellar classification of K2III,[3] which indicates it has exhausted the supply of hydrogen at its core, then evolved away from the main sequence by cooling and expanding. At present it has 24 times the radius of the Sun.[2] The star is radiating 170 times the luminosity of the Sun[2] from its swollen photosphere at an effective temperature of Script error: No such module "val"..[2]
